Translate() Takes Exactly One Argument (2 Given) In Python Error

import os import re def rename_files(): # get the files from dir file_list=os.listdir(r'C:\OOP\prank') print(file_list) saved_path=os.getcwd() print('current w

Solution 1:

str.translate requires a dict that maps unicode ordinals to other unicode oridinals (or None if you want to remove the character). You can create it like so:

old_string = "file52.txt"
to_remove = "0123456789"table = {ord(char): None forcharin to_remove}
new_string = old_string.translate(table)
assert new_string == "file.txt"

However, there is simpler way of making a table though, by using the str.maketrans function. It can take a variety of arguments, but you want the three arg form. We ignore the first two args as they are for mapping characters to other characters. The third arg is characters you wish to remove.

old_string = "file52.txt"
to_remove = "0123456789"
table = str.maketrans("", "", to_remove)
new_string = old_string.translate(table)
assert new_string == "file.txt"

Solution 2:

Higher versions in Python use this :

eg: oldname= "delhi123"remove="1234567890"table=str.maketrans("","",remove)    
oldname.translate(table)    

Overall solution for your query:

import os    

defrename_file_names():    
    file_list=os.listdir(r"C:\Users\welcome\Downloads\Compressed\prank")    
    print (file_list)    
    saved_path=os.getcwd()    
    print("current working direcorty is"+saved_path)    
    os.chdir(r"C:\Users\welcome\Downloads\Compressed\prank")    
    remove="123456789"    
    table=str.maketrans("","",remove)    
    for file_name in file_list:    
        os.rename(file_name,file_name.translate(table))    


rename_file_names()    

Solution 3:

Change os.rename(file_name,file_name.translate(None,"0123456789")) to os.rename(file_name,file_name.translate(str.maketrans('','',"0123456789"))) and it will work.

Solution 4:

If all you are looking to accomplish is to do the same thing you were doing in Python 2 in Python 3, here is what I was doing in Python 2.0 to throw away punctuation and numbers:

text = text.translate(None, string.punctuation)
text = text.translate(None, '1234567890')

Here is my Python 3.0 equivalent:

text = text.translate(str.maketrans('','',string.punctuation))
text = text.translate(str.maketrans('','','1234567890'))

Basically it says 'translate nothing to nothing' (first two parameters) and translate any punctuation or numbers to None (i.e. remove them).

Solution 5:

import os

def rename_files():
    #1get file names from folder
    list_files = os.listdir(r"C:\Personal\Python\prank")
    print(list_files)
    saved_path = os.getcwd()
    print(os.getcwd())
    os.chdir(r"C:\Personal\Python\prank\")

    #2foreach file, rename filename
    remove = "0123456789"
    table= str.maketrans("","",remove)
    for file_name in list_files:
        os.rename(file_name, file_name.translate(table))

    os.chdir(saved_path)

rename_files()
