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

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']}
