How to loop over specific files in python.

-

Hi all,

Generally we wish to loop over specific category of files in python. So how do we do this.

Method 1 : -

Using glob
import glob, os
os.chdir("/mydir")
for file in glob.glob("*.txt"):
    print(file)
 
Method 2 :-

Without glob 
import os
for file in os.listdir("/mydir"):
    if file.endswith(".txt"):
        print(file)
Method 3 :-

Using Os.walk 
import os
for root, dirs, files in os.walk("/mydir"):
    for file in files:
        if file.endswith(".txt"):
             print(os.path.join(root, file))

The SoX of Silence SoX is, by their own definition,  the Swiss Army knife of audio manipulation. And no doubt it’s full of fun with slicing and dicing and playback and recording and filtering and effects capabilities. But SoX is a command line tool, which means obscure syntax and parameters in order to get things done. I’ve been trying off and on for months to try to understand the  silence  filter from within SoX, which allows one to remove silence from the beginning, middle, or end of the audio. Sounds, simple, doesn’t it?  Well, it should be. Below is the  man page for the  silence  filter : silence  [-l] above-periods [duration threshold[d|%] [below-periods duration threshold[d|%]] Removes silence from the beginning, middle, or end of the audio. Silence is anything below a specified threshold. The above-periods value is used to indicate if audio should be trimmed at the beginning of the audio. A value of zero indicates no...
