I've said that I've found the Python programming language uncompelling. As a language, my impression is that it's a better language than perl, but I still use perl from time to time, but I don't use Python. The main way I use perl is from the command line to run one-off scripts. The one thing I knew about Python from the early 1990s when I first heard about it, until 2009, when I decided to try using it, was that indentation was syntactically significant, which means you can't write one-liners (even though the one line could contain 500 or more characters) like you can with braces and semicolons. perl -e 'while (<>) { ... }' is very convenient when trying to do something that would be too complicated when using pure shell constructs.
