I almost moved, but I was looking at the print out again for this one:
print('%3d $%-13.2f $%-14.2f' % (count, payment, balance))
I can't understand why the $%-13.2f is pushed against the first
column, but the $%-14.2f is not. It seems like the first case ignores
the leading 0s and the second case doesn't not.
Let's break down the %-13.2f format code for example...
- Left justify (which was my original oversight)
13 Total field width, ie. 13 characters wide (default filler is space)
.2 Round to two decimal places -- that's 3 characters of the 13
(the decimal point plus the 2-digit fraction)
f The input is a floating point number
So the last column follows the 13-character wide second column...
(For illustration, I'm using '-' instead of the default space filler)
[-] [-----------] [------------] <-- showing field widths
-12 $123.45------- $15.00---------
Notice, the first field is right-justified by default.
(And that is not negative 12, the '-' is my pretend filler)
Helpful?
