Answer 1

import sys
import time

c=':'
sec = 0
min = 0
hour = 0

#count up clock

while True:
for y in range(59):                                                 #hours
    for x in range (59):                                            #min
        sec = sec+1
        sec1 = ('%02.f' % sec)                                      #format
        min1 = ('%02.f' % min)
        hour1= ('%02.f' % hour)
        sys.stdout.write('\r'+str(hour1)+c+str(min1)+c+str(sec1))   #clear and write
        time.sleep(1)
    sec = 0
    sys.stdout.write('\r' + str(hour1) + c + str(min1) + c + '00')  #ensure proper timing and display
    time.sleep(1)
    min=min+1
min = 0
sys.stdout.write('\r' + str(hour1) + c + str(min1) + c + '00')      #ensure proper timing and display
time.sleep(1)
hour=hour+1
