unable to call member function in class python

Question

I am on python 2.7 and trying to call a member function from another function which is located within same class.

class Foo:
     
     def bar(self):
         print 'correctly called'
         
     def baz(self):
         self.bar
    
  
a = Foo()
a.baz()

I went through this question and wrote a sample class as above, but still not able to print "correctly called" located in function bar. This may sound little noob but I think this is the only way to call a member function or am I doing anything wrong?

What I want

I simply want to call print statement located in bar function from another member function baz within same class.

To call a function, employ parentheses:

class Foo:
     def bar(self):
         print('correctly called')

     def baz(self):
         self.bar() # <-- ()

When you write self.bar, this is an expression evaluating to a function object. This is useful if you want to pass the function object to map and the like.

Call a method with ():

self.bar()

self.bar is the access to this object. Need the parentheses to actually call it.

@phihag sorry for late accepting. At first it asked me to wait for 12 minutes and after that I totally forgot. I have done it now. Thanks for efforts. – Dhruvify Dec 08 '15 at 12:42
