Try importing them and handle the exceptions that are thrown if they don't 
exist. Either wrap the import directly in a try:except: block, or define a 
function using __import__:

>>> def modAvailable(name):
	try:
		__import__(name)
	except ImportError:
		return 0
	return 1

>>> print modAvailable('sys')
1
>>> print modAvailable('junk')
0

int month(char *p){return(124864/((p[0]+p[1]-p[2]&0x1f)+1)%12)["\5\x8\3"
"\6\7\xb\1\x9\xa\2\0\4"];} // Who said my code was obscure?
