Translate () takes exactly one argument (2 given) in python error

str.translate

requires dict

one that maps unicode ordinal numbers to other unicode ordinals (or None

if you want to remove a character). You can create it like this:

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

      

        
        
        
      

    

However, the easiest way to make a table is using a function str.maketrans

. It can take various arguments, but you need the third form, arg. We ignore the first two arguments as they are meant to map characters to other characters. The third arg is the characters you want 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"

      

        
        
        
      

    

This is how translation works:

yourstring.translate(str.maketrans(fromstr, tostr, deletestr));

      

        
        
        
      

    

Replace characters in fromstr with the character at the same position in tostr and remove all characters that are in deletestr. Fromstr and tostr can be empty strings, and the deletestr parameter can be omitted.

Instead of translating, why not just do this:

os.rename(file_name,''.join([i for i in file_name if not i.isdigit()]))

      

        
        
        
      

    

if you are using python 3.X try this: file_name.lstrip ()

    os.rename(file_name,file_name.lstrip(None,"0123456789"))

      

        
        
        
      

    

This function

str.translate(table[, deletechars])

      

        
        
        
      

    

only available for python 2.7. If you are using a higher version, you can use the following function, which is quiet and available in a higher version of python.

bytes.translate(table[, delete=b''])

      

        
        
        
      

    

Returns a copy of the bytes object, which removes any bytes that occur when the optional argument is removed

So, in your code, change this line of code

os.rename(file_name,file_name.translate(None,"0123456789"))

      

        
        
        
      

    

from

file_name_bytes = str.encode(file_name)
os.rename(file_name, file_name_bytes.translate(None, b"0123456789") 

      

        
        
        
      

    

If all you want to do is do the same thing that you did in Python 2 in Python 3, here's what I did in Python 2.0 to get rid of the punctuation marks and numbers:

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

      

        
        
        
      

    

Here's my Python 3.0 equivalent:

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

      

        
        
        
      

    

Basically, it says "translate nothing" (the first two parameters) and translate any punctuation marks or numbers to "None" (ie remove them).

Run the file using the python secret_message.py command. It works.

here is all the code:

import os

      

        
        
        
      

    

def rename_files (): # (1) get filenames from folder file_list = os.listdir (r "/ Users / archananagaraja / Desktop / AN_Personal / Udacity_Python / prank") print (file_list) current_dir = os.getcwd () print (" My current directory: "+ current_dir) os.chdir (r" / Users / archananagaraja / Desktop / AN_Personal / Udacity_Python / prank ") # (2) for each file, rename the file name for filename to file_list: os.rename (filename), file_name.translate (None, "0123456789")) rename_files ()
