Hi, I want to print out lock combination guesses, all as 4 digits with leading zeros as needed (0000, 0001, 0002, etc.), but I'm having trouble:

#!/usr/bin/env python3 #MoreOnLoops.py #pad lock guesser lockCombo = 1000 guess = 0000 while guess != lockCombo: guess += 1 if guess == lockCombo: print("After " + str(guess) + " guesses, the correct combo is " + str(guess)) break else: print("{:02d}".format(guess)) #print(str(guess) + " is not the correct combo. Trying next guess.") continue

Also, why is 100 not included in the output of the following loop:

for i in range(5, 100, 5):#start at 5, go up to 100 with increments of 5 print(i)

Output:
5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95

>>> guess = 0 >>> '{:0>4d}'.format(guess) '0000'

with f-strings in 3.6+

>>> guess = 0 >>> f'{guess:0>4d}' '0000'

because stop in range(start, stop, step) is not included

Excellent, but the first printed guess, 0000 did not appear, so I moved the guess incrementor to the else:

#pad lock guesser lockCombo = 1000 guess = 0 #'{:0>4d}'.format(guess)#for python 3 #f'{guess:0>4d}'#for python 3.6+ while guess != lockCombo: #guess += 1 if guess == lockCombo: print("After " + str(guess) + " guesses, the correct combo is " + str(guess)) break else: print('{:0>4d}'.format(guess)) #print('{:0>4d}'.format(guess) + " is not the correct combo. " + # "Trying next guess.") #print(f'{guess:0>4d}' + " is not the correct combo. " + # "Trying next guess.") #print(str(guess) + " is not the correct combo. Trying next guess.") guess += 1 continue

But as a result, the matching 1000 lock combo did not print out:

Output:
0000 0001 0002 0003 0004 0005 0006 0007 0008 0009 0010 0011 <output omitted> 0997 0998 0999 

How do I get it to include both the 0000 first guess and the 1000?

Is there a way to get it to print the 100, without having to change stop to 105?
