+1 Options are options, arguments are arguments. An optional argument is not an option. It is an argument that can be left out. On Wed, 2010-06-02 at 12:42 +0200, Antoine Pitrou wrote: > On Wed, 2 Jun 2010 01:49:18 -0700 (PDT) > Michele Simionato wrote: > > > > Notice that optparse is bas

Yes it is; d[i:j] is equal to "give me the array from the d[i] to d[j - 1]", and if you omit i and j then the i and j are respectively assumed as 0 and len(d) - 1. On Wed, Jun 2, 2010 at 8:01 PM, pmz wrote: > On 2 Cze, 19:56, geremy condra wrote: >> On Wed, Jun 2, 2010 at 10:40 AM, pmz wrote: >
