Answer 1

Try calling help on an object to find out about it.

>>> foo = [1, 2, 3]
>>> help(foo.append)
Help on built-in function append:

append(...)
    L.append(object) -- append object to end

Answer 2

import inspect

def foo(a,b,x='blah'):
    pass

print(inspect.getargspec(foo))
# ArgSpec(args=['a', 'b', 'x'], varargs=None, keywords=None, defaults=('blah',))
