Python - Get File and Path Parts (Dirname, Base Name, Extension)
To split the full file name (e.g. /root/dir/sub/file.ext) with a path into various parts you can use python built-in functions from the os module.
You can retrieve:
- base name - just file name with extension (in our example:
file.ext) - file path (in our example:
/root/dir/sub/) - core name from the file name (in our example:
file) - extension from the file name (in our example:
.ext)
See the code below:
import os
full_file = '/root/dir/sub/file.ext'
# file name with extension
basename = os.path.basename(full_file)
print(f'basename: {basename}')
# full path to file
dirname = os.path.dirname(full_file)
print(f'dirname: {dirname}')
# extract core name and extension from the filename
core_name, ext = os.path.splitext(basename)
print(f'core_name: {core_name}', f'ext: {ext}')
Example results:
>>> import os
>>> base=os.path.basename('/root/dir/sub/file.ext')
>>> base
'file.ext'
>>> os.path.splitext(base)
('file', '.ext')
>>> os.path.splitext(base)[0]
'file'
