Python: Check if a given value is a method of a user-defined class

Python module: Exercise-2 with Solution

Write a Python program to check if a given value is a method of a user-defined class. Use types.MethodType()

Sample Solution:

Python Code:

import types
class C:
    def x():
        return 1
    def y():
        return 1    
        
def b():
    return 2

print(isinstance(C().x, types.MethodType))
print(isinstance(C().y, types.MethodType))
print(isinstance(b, types.MethodType))
print(isinstance(max, types.MethodType))
print(isinstance(abs, types.MethodType))

Sample Output: 

True
True
False
False
False

Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

def tips_collect_dictionary(obj):
  inv_obj = {}
  for key, value in obj.items():
    inv_obj.setdefault(value, list()).append(key)
  return inv_obj
ages = {
  "Owen": 25,
  "Jhon": 25,
  "Pepe": 15,
}
print(tips_collect_dictionary(ages))

Output:

{25: ['Owen', 'Jhon'], 15: ['Pepe']}
