# Datatypes in python

# standard datatypes: integers, floating, string, boolean
# advanced datatypes: lists, tuples, dictionaries, sets

# Variable naming conventions
# camelCase
# snake_case
# pascalcase
#
# Shouldn't start with a number
# Shouldn't have spaces between words
# Can start with _ but not with any other character such as "-:{}"etc
# Choose a meaningful name for your varaible (recommended)

# Comments in python
# Single line comments
# Inline comments
# Block comments

# This is my integer : Single line comment
my_int = 10 # Value 10 is stored in my_int container : Inline comment

# E.g. my_int and My_int are 2 different variables
# False and false are 2 different things in python
