Intermediate Python

Starting from the initial code:

my_list = [5, 7, 34, 5, 3, 545]

big_numbers = []
for num in my_list:
    if num > 10:
        big_numbers.append(num)

print(big_numbers)

python bignums.py

[34, 545]

We pull out the middle four lines, indent them, put def big(numbers): in front and add return big_numbers to the end, paying careful attention to the indentation of the return statement. Finally, we update the variable name used in the function to match the argument name numbers:

def big(numbers):
    big_numbers = []
    for num in numbers:
        if num > 10:
            big_numbers.append(num)
    return big_numbers


my_list = [5, 7, 34, 5, 3, 545]

large_numbers = big(my_list)

print(large_numbers)

python bignums.py

[34, 545]
