How do I add a % symbol to my Python script

Question

Here is my code. I need to add a percent symbol at the end of the print string. I can't get this figured out.

total = 0
counter = 0
while True:
    score = int(input('Enter test score: '))
    if score == 0:
        break
    total += score
    counter += 1
average = total / counter
print('The average is:', format(average, ',.3f'))

Answer 1

The probably best way would be to just use the percent format type:

format(average, '.1%')

# or using string formatting:
'{:.1%}'.format(average)

This already multiplies the average by 100 and will also show a percent sign at the end.

>>> average = .123
>>> print('The average is: {:.1%}'.format(average))
The average is: 12.3%

Answer 2

print('The average is: ' + format(average, ',.3f') + '%')
