List files with a specific extension

[pyth0nus3r]

Hello
I wanted to know if it is possible to list a particular type of file (let's say .mp4) from a directory recursively.
I can list all files recursively within a particular directory but I don't how to search for files with specific extension.

Thanks

you can use os.path.splitext() or str method .endswith() to check filename ext

You are asking to list all files in a directory tree?

I can list all files recursively within a particular directory but I don't how to search for files with specific extension.

You can use os.walk() or better os.scandir()(a lot faster) for Python 3.5-->
These do recursively scan whole folder.
Eg.

import os

source = 'path'
for root,dirs,files in os.scandir(source):
    for file_name in files:
        if file_name.endswith(('.jpg', '.jpeg', '.mp4')):
            print(file_name)

[wavic]

scandir(path) do not scan the sub-directories.

for root, dirs, files in os.walk(path):
    if files:
        for file in files:
            if os.path.splitext(file)[1] == '.mp3':
                print(file)

[snippsat]

scandir(path) do not scan the sub-directories.

Okay thanks for info,look like they build scandir() into os.walk().
I did try it before it went into standard library,
from GitHub and then it did work like os.walk().

os.walk()

As part of this proposal, os.walk() will also be modified to use scandir() rather than listdir() and os.path.isdir() .
This will increase the speed of os.walk() very significantly (as mentioned above, by 2-20 times, depending on the system)

Look better with endswith():

if os.path.splitext(file)[1] == '.mp3':
# Or
if file.endswith('.mp3')

[wavic]

And they say that scandir() has significant speed improvement especially on Windows. Since 3.5

[snippsat]

Yes the speed is better,i did make this in 2014 Picture/Movie-Collector.
So here use scandir before it went into standard library.
I see in my code that is was scandir.walk(path),which now is build into os.walk().

Speed

about 7-50 times as fast on Windows, and about 3-10 times as fast on Linux and Mac OS X.
