Variables in Python are programmer provided (hopefully user friendly) labels that store a value. Python is a dynamically typed language, which means that the variable is not tied to a particular type of data. For example, if you have a variable named “x” it can hold numeric values like (123123) or a string value like (“car”) or a boolean value like (True).
1) Types of Variables
Here is a Table containing the various data types available in Python
|Data Type||Description||Example Values|
|Integers||Numbers without decimal points. Can be any size. It is constrained only by the memory in your computer.||1 100 10000 1000000000000000000000000000000000000000000|
|Floating Point Numbers||Numbers that require a decimal point. Can use scientific notation (eg .4e5 which is the same as 40000.0)||1.0 2.20 4.2022323234 1.2e-4 (same as .00012)|
|Boolean||Can hold one of 2 values: True or False||True False|
|Strings||A sequence of characters. Are delimited by either single quotes (‘) or double quotes (“)||‘Hello’ “Hello” ‘Apollo 11’ ‘John\’s computer’ “John\’s computer”|
2) Create an Integer
x = 100
3) Create a Float
x = 100.23
4) Create a Boolean
x = True
5) Create a String
x = "Hello"
