As you can see there no compiling error, because the syntax is correct,
you'll eventually get a runtime error like this:
>>> import t
>>> c = t.MyClass()
>>> c.func2()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: func2() takes no arguments (1 given)
That's because you left out the "self" argument in the definition of
"func2()". This version is correct:
--
def func1():
print "hello"
class MyClass(object):
def func2(self):
func1()
c = MyClass()
c.func2()
--
[EMAIL PROTECTED] ~ % python tcorrect.py
hello
