What needs to be used

# os.listdir(file path (path)) List the content in the current directory
# Note: "\t" is a tab character, and "\" is an escape character, you can use "\" to escape "\ t", such as "\\t".
# os.path.isfile (file path (path)) to determine whether it is a file
# os.path.isdir (file path (path)) to determine whether it is a directory
# os.chdir() change directory change directory (enter other working directory)
# os.getcwd() Get the current working directory
# os.path.join() Join path

import os

print(os.listdir("D:\\text"))   # 内容有['text.txt', 'text2']
print(os.path.isfile("D:\\text"))  # 是否为文件False
print(os.path.isdir("D:\\text"))   # 是否为目录True
print(os.getcwd())  # 此文件路径D:\python_code\homework\modle_homework
print(os.path.join("D:\\text", "text2"))  # 拼接结果D:\text\text2
