Is there any library like 'msvcrt' to use cross-platform?

Question

Try to make listening commands input to work in console on any system. Is there any library to use methods in cross-platform way?

Example:

try:
import msvcrt
else:
import getch as mscvrt

and then use:

msvcrt.getwch()

but this wasn't work cause lack of repeating methods /=
Any suggestions or advices? Someone handle this before? Or I need to make full OS oriental part of code?
