Question

Python: How do I convert an int to its string representation with a set number of digits?

Answer 1

+1 A:

Use str.zfill(width)

The URL for zfill is http://docs.python.org/library/stdtypes.html#str.zfill. The % or format techniques are preferred.

Answer 2

+10 A:

Maybe I'm misinterpreting the question, but this should work:

my_string = "%05d" % 100

Huh. Assumed that was part of the args to print. Nope. God, it's a beautiful language.

@deworde: It's even better if you read through a tutorial. Seriously. What tutorial are you using?

@S.Lott I'm looking at http://docs.python.org/tutorial/introduction.html#strings right now.And that doesn't tell you it's in there, and when it gives you an example in the reference notes, always uses print.

deworde 2010-08-27 08:20:16

@deworde: Thanks. There's a "See Also" section that's relevant. You might want to use http://diveintopython.org/native_data_types/formatting_strings.html instead.

S.Lott 2010-08-27 10:24:38

@S.Lott Yes, that would be the reference notes I referred to, but as I said, always uses print in the examples.Also, they're, as usual, in a style that means you have to know what you're looking for before you start looking. My favourite line, "The effect is similar to the using sprintf() in the C language". I mean technically, that should have been helpful, but it does rather make an assumption.

@S.Lott Cheers for the link, though. V. helpful.

Answer 3

+1 A:

This should work too:

`100`.zfill(5)

Answer 4

A:

If you're using Python 3, the str.format method is preferred. It was introduced in Python 2.6. (Alas, my work system is at 2.4 (and I'm not permitted to upgrade), so I can't construct and test an example.)

Answer 5

+1 A:

print('{0:0=5d}'.format(100))
# 00100


    use the 0th positional argument to format
   /  fill character is '0'
  /  / desired width of formatted string
 /  / /
{0:0=5d}

For more, see the docs.
