Cost
Missing spaces can increase costs
This code insight counts one violation each time :
- following operators are not surrounder with at least one space: =, += , -=, == , < , > , != , <> , <= , >= , in , not in , is , is not, and , or , not.
- following elements are not followed by at least one space : comma, semicolon, colon (except slice operator)
Why you should care
- Always surround these binary operators with a single space on either side: assignment ( = ), augmented assignment ( += , -= etc.), comparisons ( == , < , > , != , <> , <= , >= , in , not in , is , is not ), Booleans ( and , or , not ).
Additional for Highlight :
- Always put a whitespace immediately after :
- comma
- semicolon
- colon (except when using as slice operator)
Business Impacts
It is recommended to avoid these in order to ensure the code is more readable and cost effective.
