So i've wrtitten this code:

CaseList = []
f_Case = open("C:/Users/Luke Roberts/Desktop/Lists/CaseList.txt", "r")
for line in f_Case:
    CaseList.append(line)
print(CaseList)

but when i print the list it comes out as:

['Case 1\n', 'Case 2\n', 'Case 3\n', 'Case 4\n', 'Case 5']

Is there a way to have it be added to the list without the '\n'? If not, is there a way to remove the '\n' from each string?

Any and all help is appreciated! Cheers

By default, lines are always read in from the file along with the trailing newline. Just call str.rstrip and get rid of it.

for line in f_Case:
    CaseList.append(line.rstrip())

Now, CaseList should look something like:

['Case 1', 'Case 2', 'Case 3', 'Case 4', 'Case 5']

Statutory Advice: You should wrap file I/O within a with...as context manager, it's makes for much cleaner code.

with open("C:/Users/Luke Roberts/Desktop/Lists/CaseList.txt", "r") as f_Case:
    for line in f_Case:
        CaseList.append(line)

This way, you won't have to call f_Case.close() (which you don't currently do, but should've), so you've got the added convenience to go with the safety.

  • Keep in mind that `line.rstrip()` will remove more than just newlines. You may want to use `line.rstrip('\r\n')` instead. – Aran-Fey Aug 28 '17 at 00:43
