A return statement consists of the return keyword followed by an optional return value. The return value of a Python function can be any Python object.The python return statement is used to return the output from a function. We learned that we can also return a function from another function. Also, expressions are evaluated and then the result is returned from the function.
Can a variable equal a function in Python : Essentially, if you set a variable equal to your function, the variable will be equal to what you return. The variable x will be whatever you return from the function. However, if you don't have a return function in your function definition, it will automatically set x equal to None . Hope this helps!

However, creating a variable with the const keyword is recommended to assign the function as the function expression always remains constant.
A function defined with a return type must include an expression containing the value to be returned. In this example, the return statement initializes a variable of the returned type. The variable answer is initialized with the int value 30. The type of the returned expression is checked against the returned type.
