I am trying to make my own text editor where it asks for a file and prints a > that can then be moved to the specified index of the line so that it can then delete a character. I don't know the best way to move it. So far I have
def print_file(data, cursor):
"""Prints the file contents (data), with the cursor in the right place."""
# Variable fm will store the formatted representation
# of the file with position information, etc.
fm = ""
pos = 0
# Break the "file" (represented by a string) up into lines.
lines = data.split("\n")
for x, line in enumerate(lines):
length = len(line)
if length != 0:
# Edge case for the end of the "file".
if data[-1] != "\n" and x == len(lines) - 1:
length -= 1
fm += str("{0:70} |{1:3d}:{2:3d}|\n".format(line, pos, pos + length))
# If the cursor points to char on this line add it.
if pos <= cursor <= pos + length:
fm += " " * (cursor - pos) + "^\n"
# Start at the next character.
pos += length + 1
print(fm, end="")
#end of function
def move_cursor(location):
"""Moves the cursor to the right location"""
#end of function
cursor = 0
is_open = False
is_modified = False
file = str(input(">open "))
#Open filename
file == "(filename)"
file = open(file, "r")
file_data = file.read()
print_file(file_data, cursor)
command = str(input("> "))
#Move position
if command == "move(int)":
move_cursor(location)
I think the best way would be to make a function and then call it inside the loop, but am unsure how to actually get it to move to the index....

I am having a problem with my code trying to do an advanced caesar cipher shift. I changed a certain letter to another, and then added a string to certain parts of a file before encoding, but am having problems doing the shifting now. This is my code:
import string
import sys
count = 1
cont_cipher = "Y"
#User inputs text
while cont_cipher == "Y":
if count == 1:
file = str(input("Enter input file:" ""))
k = str(input("Enter shift amount: "))
purpose = str(input("Encode (E) or Decode (D) ?: "))
#Steps to encode the message, replace words/letter then shift
if purpose == "E":
my_file = open(file, "r")
file_contents = my_file.read()
#change all "e"s to "zw"s
for letter in file_contents:
if letter == "e":
file_contents = file_contents.replace(letter, "zw")
#add "hokie" to beginning, middle, and end of each line
lines = file_contents.split('\n')
def middle_message(lines, position, word_to_insert):
lines = lines[:position] + word_to_insert + lines[position:]
return lines
new_lines = ["hokie" + middle_message(lines[x], len(lines[x])//2, "hokie") + "hokie" for x in range(len(lines))]
#math to do the actual encryption
def caesar(word, shifts):
word_list = list(new_lines)
result = []
s = 0
for c in word_list:
next_ord = ord(c) + s + 2
if next_ord > 122:
next_ord = 97
result.append(chr(next_ord))
s = (s + 1) % shifts
return "".join(result)
if __name__ == "__main__":
print(caesar(my_file, 5))
#close file and add to count
my_file.close()
count = count + 1
The error I am getting is:
TypeError: ord() expected a character, but string of length 58 found
I know that I need to split it into individual characters, but am not sure how to do this. I need to use the updated message and not the original file in this step...
I am trying to print the word and line number(s) where the word occurs in the file in Python. Currently I am getting the correct numbers for second word, but the first word I look up does not print the right line numbers. I must iterate through infile, use a dictionary to store the line numbers, remove new line chars, remove any punctuation & skip over blank lines when pulling the number. I need to add a value that is actually a list, so that I may add the line numbers to the list if the word is contained on multiple lines.
Adjusted code:
def index(f,wordf):
infile = open(filename, 'r')
dct = {}
count = 0
for line in infile:
count += 1
newLine = line.replace('\n', ' ')
if newLine == ' ':
continue
for word in wordf:
if word in split_line:
if word in dct:
dct[word] += 1
else:
dct[word] = 1
for word in word_list:
print('{:12} {},'.format(word,dct[word]))
infile.close()
Current Output:
>>> index('leaves.txt',['cedars','countenance'])
pines [9469, 9835, 10848, 10883],
counter [792, 2092, 2374],
Desired output:
>>> index2('f.txt',['pines','counter','venison'])
pines [530, 9469, 9835, 10848, 10883]
counter [792, 2092, 2374]
There is some ambiguity for how your file is set up, but I think it understand.
Try this:
import numpy as np # add this import
...
for word in word_f:
if word in split_line:
np_array = np.array(split_line)
item_index_list = np.where(np_array == word)
dct[word] = item_index_list # note, you might want the 'index + 1' instead of the 'index'
for word in word_f:
print('{:12} {},'.format(word,dct[word]))
...
btw, as far as I can tell, you're not using your 'increment' variable.
I think that'll work, let me know if it doesn't and I'll fix it
per request, I made an additional answer (that I think works) without importing another library
def index2(f,word_f):
infile = open(f, 'r')
dct = {}
# deleted line
for line in infile:
newLine = line.replace('\n', ' ')
if newLine == ' ':
continue
# deleted line
newLine2 = removePunctuation(newLine)
split_line = newLine2.split()
for word in word_f:
count = 0 # you might want to start at 1 instead, if you're going for 'word number'
# important note: you need to have 'word2', not 'word' here, and on the next line
for word2 in split_line: # changed to looping through data
if word2 == word:
if word2 in dct:
temp = dct[word]
temp.append(count)
dct[word] = temp
else:
temp = []
temp.append(count)
dct[word] = temp
count += 1
for word in word_f:
print('{:12} {},'.format(word,dct[word]))
infile.close()
Do be aware, I don't think this code will handle if the words passed in are not in the file. I'm not positive on the file that you're grabbing from, so I can't be sure, but I think it'll seg fault if you pass in a word that doesn't exist in the file.
Note: I took this code from my other post to see if it works, and it seems that it does
def index2():
word_list = ["work", "many", "lots", "words"]
infile = ["lots of words","many many work words","how come this picture lots work","poem poem more words that rhyme"]
dct = {}
# deleted line
for line in infile:
newLine = line.replace('\n', ' ') # shouldn't do anything, because I have no newlines
if newLine == ' ':
continue
# deleted line
newLine2 = newLine # ignoring punctuation
split_line = newLine2.split()
for word in word_list:
count = 0 # you might want to start at 1 instead, if you're going for 'word number'
# important note: you need to have 'word2', not 'word' here, and on the next line
for word2 in split_line: # changed to looping through data
if word2 == word:
if word2 in dct:
temp = dct[word]
temp.append(count)
dct[word] = temp
else:
temp = []
temp.append(count)
dct[word] = temp
count += 1
for word in word_list:
print('{:12} {}'.format(word, ", ".join(map(str, dct[word])))) # edited output so it's comma separated list without a trailing comma
def main():
index2()
if __name__ == "__main__":main()
and the output:
work 2, 5
many 0, 1
lots 0, 4
words 2, 3, 3
and the explanation:
infile = [
"lots of words", # lots at index 0, words at index 2
"many many work words", # many at index 0, many at index 1, work at index 2, words at index 3
"how come this picture lots work", # lots at index 4, work at index 5
"poem poem more words that rhyme" # words at index 3
]
when they get appended in that order, they get the correct word placement position
My biggest error was that I was not properly adding the line number to the counter. I completely used the wrong call, and did nothing to increment the line number as the word was found in the file. The proper format was dct[word] += [count] not dct[word] += 1
def index(filename,word_list):
infile = open(filename, 'r')
dct = {}
count = 0
for line in infile:
count += 1
newLine = line.replace('\n', ' ')
if newLine == ' ':
continue
newLine2 = removePunctuation(newLine)
split_line = newLine2.split()
for word in word_list:
if word in split_line:
if word in dct:
dct[word] += [count]
else:
dct[word] = [count]
for word in word_list:
print('{:12} {}'.format(word,dct[word]))
infile.close()
Here is the full code, it is for a basic random alphabetical shift encryption. For some reason, the .write() don't seem to be working.
from random import randint
import time
import os
sentence = input('What do you want to encrypt? ').lower()
namefile = input('What do you want to call the encrypted file? ')
alphabet = {'a':0,'b':1,'c':2,'d':3,'e':4,'f':5,'g':6,'h':7,'i':8,'j':9,'k':10,'l':11,'m':12,'n':13,'o':14,'p':15,'q':16,'r':17,'s':18,'t':19,'u':20,'v':21,'w':22,'x':23,'y':24,'x':25,' ':26,'.':27}
alphabet1 = {0:'a',1:'b',2:'c',3:'d',4:'e',5:'f',6:'g',7:'h',8:'i',9:'j',10:'k',11:'l',12:'m',13:'n',14:'o',15:'p',16:'q',17:'r',18:'s',19:'t',20:'u',21:'v',22:'w',23:'x',24:'y',25:'x',26:' ',27:'.'}
shift = randint(1,27)
x = len(sentence)
y = 0
encrypted_file = open(namefile + '.txt', 'wt')
while y < x:
letter = sentence[y]
position = alphabet[letter]
position = position + shift
if position > 27:
position = position - 27
letter = alphabet1[position]
Here is the first .write(). This one is inside a loop.
encrypted_file.write(letter)
y = y + 1
This is the second .write(). This is a single use one
encrypted_file.write('\nEncryption Shift = ' + str(shift))
encrypted_file.close
time.sleep(2)
print('Done')
time.sleep(1)
print('Here is your encrypted file.')
time.sleep(2)
os.startfile('C:/Users/Jedidiah/Documents/' + namefile + '.txt')
The mode key "wt" doesn't exist.
check here! for all proper mode keys
UPDATE: try this
from random import randint

shift = randint(1,27)
x = len(sentence)
y = 0
encrypted_file = open(namefile + '.txt', 'a')
while y < x:
letter = sentence[y]
position = alphabet[letter]

letter = alphabet1[position]
encrypted_file.write(letter)

if you want to overwrite the file use "w" for the mode key
I am making a connect four like game in python, what I have so far is creating the board and implementing game play against the computer. I am running into the issue that does not allow me to play past the second row. Any ideas on why?
#Define the board
row = int(input("Please enter # of rows: ")) #User input Rows
column = int(input("Please enter # of columns: ")) #User input Columns
board = [] #empty board
space = ' '
p1 = 'x'
p2 = 'o'
#create board based on user input
for i in range(0,row):
board.append([])
for j in range(0, column):
board[i].append(space)
print(board)
#print board with character decorations
for i in board:
line=''
print('+'+'-+'*len(i))
for j in range(len(i)):
line = line + '|'+i[j]
line = line + '|'
print(line)
print('+'+'-+'*len(i))
print(len(board))
while True:
#User input column
myC = int(input("Player 1, choose your column: "))
i = len(board)-1
x = len(board)-1
while i >= 0:
if board[x][myC] == space:
i = i+1
board[x][myC] = 'x'
break
elif board[x][myC] == p1 or p2:
i = i+1
x = x - 1
print(x)
board[x][myC] = 'x'
break
# print the board!
for i in board:
line=''
print('+'+'-+'*len(i))
for j in range(len(i)):
line = line + '|'+i[j]
line = line + '|'
print(line)

#Computer input column
from random import randint

I believe I figured out what's going on. Your x is always initialized to len(board)-1 and then if the space is occupied it is reduced by one. If you make a (>2)x(>2) board and row 0 is occupied then this will always force x = 2.
This is close to correct, but what you actually need is to iterate through all rows until you find the first unoccupied row. I created a loop that will find the first row and assign that to the value of x. I tested it out and I'm now able to play passed 2 rows.
#Define the board
row = int(input("Please enter # of rows: ")) #User input Rows
column = int(input("Please enter # of columns: ")) #User input Columns
board = [] #empty board
space = ' '
p1 = 'x'
p2 = 'o'
#create board based on user input
for i in range(0,row):
board.append([])
for j in range(0, column):
board[i].append(space)
print(board)
#print board with character decorations
for i in board:
line=''
print('+'+'-+'*len(i))
for j in range(len(i)):
line = line + '|'+i[j]
line = line + '|'
print(line)
print('+'+'-+'*len(i))
print(len(board))
while True:
#User input column
myC = int(input("Player 1, choose your column: "))
i = len(board)-1
x = len(board)-1

if board[x][myC] == space:
i = i+1

if board[j][myC] == space:
x = j

I don't know where does it goes wrong. I can get the correct result if I just call out my valid_ISBN(isbn) function, but when I write the file, the result become all invalid. (maybe something wrong with function call, but I don't know how to fix it)
def main():
# Call and open the File
inFile = open("isbn.txt", "r")
for line in inFile:
line_strip = line.replace("-", "").replace(" ", "").rstrip("\n")
isbn = line_strip # the function call
# Output file
str = []
str.append(line)
outFile = open("isbnOut.txt", "a")
for i in str:
if valid_ISBN(isbn) == "valid":
outFile.write(i.strip() + " valid\n")
else:
outFile.write(i.strip() + " invalid\n")
inFile.close()
outFile.close()
def valid_ISBN(isbn):
if len(isbn) != 10 or (isbn[0:9].isdigit()) == False:
print("invalid")
else:
return partial_sums(isbn)
def partial_sums(s1):
lst1 =[]
sum1 = 0
for i in range(len(s1)):
if (i == (len(s1) -1)) and ((s1[i] == "x") or (s1[i] == "X")):
sum1 = sum1 + 10
else:

2 Test case for isbn text file (no new line):
019-923-3241
818-851-703X
In your main function:
Every time you read a line in from your input file you initialize str and fill it with just one value. You open your output file, do your validity checks for your one value in str, and finally write the one value to the the output file.
The next time you read the file you do the same stuff... so str isn't needed at all
Also using str as a variable name is bad form. In your console write in help(str) and you will see why.
Now to deal with your actual complaint:
Your problem is the fact that there is no new line.
when you say for line in some_open_file_handler:... what python does is populate line with everything up to the next newline character or the end of the file.
If your input file has no new lines seperating isbns then the first value of line would be 019-923-3241 818-851-703X. Thus the line line_strip = line.replace("-", "").replace(" ", "").rstrip("\n") set linestrip to 0199233241818851703X
This should fix it:
'line.split() will yield ['019-923-3241','818-851-703X']
outFile = open("isbnOut.txt", "a")
for line in open("isbn.txt", "r"):
isbns = line.split() #this splits stuff up by whitespace.
for isbn in isbns:
isbn = isbn.replace("-", "").replace(" ", "").rstrip("\n")
if valid_ISBN(isbn) == "valid":
outFile.write(i.strip() + " valid\n")
else:
outFile.write(i.strip() + " invalid\n")
