How do I get the filename without the extension from a path in Python?
Getting the name of the file without the extension:
import os
print(os.path.splitext("/path/to/some/file.txt")[0])
Prints:
/path/to/some/file
Documentation for os.path.splitext
.
Important Note: If the filename has multiple dots, only the extension after the last one is removed. For example:
import os
print(os.path.splitext("/path/to/some/file.txt.zip.asc")[0])
Prints:
/path/to/some/file.txt.zip
See other answers below if you need to handle that case.
Get Filename Without Extension in 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.
get filenames in a directory without extension - Python
You can use os
's splitext.
import os
path = '/Users/vivek/Desktop/buffer/xmlTest/'
files = [os.path.splitext(filename)[0] for filename in os.listdir(path)]
print (files)
Just a heads up: basename
won't work for this. basename
doesn't remove the extension.
Extract file name from path, no matter what the os/path format
Using os.path.split
or os.path.basename
as others suggest won't work in all cases: if you're running the script on Linux and attempt to process a classic windows-style path, it will fail.
Windows paths can use either backslash or forward slash as path separator. Therefore, the ntpath
module (which is equivalent to os.path when running on windows) will work for all(1) paths on all platforms.
import ntpath
ntpath.basename("a/b/c")
Of course, if the file ends with a slash, the basename will be empty, so make your own function to deal with it:
def path_leaf(path):
head, tail = ntpath.split(path)
return tail or ntpath.basename(head)
Verification:
>>> paths = ['a/b/c/', 'a/b/c', '\\a\\b\\c', '\\a\\b\\c\\', 'a\\b\\c',
... 'a/b/../../a/b/c/', 'a/b/../../a/b/c']
>>> [path_leaf(path) for path in paths]
['c', 'c', 'c', 'c', 'c', 'c', 'c']
(1) There's one caveat: Linux filenames may contain backslashes. So on linux, r'a/b\c'
always refers to the file b\c
in the a
folder, while on Windows, it always refers to the c
file in the b
subfolder of the a
folder. So when both forward and backward slashes are used in a path, you need to know the associated platform to be able to interpret it correctly. In practice it's usually safe to assume it's a windows path since backslashes are seldom used in Linux filenames, but keep this in mind when you code so you don't create accidental security holes.
How to get only filename without extension?
If the column values are always the filename/filepath, split it from right on .
with maxsplit parameter as 1
and take the first value after splitting.
>>> df['relfilepath'].str.rsplit('.', n=1).str[0]

How to get a specific file name from a path without the extensions python
may be funny and dirty, but works :)
sample_name = os.path.splitext(os.path.splitext(os.path.basename(f_file))[0])[0]
also can use shorter, nicer version:
sample_name = os.path.basename(f_file).split('.')[0]
Get file name only (without extension and directory) from file path
Your code works exactly as it should. In example a, the \n is not treated as a backslash character because it is a newline character. In example b, the extension is .mpg, which is properly removed. A file can never have more than one extension, or an extension containing a period.
To only get the bit before the first period, you could use ntpath.basename(filepath).split('.')[0]
, but this is probably NOT what you want as it is perfectly legal for filenames to contain periods.
Extracting extension from filename in Python
Use os.path.splitext
:
>>> import os
>>> filename, file_extension = os.path.splitext('/path/to/somefile.ext')
>>> filename
'/path/to/somefile'
>>> file_extension
'.ext'
Unlike most manual string-splitting attempts, os.path.splitext
will correctly treat /a/b.c/d
as having no extension instead of having extension .c/d
, and it will treat .bashrc
as having no extension instead of having extension .bashrc
:
>>> os.path.splitext('/a/b.c/d')
('/a/b.c/d', '')
>>> os.path.splitext('.bashrc')
('.bashrc', '')
How can I replace (or strip) an extension from a filename in Python?
Try os.path.splitext it should do what you want.
import os
print os.path.splitext('/home/user/somefile.txt')[0]+'.jpg' # /home/user/somefile.jpg
os.path.splitext('/home/user/somefile.txt') # returns ('/home/user/somefile', '.txt')
How to get filename using os.path.basename without the '> extension
You need to use filedialog.askopenfilename
instead of filedialog.askopenfile
to obtain the filename without side effects (like opening a file). This returns the full path; you can extract the filename from the fullpath using os.path.basename
import os
import tkinter as tk
from tkinter import filedialog
def browse():
root = tk.Tk()
root.withdraw()
fullpath = filedialog.askopenfilename(parent=root, title='Choose a file')
filename = os.path.basename(fullpath)
root.destroy()
return filename
print(browse())
