How to use internal python c funtions, from python code

[srinivas devaki]

Hi
I'm coming from this link (
https://groups.google.com/forum/#!topic/python-ideas/cBFvxq1LQHM), which
proposes to use long_to_decimal_string(), int_to_decimal_string() functions
for printing integers in different bases.

Now is there anyway i can use such internal functions from pure python
code, passing ctypes when the arguments are c datatypes.

For competitive programming purposes I really want to use those functions
for speed.
