# Another example using functions and return code:

import random

# Defining the function:
def get_answer(answer):
    if answer <10:
        return "The answer is smaller than 10"
    elif answer == 10:
        return "The answer is 10."
    else:
        return 'The answer is greater than 10'

# Generating a random number, using that random number to define a variable by using it as an argument in the funtion,
# and printing the result:
random_number = random.randint(1, 20)
result = get_answer(random_number)
print(result)

# The 3 lines above can be rewritten to a single line:
print(get_answer(random.randint(1, 20)))

# And the check to see if the code is working as it should:
print(f"(It is {random_number})")
