leading zero number formatting

[RedSkeleton007]

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'

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

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

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

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?

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

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