What is the python way to do this equivalent of this Perl line?

You can write

not (90 % 15) and print("yes")

If you use python 2 (and >= 2.6), you need to explicitly import print_function

from __future__ import print_function

This is needed because the right operand of the boolean and need to be an expression (and can not be a statement). In python2, print is a statement, thus you need to import the print function from python3, available in the __future__ module. Note that you could also use sys.stdout.write("yes\n") to achieve the same goal.

This would require `from __future__ import print_function`, wouldn't it? – ToonAlfrink May 25 '14 at 19:52
So this is using print(), a function from the future library, versus a print builtin? – GL2014 May 25 '14 at 20:18
Regular `print` in Python is a statement, and cannot be used as part of an expression. – tobyink May 25 '14 at 20:27

That exact line of code is also valid Perl, and reads better than the one with `!` and `&&` :) – hobbs May 26 '14 at 01:41
