Calculate the average of three numbers

avg = (num1+num2+num3)/3

Display a variable inside an f string and round it to only have 2 decimals, like with money. (the end result looks like this: 1000.00)

monthly_payment = 1000.0000
print(f'The monthly payment is {monthly_payment:.2f}.')

Display a large number and add commas in-between every 3 digits. (the end result looks like this: 1,000,000,000)

large_number = 1000000000
print(f'{large_number:,}')

Display a value using a minimum field width. This is useful for spacing in a cli or gui. (the end result looks like this: The number is ________99)

number = 99
print(f"The number is {number:10}")

Align the text when a field width is specified. The < can be substituted for a > or ^ to align right or center respectively.

number = 40
print(f"{number:<10}")
