use a function in another function in Python

In this Tutorial, we'll learn how to use a function in another function.

First, we need to create a simple function that we'll use in another function.

def fun_1():
    return "Hello fun_1"

Now, let's create another function core and using fun_1 inside of it.

def core():

    #call the function
    f1 = fun_1()

    #print
    print(f1)

Finally, let's call core function and see the result.

#call 'core' function
core()  

result:

Hello fun_1
