Read Method

[Gribouillis]

What I need to find out if it is possible to know is whether a method of a particular class exists?

Try this for example

>>> class A:
...     def foo(self): pass
...     def bar(self): pass
... 
>>> help(A)

Output:
class A(builtins.object)
 |  Methods defined here:

 |  Data descriptors defined here:

 |  
 |  __weakref__
