Variables in Python do not need to be declared. Each variable must be assigned a value before use. The variable will not be created until the variable is assigned a value.
In Python, a variable is a variable, it has no type. What we call "type" is the type of the object in memory pointed by the variable.
The equal sign (=) is used to assign values to variables.
The left side of the equal sign (=) operator is a variable name, and the right side of the equal sign (=) operator is the value stored in the variable.
Python3 has 6 most commonly used data types, which are:
Numbers (numbers)
String(String)
List(List)
Tuple(Tuple)
Sets (set)
Dictionaries (dictionary)
Among the six standard data types of Python3:
Immutable Data (3): Number, String, Tuple;
Variable data (3): List, Dictionary, Set ).
