How to find current directory and file directory

There are two functions under the os module:

os.walk()

os.listdir()

# -*- coding: utf-8 -*-   
    import os   
    def file_name(file_dir):   
        for root, dirs, files in os.walk(file_dir):  
            print(root) #当前目录路径  
            print(dirs) #当前路径下所有子目录  
            print(files) #当前路径下所有非目录子文件

The output format is:

Current file directory path

Sub-file directory under the current path (if it exists, [] if it does not exist)

Under the current path Non-directory subfile (only the file name of the subfile)

Case:

# -*- coding: utf-8 -*-   
      
    import os  
      
    def file_name(file_dir):   
        L=[]   
        for root, dirs, files in os.walk(file_dir):  
            for file in files:  
                if os.path.splitext(file)[1] == '.jpeg':  
                    L.append(os.path.join(root, file))  
        return L  
#其中os.path.splitext()函数将路径拆分为文件名+扩展名
