Answer:
def numCheck(num):
#this function takes a string representing a number as argument
#returns true if all digits are strictly increasing, false otherwise
for i in range(1,len(num)):
if num[i]<=num[i-1]:
return False
return True
num=input('Enter a six digit number: ')
while len(num)!=6 or not numCheck(num):
print('Incorrect value!! Plese enter again')
num=input('Enter a six digit number: ')
