Python Simple Tricks

1. Use local variables instead of module variables

A name like OS.LINESEP requires an interpreter to do two queries:

1) Find the OS to confirm that it is a module

2) Find the LINESEP variable in this module

Because the module is also a global variable, we consume more system resources. If you use a property in a function like this frequently, we recommend that you take a local variable alias for that property.

Variable lookup speed will be much faster-always look for local variables before looking for global variables.

This is also a let your A quicker way to Run a program: Replace the frequently used module property with a local reference.
