String formatting with fixed width

[Alexander Eisenhuth]

Hello alltogether,

is it possible to format stings with fixed width of let's say 7 character. T
need a floating point with 3 chars before dot, padded with ' ' and 3 chars after
dot, padded with '0'.

Followingh is my approach'21.100'

But there are missing ' '. How can I get that? (For bigger numbers than 999 they
might be cut: 1021 -> 021)

Thanks,
Alexander

... return "%7.3f" % (x % 1000.0)
... ... print f(x)
...
9.900
99.900
999.900
999.900

You can use something like this:' 21.100'


However, this will only make the string at *least* 7 long. If the
length of the number exceeds this, you'll end up with it even longer;
for instance:

'2123123121.100'

From your example about 'cutting' it, it looks like you just might be

able to take the last 7 chars from it using [-7:]

...
... print f(x)
...
9.900
99.900
999.900
999.900

.... but (unfortunately?):

You don't say what you want to do about negative numbers, so this may or
may not be significant.

Thanks for your fast reply. I'm fine with your "%7.03f" solution. (negatives are
not significant)
