Write A Python Program To Implement Function Using Positional Parameters

Hi Programmers, welcome to my blog, lets try to get python solution for write a python program to implement function using positional parameters.







Title :

Python Problem : Write A Python Program To Implement Function Using Positional Parameters


Description :

Positional Argument refers to function arguments whose position matters. To demonstrate thiw we take a function that takes three arguments string number and number. When the position of arguments change, you get an error message TypeError: unsupported operand type(s) for -: 'int' and 'str' Check the last two statements of the code. Last statement is incorrect and it throws error. Last second statement follows positional argument strictly. , nan


Code : 

def subtract_two_numbers(message, number1, number2):
    print(message, number1 - number2)

first = int(input("Enter first number : "))
second = int(input("Enter second number : "))
my_message = "Subtraction of two numbers is : "
subtract_two_numbers(my_message, first, second)  # This works
subtract_two_numbers(first, second, my_message)  # This fails with TypeError


output :
=============================
Enter first number : 8
Enter second number : 4
Subtraction of two numbers is :  4
Traceback (most recent call last):
        print(message, number1 - number2)
TypeError: unsupported operand type(s) for -: 'int' and 'str'


Conclusion :

Once you are done with reading the above code, open your python editor, try to write the program by yourself. This will improve your coding skills, try changing variable names, change operators and execute it.
