While learning Python I stumbled upon a conditional statement that doesn't have a full condition and I can't seem to figure out the use.

if number: print ("2")

What is being compared to number? I can't seem to figure out when it's true and when it's false.

Infinitylsx

This basically just checks if the value of *number* isn't Null. If number has a value (doesn't matter what value except Null or None) it prints "2". – Tehc Jan 27 '17 at 15:41
Should be true if it's not equal to 0. Right? – Shark Jan 27 '17 at 15:41

no, could be `None`, empty list/tuple/dict, everything that is "falsy" – Jean-François Fabre Jan 27 '17 at 15:41
