Hi 🙂🖐

Frist we need to kenow what is callback function

A callback function is a function that is passed to another function as an argument

examples


def myFunc():
    print('from myFunc function')


def call_func(callback_function):
    callback_function()


call_func(myFunc)

As you can see, call_func takes another function as an argument.

another example


def welcome1(name):
    print(f'welcome {name}')


def welcome2(name):
    print(f'Welcome : {name}')


def check_user(name, callback):
    if name == 'amr':
        callback(name)


check_user('amr', welcome1)
check_user('amr', welcome2)

In this example you can modify the function you are passing to another function, which is one of the advantages. of callback functions
