Arguments

Part of the Fundamentals section of Coddy's Python journey — lesson 44 of 77.

An argument in a function is a value that you pass into the function when you call it. To add arguments to a function, we write them inside the parenthesis ():

def function_name(arg1, arg2, ...):
	code

We can name the arguments as we want, provided they follow the same naming rules as variables (e.g., they cannot be reserved keywords like def or if), and we can write as many arguments as we need.

To call a function and pass arguments to it, we write:

function_name(value1, value2, value3, ...)

Passing too many arguments to a function that is expecting fewer arguments will cause the program to fail

Example of usage:

def is_even(number):
	if number % 2 == 0:
		print(f"{number} is even")
	else:
		print(f"{number} is odd")

for i in range(15, 34):
	is_even(i)
for i in range(153, 219):
	is_even(i)

Here we have a function called is_even that accepts one argument called number and prints if the number is even or odd. Then we call the function twice: one time for all the numbers between 15 and 34, and the second time for all the numbers between 153 and 219.

Challenge

Easy

Write a program that takes two integers as input and calls a function to calculate and print their product.

Try it yourself

# Declare your function here
# print the result of a*b inside the function

a = int(input())
b = int(input())
# Call your function here with the arguments a and b
