A number of people have mentioned the quality of error reporting as a
strike against Python.  Can any of these people provide a concrete
example of what they are talking about?  With source code, and a
misleading or confusing error message?

I've never had any problem understanding or using Python error
messages.  They're much like Perl errors: you get an error message, a
code location, and a backtrace.  Sometimes one wants a little more
information in order to make a full diagnosis, so for one Python
project I wrote a tiny utility to get backtraces with local variable
values, which I can then print out and put in the application log


The fact that I develop most of my Python with a command line to hand,
in which I can type at any point to grovel around the code
and data with the debugger, makes Python errors very much easier for
me to deal with than Perl ones.  I dare say there are command line
tools analogous to this, built in to Perl, but I've never found them.
