I haven't touched Perl in more than 20 years... ... but I (routinely) miss something like:

   $variable = something() if sanity_check()

And

   do_something() unless $dont_do_that

Both work in python:

        variable = something() if sanity_check() else None


        do_something() if not dont_do_that else None

There exists a ternary if statement?

foo = something() if sanity_check else None

Can replace None with foo (or any other expression), if desired.

Additionally to the provided answers:

if sanity_check(): variable = something()

variable = sanity_check() and something

(but the standard python two line way is more readable unless it's a throwaway single use code, then whatever)
