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
