os.listdir(path) 

Trigger

It all started when I wanted to list the documents in Downloads.

Details

Examine the path

#Method 1 option+command+C
#On Mac, you can get "absolute PATH" by pressing "option", "command", and "C" while selecting a file.
#Example:/Users/"User name"/Downloads/"File name"'

#Method 2
#Search for file names
#During study

Get files and folders with listdir

#This time, get the Downloads data
import os
path = '/Users/username/Downloads'
files = os.listdir(path)
for file in files:
    print(file)

Added: glob () is also useful

extension(.pdf)I want to check the file name by specifying

import glob
path = '/Users/username/Downloads'
print(glob.glob(path+'/*.pdf'))

If you want to search only now

I want to find out the path of the current file (absolute path)

Current directory

import os
print(os.getcwd())

For example, I'm writing python in spyder, so

/Users/username/.spyder-py3

Will be returned.

I want to check the current file by specifying the extension (.py) (file name)

Specify extension

import glob
glob.glob('*.py')

In the /Users/username/.spyder-py3 file

untitled0.py temp.py template.py history_internal.py history.py

Was returned when it was included.
