Get Filename Without Extension in Python
PythonRegexPython Problem Overview
If I have a filename like one of these:
1.1.1.1.1.jpg
1.1.jpg
1.jpg
How could I get only the filename, without the extension? Would a regex be appropriate?
Python Solutions
Solution 1 - Python
In most cases, you shouldn't use a regex for that.
os.path.splitext(filename)[0]
This will also handle a filename like .bashrc
correctly by keeping the whole name.
Solution 2 - Python
>>> import os
>>> os.path.splitext("1.1.1.1.1.jpg")
('1.1.1.1.1', '.jpg')
Solution 3 - Python
You can use stem method to get file name.
Here is an example:
from pathlib import Path
p = Path(r"\\some_directory\subdirectory\my_file.txt")
print(p.stem)
# my_file
Solution 4 - Python
If I had to do this with a regex, I'd do it like this:
s = re.sub(r'\.jpg$', '', s)
Solution 5 - Python
No need for regex. os.path.splitext
is your friend:
os.path.splitext('1.1.1.jpg')
>>> ('1.1.1', '.jpg')
