How do I do this without string.count(), because it is listed as deprecated in Python v2.7.3 documentation?

I am unable to find what I should use instea

    Use str.count() - it's not listed as deprecated.

    (Python 2.7.3, Python 3.2.3 - both have no notes about being deprecated).

    >>> "test".count("t")
    2
    

    I'll presume you meant string.count() - which is depreciated in favour of the method on string objects.

    The difference is that str.count() is a method on string objects, while string.count() is a function in the string module.

    >>> "test".count("t")
    2
    >>> import string
    >>> string.count("test", "t")
    2
    

    It's clear why the latter has been deprecated (and removed in 3.x) in favour of the former.
