like in python i can simply take the whole text in """ and it will be stored as you wrote it inside the """'s
outText = """ some text that doesn't contain "\n" and
everything can be outputted with 1 print command """
print outText
Is it possible to hold the whole text inside some kind of brackets and print out the text without puts-ing every single line one by one or using \n in every end of line?
Use braces:
set outText {some text that doesn't contain "\n" and
everything can be outputted with 1 put command}
puts $outText

With this input
x 1
x 2
x 3
y 1
y 2
y 3
I'd like to have this output
x 1;2;3
y 1;2;3
Thank you in advance,

If by terminal you mean something natively built in you might not be in much luck, however you could run a python file from the terminal which could do want you want and more. If having a standalone file isn't possible then you can always run python in REPL mode for purely terminal usage.
If you have python installed all you would need to do to access REPL would be "py" and you could manually setup a processor. If you can use a file then something like this below should be able to take any input text and output the formatted text to the terminal.
file = open("data.txt","r")
lines = file.readlines()
same_starts = {}
#parse each line in the file and get the starting and trailing data for sorting
for line in lines:
#remove trailing/leading whitesapce and newlines
line_norm = line.strip()#.replace('\n','')
#splits data by the first space in the line
#formatting errors make the line get skipped
try:
data_split = line_norm.split(' ')
start = data_split[0]
end = data_split[1]
except:
continue
#check if dictionary same_starts already has this start
if same_starts.get(start):
same_starts[start].append(end)
else:
#add new list with first element being this ending
same_starts[start] = [end]
#print(same_starts)
#format the final data into the needed output
final_output = ""
for key in same_starts:
text = key + ' '
for element in same_starts[key]:
text += element + ";"
final_output += text + '\n'
print(final_output)
NOTE: final_output is the text in the final formatting
assuming you have python installed then this file would only need to be run with the current directory being the folder where it is stored along with a text file called "data.txt" in the same folder which contains the starting values you want processed. Then you would do "py FILE_NAME.ex" ensuring you replace FILE_NAME.ex with the exact same name as the python file, extension included.
I am doing this as an assignment. So, I need to read a file and remove lines that start with a specific word.
fajl = input("File name:")
rec = input("Word:")
def delete_lines(fajl, rec):
with open(fajl) as file:
text = file.readlines()
print(text)
for word in text:
words = word.split(' ')
first_word = words[0]
for first in word:
if first[0] == rec:
text = text.pop(rec)
return text
print(text)
return text
delete_lines(fajl, rec)
At the last for loop, I completely lost control of what I am doing. Firstly, I can't use pop. So, once I locate the word, I need to somehow delete lines that start with that word. Additionally, there is also one minor problem with my approach and that is that first_word gets me the first word but the , also if it is present.
Example text from a file(file.txt):
This is some text on one line.
The text is irrelevant.
This would be some specific stuff.
However, it is not.
This is just nonsense.
rec = input("Word:") --- This
Output:
The text is irrelevant.
However, it is not.
You cannot modify an array while you are iterating over it. But you can iterate over a copy to modify the original one
fajl = input("File name:")
rec = input("Word:")
def delete_lines(fajl, rec):
with open(fajl) as file:
text = file.readlines()
print(text)
# let's iterate over a copy to modify
# the original one without restrictions
for word in text[:]:
# compare with lowercase to erase This and this
if word.lower().startswith(rec.lower()):
# Remove the line
text.remove(word)
newtext="".join(text) # join all the text
print(newtext) # to see the results in console
# we should now save the file to see the results there
with open(fajl,"w") as file:
file.write(newtext)
print(delete_lines(fajl, rec))
Tested with your sample text. if you want to erase "this". The startswith method will wipe "this" or "this," alike. This will only delete the text and let any blank lines alone. if you don't want them you can also compare with "\n" and remove them
How can I find in file particular text '12345' and get all lines up and down till to the 'Received notification:' using linux console commands without hardcoding numbers of lines for up and down?
Received notification:
Random text
Random text
...
12345
random text

You can use the following approach:
$ awk '/str1/ {p=1}; p; /str2/ {p=0}' file
When it finds str1, then makes variable p=1. It just prints lines when p==1. This is accomplished with the p condition. If it is true, it performs the default awk action, that is, print $0. Otherwise, it does not.
When it finds str2, then makes variable p=0. As this condition is checked after p condition, it will print the line in which str2 appears for the first time.
I need to read a text file which contains csv data with headers separating individual blocks of data. The headers always start with the dollar sign $. So my text file looks like:
$Header1
2
1,2,3,4
2,4,5,8
$Header2
2
1,1,0,19,9,8
2,1,0,18,8,7
What I want to do is if the program reaches to $Header2, I want to read all the next lines following it till it reaches, say, $Header3 or end of the file. I think I can use `cmp' in Julia for this. I tried with a small file that contains following text:
# file julia.txt
Julia
$Julia
and my code reads:
# test.jl
fname = "julia.txt"
# set some string values
str1 ="Julia";
str2 ="\$Julia";
# print the strings and check the length
println(length(str1),",",str1);
println(length(str2),",",str2);
# now read the text file to check if you are able to find the strings
# str1 and str2 above
println ("Reading file...");
for ln in eachline(fname)
println(length(ln),",",ln);
if (cmp(str1,ln)==0)
println("Julia match")
end
if (cmp(str2,ln)==0)
println("\$Julia match")
end
end
what I get as output from the above code is:
5,Julia
6,$Julia
Reading file...
6,Julia
7,$Julia
I don't understand why I get character length of 6 for string Julia and 7 for the string $Julia when they are read from the file. I checked the text file by turning on white spaces and there are none. What am i doing wrong?
The issue is that the strings returned by eachline contain a newline character at the end.
You can use chomp to remove it:
julia> first(eachline("julia.txt"))
"Julia\n"
julia> chomp(first(eachline("julia.txt")))
"Julia"
Also, you can simply use == instead of cmp to test whether two strings are equal. Both use a ccall to memcmp but == only does that for strings of equal length and is thus probably faster.
I have a csv file that is being fed to my Python script via stdin.
This is a comma separated file with quotations as text delimiter.
Here is an example line:
457,"Last,First",NYC
My script so far, splits each line by looking for commas, but how do I make it aware of the text delimiter quotes?
My current script:
for line in sys.stdin:
line = line.strip()
line.split(',')
print line
The code splits the name into two since it does not recognize the quotations enclosing that text field. I need the name to remain as a single element.
If it matters, the data is being fed through stdin within a hadoop-streaming program.
Thanks!
Well, you could do it more manually, with something like this:
row = []
enclosed = False
word = ''
for character in sys.stdin:
if character == '"':
enclosed = not enclosed
elif character = ',' and not enclosed:
row.append(word)
word = ''
else:
word += character
Haven't tested nor thought about it for too long but seems to me it could work. Probably someone more into Pythonist sintax could fine something better for doing the trick although ;)
Attempting to answer my own question. If I read right, it may be possible to send a streaming input into csv reader like so:
for line in csv.reader(sys.stdin):
print line
