3. Generator Function Checker

Write a Python program to check if a given function is a generator or not. Use types.GeneratorType()

Sample Solution:

Python Code:

import types
def a(x):
    yield x
        
def b(x):
    return x

def add(x, y):
    return x + y

print(isinstance(a(456), types.GeneratorType))
print(isinstance(b(823), types.GeneratorType))
print(isinstance(add(8,2), types.GeneratorType))

Sample Output:

True
False
False

For more Practice: Solve these Related Problems:

• Write a Python program that defines both a generator function and a normal function, calls each, and uses types.GeneratorType to print whether the returned object is a generator.
• Write a Python script that creates a generator using a generator expression and then checks its type with types.GeneratorType, printing a confirmation message.
• Write a Python function that takes a function as input, calls it, and then verifies whether the output is a generator, using types.GeneratorType for the check.
• Write a Python program that stores multiple functions in a list, calls each, and prints whether each function's output is a generator using the types module.
