how to use alignment and leading zeros here (within the f-string)?

Question

a = 10
b = 20

expected output:
000010 000020

#using f-string, <, and 06

# how to put 6 ({a:06}, {b:06}) leading zeros for each num. :
# f"{a:<20} {b:<20}"

Answer 1

06 means that your number is filled up with zeros and the whole thing spreads on 6 letters. The number itself is right-aligned (otherwise you wouldn't have zeros on the left side), but the thing as a whole is not really aligned anymore...

Is this about a space between the columns? Either you can fill up the f-string with spaces like {} {} - or you could use two f-strings and use the str justification methods, for example:

print(f'{a:06}'.ljust(8), f'{b:06}'.ljust(8))

So this would mean that you rjust a number on a space of 6, filling up with zeros, and then you take this thing and ljust it on a width of 8.

Answer 2

I just tried this, seems to work! (Or maybe I haven't understood what you're aiming at?)

a=2
b=4
print(f'{a:06} {b:06}')

Answer 3

I want to use both leading zeros and left alignment, not just leading zeros. HonFu
