Variables and constants for Python

The interpreter executes the Python process: (python3,c:/test.py)

1: Start the Python interpreter (in memory).

2: Read the c:/test.py content from the hard disk into memory (this step is the same as the text editor).

3: Execute code that reads into memory.

What is a variable?

Variable: Change

Volume: A Status Level = 1 levels: Variable Name 1: value

PS: Defines a variable that stores data as a variable value.

Variable names and variable values are just a binding feature.

The variable name itself is not stored worth the function.

The 3 important components of a variable definition are:

ID Type: type name: Value

is the comparison id = = is the comparison value

Constant = unchanging Quantity There is no specific definition of constants in Python, usually with uppercase variable names, just a hint effect.
