I want to remove a file's last characters that it's name is somedigits plus .py and plus .BR like 0001.py.BR or 0005.py.BR and remove the .BR from the string.
I tried this code
import os
x = input("")
os.rename(x, x[7])
but it sometimes don't work for some file that their names are larger like 00001.py.BR it renames it to 00001.p so is there a way that I just do like this x - ".BR".
if you talking about file path,
then use os.path.splitext()
>>> import os
>>> os.path.splitext('00001.py.BR')[0]
'00001.py'
>>>
You can use the built-in split function like this:
import os
x=input("")
x_new = x.split(".BR")[0]
os.rename(x, x_new)
If you're using Python 3, check the standard pathlib:
from pathlib import Path
old_path = Path(input(""))
if old_path.suffix == '.BR':
old_path.rename(old_path.stem)
else:
print('this is not a .BR file')
os.rename(x, x[:-3])
