Here is some example code that produces an error:
class Test(object):
def greet():
print "Hello"
t = Test()
t.greet()
TypeError: greet() takes no arguments (1 given)
Ok. That makes sense. t.greet() is a "bound method", so something
automatically relays the instance object to greet(), and since greet()
is defined with no parameters-->Error.
Hmmm...I know from testing several examples that if I call a function
that's defined inside a class, and I use the class name preceding the
function call, then I have to send the instance manually. So, based
on that error message, I'll just call the method using the class name
and not send the instance object:
Test.greet()
TypeError: unbound method greet() must be called with Test instance as
first argument (got nothing instead)
