My string module doesn't have maketrans or translate functions

[Lamb]

Hi all,
I'm really new to python and trying to figure out the basic rule and settings of it. I'm using python 3.3 and I was trying this code in python:

import string
s = "string. With. Punctuation?"
out = s.translate(string.maketrans("",""), string.punctuation)

And I got the following error:
Traceback (most recent call last):
File "C:/Python33/trials/ls.py", line 5, in <module>
out = s.translate(string.maketrans("",""), string.punctuation)
AttributeError: 'module' object has no attribute 'maketrans'

So I used the following to see functions inside string
e=dir(string)['ChainMap', 'Formatter', 'Template', '_TemplateMetaclass', '__builtins__','__cached__', '__doc__', '__file__', '__initializing__', '__loader__', '__name__', '__package__', '_re', '_string', 'ascii_letters', 'ascii_lowercase', 'ascii_uppercase', 'capwords', 'digits', 'hexdigits', 'octdigits', 'printable', 'punctuation', 'whitespace']

It doesn't have translate(), maketrans(), rstrip() and a whole lot of otherthings. What's the problem?

Thanks!

Thanks! It worked! But why didn't I see functions : translate(), maketrans(), rstrip(), etc. listed when I called print(dir(string))?

Because they're not in the string module any more - they're methods on
str (and bytes). Try checking out dir(str) - str being the class of
your basic Unicode string now, rather than being the type of a string
of bytes - and you should see them all.

The string module is effectively dead. Many functions were deprecated
back in 2.6, maketrans in 3.1, just use string methods instead.

The string module is effectively dead.

It's not dead, it's pining for the fjords.

But seriously, the string module holds a collection of useful string
constants and the Template class.
