Using getattr

class Person(object):
def __init__(self, first_name, last_name):
self.first_name = first_name
self.last_name = last_name
def say_hello(name):
print "Hello, {}!".format(name)
adrienne = Person("Adrienne", "Domingus")
>>> adrienne.first_name
>>> getattr(adrienne, ‘first_name’)
>>> getattr(adrienne, 'say_hello')
<bound method Person.say_hello of <Person object at 0x10640de50>>
>>> method = getattr(adrienne, 'say_hello')
>>> method("Someone else")
Hello, Someone else!

Putting it to work: generalizing method calls

if http_method == 'post':, data=data)
elif http_method == 'put':
requests.put(url, data=data)
method = getattr(requests, http_method)
method(url, data=data)
