Teacher solution

num = int(input("Enter a number: "))

while num > 0:    # while, we will ask for factorials
  factorial = 1
  while num > 0:  # calculate the factorial
    factorial *= num
    num -= 1
  print(factorial)
  num = int(input("Enter a number: "))

Teacher solution

# Version with ord() and chr()
character = ord(input("Enter a character (will crash if you enter more than one)"))

if ord('a') <= character <= ord('z'):
    print('The letter', chr(character), 'is lowercase')
elif ord('A') <= character <= ord('Z'):
    print('The letter', chr(character), 'is uppercase')
elif ord('0') <= character <= ord('9'):
    print(chr(character), 'is a number')
else:
    print(chr(character), 'is a symbol')
