You can do something like this:
def decorate_functions(decorator, module):
Function = type(lambda:0), type(len)
for name, obj in module.__dict__.iteritems():
if isinstance(obj, Function):
setattr(module, name, decorator(obj))
Example:
>>> def trace(f):
... def decorated(*args, **kwargs):
... print 'calling', f.__name__
... return f(*args, **kwargs)
... return decorated
...
>>> import math
>>> decorate_functions(trace, math)
>>> math.log(math.tan(math.pi/4))
calling tan
calling log
