Python: Naming Variables

Python: Naming Variables

一

1. only use ordinary letters, numbers, or underscores in variable names
2. need to start with a letter or underscore

table6
table_6

二

can’t use reserved words or built-in identifiers

三

pythonic way to name variables is to use all lowercase letters and underscores to separate words, called snake case.

my_height = 170
my_lat = 40
my_long = 100
