A lot of sysadmins, devops and product integration people using perl for quick filters so they don't have to learn awk or sed with:
cmd | perl -e 'stmt;stmt;stmt;stmt;stmt' | cmd
You cannot do the same thing in python easily and that is an issue as you mentioned. Another issue is that the whitespace is creating havoc in bigger team and multi-platform projects where people work with many different environments and editors and small whitespace changes are sometimes not so easy to catch and can have code changing impact.
PERL has the write hundred ways quality, but in enterprise you can agree on standard way to write and then a larger team can be more productive in PERL than Python. PERL is also so much better at language embedding if you need to implement core routines in C.
On the other hand Python excels in the new to scripting, small (5) cohesive team market. They got that pretty much cornered now.
