Python - logical evaluation order in “if” statement

Question

In Python we can do this:

if True or blah:
    print(\"it\'s ok\") # will be executed

if blah or True: # will raise a NameError
    print(\"it\'s not ok\")
         


        

Answer 1

With the or operator, values are evaluated from left to right. After one value evaluates to True, the entire statement evaluates to True (so no more values are evaluated).

• It's a feature of the language
• There is nothing wrong with using its functionality
