If you never need to do any string operations on it then you should
not be using a string.

Permitting leading 0s may make it harder to port Python 2 projects to
Python 3.
010 == 8 (Python 2)
010 == 10 (Python 3.x)
SyntaxError is very important for porting code.
So I'm -1 on permitting leading 0s for decimal numbers.
I think original question is for leading 0s for only 0.
Not for arbi

Let's just say that the word "number" has multiple meanings. Words with

The biggest use I have for decimal numbers that begin with 0 is in
credit card numbers, account numbers and the like where the first
check you do is 'does this thing have the correct number of digits'.
So far, all the examples I've been able to find in my code -- which
does this sort of stuff a lot

I'm curious about that statement.
I could see accepting input as you describe above, but I'm thinking
you'd want to *store* a postcode field.

Aligning numbers using spaces doesn't always align -- using zeros does.

The obvious solution is to use a fixed width font. If you're
inserting syntactical noise simply to maintain readability

Don't be noob ? ;)
Always remove leading zeroes ?
One case that comes to mind is ASCII art like code... where programmer may
want to align numbers for clearity:
0014324
0234545
345
0534543
^ That could be a problem but possibly solveable with spaces instead:
14324
234545
345

In Python 2, integer literals with leading zeroes are treated as octal, so
09 is a syntax error and 010 is 8.
This is confusing to those not raised on C-style octal literals, so in
Python 3 leading zeroes are prohibited in int literals. Octal is instead
written using the prefix 0o, similar to hex
37 matches
