Writing your own functions (1/5)

In the previous examples (for example in the Conditional statements Section) we assigned different values to a variable just to check if our code works as we need. It might be uncomfortable, especially when your code is becoming larger and larger. This can be solved by using functions. To define function use syntax:

123
def name_of_function(var1, var2...): body of function return smth
copy

For example, let's define a simple function, which receives two numbers and returns their sum squared.

123456
# define function def sum_squared(a, b): return (a+b)**2 # call function print(sum_squared(2,3))
copy
Tehtävä

Swipe to start coding

Define a function my_first_function with three arguments which returns the sum of tripled first number, doubled second and third and all raised to the second power. For example, for 5, 4, 3 it should return (5⋅3 + 4⋅2 + 3)^2 = 676. Test it on that numbers.
