Making decisions

Programs make decisions with if:

age = 15

if age >= 18:
    print("You can vote")
elif age >= 16:
    print("You can learn to drive")
else:
    print("Wait a little bit!")

To compare values:

Code	Means
`a == b`	equal (two `=`! one `=` is for variables)
`a != b`	not equal
`a < b`, `a <= b`	smaller, smaller or equal
`a > b`, `a >= b`	bigger, bigger or equal

Remember % from the maths exercise? n % 2 is the remainder when dividing by 2: it's 0 for even numbers.

Your mission

is_even(n) returns True if n is even, False otherwise.
describe_weather(temperature) returns:
- "cold" if the temperature is below 10
- "nice" from 10 to 25 (included)
