Question

The “dir()” function in python retrieves all attributes for a class. I was wondering if there was a similar function that returns only user defined functions? Thanks!

Answer 1

If you want to tell a builtin from a user-defined function I’d use the types module.
For instance:

>>> def hello():
...     print("hi")
... 
>>> import types
>>> type(hello) is types.BuiltinFunctionType
False
>>> type(hello) is types.FunctionType
True

Then it depends on what you want to do.You could use list comprehensions to check all attributes of a class and keep only those that turn out to be true.

[ x for x in dir(yourclass) if (type(x) is types.FunctionType) ]

Hope it helps.
