%s says to suck a string out of the parameter tuple and insert it here.
%15s says to right-justify the string in a field 15 columns wide.
%-15s says to left-justify the string in a field 15 columns wide.
for s in ('x','xx','xxx','xxxx'):
print "%15s***%-15s***" % (s,s)
With %15s or %-15s, the ENTIRE string is inserted, even if it is longer
than 15 characters. If you want the string limited to at MOST 15
characters, use "%-15.15s".
