I fear that won't work.

If it doesn't work in cron, that probably means, PATH is not set 
properly in your cron environment. And if PATH is not set properly, 
searching it explicitely won't work either.

If rm works when evoked directly in a cron script but not via a python 
script, you may need to export the PATH in your cron script.
