The else branch in the if statement doesnt work properly (python)

I expect the result will be 'Only accepted the numbers between 1 ~ 6' when I input some number like '9', but the else statement is actually ignored and get through.

main.py

def select_class():

  while True:
    try:
      class_number = int(input('Select number below\n (1)12:00~13:30\n (2)13:35~15:05\n (3)15:45~17:15\n (4)17:20~18:50\n (5)18:55~20:30\n (6)20:25~22:00\n---------------\n'))
      class_text = input('Leave a comment if you have\n')
  
  if re.match(r'[1-6]', class_number):
    if class_number == 1:
      class_hr, class_min = '00', '00'
      return class_hr, class_min, class_text
    elif class_number == 2:
      class_hr, class_min = '01', '35'
      return class_hr, class_min, class_text
    elif class_number == 3:
      class_hr, class_min = '03', '45'
      return class_hr, class_min, class_text
    elif class_number == 4:
      class_hr, class_min = '05', '20'
      return class_hr, class_min, class_text
    elif class_number == 5:
      class_hr, class_min = '06', '55'
      return class_hr, class_min, class_text
    elif class_number == 6:
      class_hr, class_min = '08', '30'
      return class_hr, class_min, class_text
  else:
    print('Only accepted the numbers between 1 ~ 6')
    return class_number
except ValueError:
  pass

terminal:

$ py main.py

Select number below

(1)12:00~13:30
