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

For-else construct useful when searched for something and find it:

# For example assume that I need to search through a list and process each item until a flag item is found and 
# then stop processing. If the flag item is missing then an exception needs to be raised.

for i in mylist:
    if i == theflag:
        break
    process(i)
else:
    raise ValueError("List argument missing terminal flag.")
