Python | Time matches

Question

Hey!
I want to print all the possible time matches in HH:MM format:
00:00
00:01
00:02
NN:NN
12:58
12:59
Help me, please!

Answer 1

Ah, thanks to Lisa I think I know now what you try to do :-D

this should work (with Python 3.6+ - otherwise use zfill() from the first answer to achieve the 2-digit numbering):

for i in range(12):
for j in range (60):
print(f"{i:02d}:{j:02d}")

Answer 2

f-Strings is a newer way of string formatting in python

i have written some string formatting demo some time ago:

here you can find a very detailed description of string formatting possibilities:

Answer 3

You could use a nested loop.

• The outer loop iterates through the hours [0; 12]
• The inner loop iterates for each hour through the minutes [0; 59]

Answer 4

I'm not sure if I got the question, but what works for example:

hour = 3
minute = 5
print(str(hour).zfill(2) + ":" + str(minute).zfill(2))

outputs:
03:05

Answer 5

Martin Ed Yes, that's what I had in mind 😀

Nice formatting! 😀

Answer 6

Martin Ed, that worked fine - just had to change 12 to 13 to get all the possible matches up to 12:59 (for i in range(13))!
Thanks a lot!
but, please, would you explain to me the print parameters you added:
f
{i:02d}

Answer 7

i is the variable name 02d formats, for example i = 3 to 03 in the f-string

Answer 8

Gotcha! Thanks a lot, guys!
