What data types does python have?

Python basic data types

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 does not have a type. The "type" mentioned in the code is the type of the object in memory pointed to by the variable.

The equal sign (=) is used to assign values ​​to variables

The left side of the equal sign is the variable name, and the right side is the value to be stored in the variable. For example: a = 100; b = 100.0 #Floating point variable; c = 'python' #String variable

Multiple variable assignments

python allows Assign multiple variables. For example: a = b = c = 1; the three variables point to the same memory location.

You can also specify multiple variables for multiple objects. For example: a,b,c = 1,2, "python"

There are six standard data types in python:

Number (number)

string (character String)

List (List)

Tuple (Yuanzu)

Sets (Collection)

Directionary (Dictionary)

Data type characteristics:

Immutable data (4): Number, String, Tuple, Sets

Variable data (2): List, Directinary
