Python string alphabet removal?

Question

So in my program, I am reading in files and processing them.

My output should say just the file name and then display some data

When I am looping through files and printing output by their name and data,

it displays for example: myfile.txt. I don't want the .txt part. just myfile.

how can I remove the .txt from the end of this string?

The best way to do it is in the example

import os

filename = 'myfile.txt'

print(filename)
print(os.path.splitext(filename))
print(os.path.splitext(filename)[0])

Thanks for your input, but since I am not using os. I used the one below. – TwinDream Dec 11 '19 at 21:23

The answers given are totally right, but if you have other possible extensions, or don't want to import anything, try this:

name = file_name.rsplit(".", 1)[0]

You can use pathlib.Path which has a stem attribute that returns the filename without the suffix.

>>> from pathlib import Path
>>> Path('myfile.txt').stem
'myfile'

Well if you only have .txt files you can do this

file_name = "myfile.txt"
file_name.replace('.txt', '')

This uses the built in replace functionality. You can find more info on it here!

What if the file does not end with `.txt`? – chrisbyte Dec 11 '19 at 21:19
@chrisbyte you could also split on the "." and just print the 1st result in the list it returns – J_C Dec 11 '19 at 21:21

Periods are legal in file names, and some files can be called `my.file.txt`. It would only return the `my` – chrisbyte Dec 11 '19 at 21:23
@chrisbyte the split method returns a list so in that case you can remove the last item in the list and reconstruct the remaining items with a .join() – J_C Dec 12 '19 at 20:46
