Get returned value of function in function which called it

Question

I am newbie in python, and I build two functions in which, I am calling second function with 1 parameters in first function and I am trying to access second function's returned data in first function.

def second_function(first_param):
    final = first_param + 50
    return final

def first_function():
    second_function(50)
    # trying to access second_function's returned data HERE
    print(second_function)

But it is not showing any returned data.

Any help would be much Appreciated. Thank You in Advance.

Answer 1

The problem here is that you are using print(second_function), so that will simply output the name of the function. Now, if you want to output the result of the function, you should do:

def second_function(first_param):
    final = first_param + 50
    return final

def first_function():
    output = second_function(50)
   
    print(output)

Answer 2

you could first put the returned value in a variable like this

def second_function(first_param):
    final = first_param + 50
    return final

def first_function():
    value = second_function(60)
    print(value )

or print the returned value with out using any variable

def second_function(first_param):
    final = first_param + 50
    return final

def first_function():
    print(second_function(50))

Answer 3

That's because second_function is an object in its own right. Try either of the following:

def first_function():
    out = second_function(50)
    # trying to access second_function's returned data HERE
    print(out)

def first_function_alternate():
    print(second_function(50))

What's happening when you do print(second_function) is that the computer is trying to print the value of the function itself, not what it returns. We can store this value to a variable (my first answer) or simply generate it on-the-fly (my second answer).

Answer 4

In Python, the returned data from a function will be assigned to a variable. So you would use:

my_value = second_function(60)

and the returned value would be stored in the variable my_value
