如何使python发现文件夹并打印其文件

Question

I want to be able to make python print everything in my C drive. I have figured out this to print whats on the first "layer" of the drive,

def filespotter():
import os
path = 'C:/'
dirs = os.listdir( path )
for file in dirs:
    print(file)

but I want it to go into the other folders and print what is in every other folder.

Disclaimer os.walk is just fine, I'm here to provide a easier solution.

If you're using python 3.5 or above, you can use glob.glob with '**' and recursive=True

For example: glob.glob(r'C:\\**', recursive=True)

Please note that getting the entire file list of C:\\ drive can take a lot of time.

If you don't need the entire list at the same time, glob.iglob is a reasonable choice. The usage is the same, except that you get an iterator instead of a list.

To print everything under C:\\

for filename in glob.iglob(r'C:\**', recursive=True):
    print(filename)

It gives you output as soon as possible.

However if you don't have python 3.5 available, you can see the source of glob.py and adapt it for your use case.
