I cannot seem to not input the current_data if it matches the value in the file. I only want to append the file if it is a new value. What am I doing wrong?

I need to use changed text document (from a function changed_document) in a function called lines. But I cannot just simply use the changed list or string. It shows me an error that "AttributeError: 'str' object has no attribute 'readlines'". So I've tried to write the changed text in to a new text file and then read it to use in the line function. But it doesn't work. I cannot read that newly written text file. It prints just empty lines.
def reading():
doc = open("C:/Users/s.txt", "r", encoding= 'utf-8')
docu = doc
return docu
def longest_word_place(document):
words = document.read().split()
i = 0
max = 0
max_place = 0
for i in range(len(words)):
if len(words[i]) > max:
max = len(words[i])
max_place = i
return max_place
def changed_document (document):
list = []
for line in document:
for symbol in line:
if symbol.isnumeric():
symbol = ' '
if symbol in "#,.;«\³][:¡|>^' '<?+=_-)(*&^%$£!`":
symbol = ' '
list.append(symbol)
document_changed =''.join([str(item) for item in list])
return document_changed
def lines(document):
lines = document.readlines()
max_word = ''
max_line = 0
for line_index, every_line in enumerate(lines, 1):
line_words = every_line.strip().split()
for each_word in line_words:
if len(each_word) > len(max_word):
max_word = each_word
max_line = line_index
print(f"{max_word = }, {max_line = }")
document = reading()
ch_dok = changed_document(document)
text_file = open("C:/Users/changed_doc.txt", "w+", encoding= 'utf-8')
text_file.write(ch_dok)
text_file.close
doc1 = open("C:/Users/changed_doc.txt", "r", encoding= 'utf-8')
for line1 in doc1:
print(line1)
In "text_file.close" you missed the parenthesis, so the file is not closed (just the function itself is returned, not called).
Perhaps this is the issue..?
The task is to read from given txt file the data add the numbers in there to the list[], so that every number in a row will be a element/object in this list. After reading the file created list will be sent to the main().
this list with the objects will be parameters for the def Analyze part in where at the same time
will be found min, max, average and sum.
def lueTiedosto(data):
Tiedosto = open("L07T4D1.txt", 'r', encoding="UTF-8")
Rivi = Tiedosto.readline()
while (len(Rivi) > 0):
data.append(int(Rivi))
Rivi = Tiedosto.readline()
for element in data:
print(element)
print(f"Tiedosto L07T4D1.txt luettu.")
Tiedosto.close()
return element
The fixed code which works:
def lueTiedosto(data):
Lue = input("Luettavan tiedoston nimi on ''.\n")
print(f"Anna uusi nimi, enter säilyttää nykyisen: ", end='')
Tiedosto = open(Lue, 'r', encoding="UTF-8")
Rivi = Tiedosto.readline()
while (len(Rivi) > 0):
data.append(int(Rivi))
Rivi = Tiedosto.readline()
print(f"Tiedosto '{Lue}' luettu.")
Tiedosto.close()
return data
Making an assumption that your input file is similar to the following:
10000
12345
10008
12000
I would do the following:
filepath = r".......\L07T4D1.txt" # Path to file being loaded
def readData(filepath: str) -> list[int]:
# Returns a list of integers from file
rslt = []
with open (filepath, 'r') as f:
data = f.readline().strip()
while data:
data = data.split(' ')
rslt.append(int(data[0]))
data = f.readline().strip()
return rslt
def analyze(data: list[int]) -> None:
# prints results of data analysis
print(f'Max Value = {max(data)}')
print(f'Min Value = {min(data)}')
print(f'Sum Value = {sum(data)}')
print(f'Avg Value = {sum(data)/len(data)}')
Running analyze(readData(filepath)) Yields:
Max Value = 12345
Min Value = 10000
Sum Value = 44353
Avg Value = 11088.25
The goal is to extract specific data from a text file under a folder
then write that data into another file under different folder

I'm getting number from a HTML, some of them are %, 4 digits and 7 digits (37.89%, 3.464, 2,193.813). I would like to save just the numbers, not the percentages, without the thousand separators (".").

I don't know all your input parameters, but this works for the ones that you provided.
s = ('37.89%', '3.464', '2,193.813')
for item in s:
remove_comma = item.replace(',', '')
keep_percentage = re.findall(r'\d{1,4}\.\d{1,4}%', remove_comma)
if keep_percentage:
keep_percentage = ''.join(keep_percentage)
print (keep_percentage)
else:
if (len(remove_comma)) == 5:
print (remove_comma.replace('.', ''))
else:
print (remove_comma.replace('.', ','))
**OUTPUTS**
