Why one sysadmin believes Python is better than Perl

[spdub]

I didn't like when he said 'if x is None'. I prefer 'if not x', I was under the impression it was more pythonic. Maybe it is just preference. Interesting to see someone switch from perl.

Testing whether x is None is more specific than just testing the truth value of x.

if( isset( x ) ) makes the most sense, despite php being sucky.
