How to create a function object from an ast.FunctionDef node?

Question

I am trying to understand the process by which python code gets executed. Suppose the source has a function definition. Using ast.parse(), I parse it into an as

Answer 1

In case the function is under a class, below code will help - import ast

txt = """
class MyClass():
  def foo(x, y=2):
      z = x*y + 3
      print("z is", z)
      return z**2
"""

tree = ast.parse(txt, mode='exec')
code = compile(tree, filename='blah', mode='exec')
namespace = {}
exec(code, namespace)
val = "foo"
dict_item = namespace["MyClass"].__dict__.items()
for x,y in list(dict_item):
  if val == x:
    print(x)
    print(y)
    print(type(x))
    print(type(y))
