我在Python 3.6中收到错误“ os.chdir（saved_pa​​th）处的无效错误”

Question

#importing the os library 
    import os 
#Defining a function called rename_files()    
    def rename_files():

        #**get file names from a folder**
        file_list = os.listdir(r"C:\Users\user\Desktop\webdev\prank")
#Knowing about current working directory
        saved_path = os.getcwd()
        print("Current Working Directory is " +saved_path)
#changing the directory
        os.chdir(r"C:\Users\user\Desktop\webdev\prank")

        #**for each file, rename filename**
#using For loop to change the name for each file name
        for file_name in file_list:
            os.rename(file_name,file_name.translate(None,"0123456789")
#saving back to current working directory
        os.chdir(saved_path)
#calling the function
    rename_files()

我认为您缺少右括号。

#importing the os library 
    import os 
#Defining a function called rename_files()    
    def rename_files():

        #**get file names from a folder**
        file_list = os.listdir(r"C:\Users\user\Desktop\webdev\prank")
#Knowing about current working directory
        saved_path = os.getcwd()
        print("Current Working Directory is " +saved_path)
#changing the directory
        os.chdir(r"C:\Users\user\Desktop\webdev\prank")

        #**for each file, rename filename**
#using For loop to change the name for each file name
        for file_name in file_list:
            os.rename(file_name,file_name.translate(None,"0123456789") ) <<<<<== Here
#saving back to current working directory
        os.chdir(saved_path)
#calling the function
    rename_files()
