Hi all, I wanto to print just the first 5 characters of a string,
why this doesn't work (py3.1)?
print("{0:5}".format("123456789"))
123456789
I know I could use print("123456789"[:5]), yeah it's a stupid
example, but isn't format for string formatting?
The width field of the format is a *minimum* width. So you can use
it to force padding, but not truncation. If you need the string
truncated, just use slicing, as you already showed.
Or use the .precision specifier:
py> "{0:.5}".format("123412341234")
'12341'
{0:5.5} has the same effect. See
http://docs.python.org/library/string.html#format-string-syntax
Whoa! i never realized you could use precision on strings. I knew
(the hard way) that it won't work on ints, but I never thought to try it
on strings.
Thanks.
