Defining Your First Function
In earlier examples, like those in the "Conditional Statements" section, we often assigned different values to a variable just to verify our code was functioning correctly. This method can be cumbersome, especially as our code grows more extensive. A more efficient approach involves using functions. Here's the general syntax for defining a function:
Note
All lines of code within the function's body must have consistent indentation, whether it's 2 spaces, 3, 4, or another value.
For instance, let's craft a basic function that takes in two numbers (we'll call them a
and b
) and returns the square of their sum.
# Define function def sum_squared(a, b): return (a + b)**2 # Call function print(sum_squared(2, 3))
Success! Indeed, 2 + 3
equals 5
, and 5
squared is 25
.
