Apr 21, 2010 · I am trying different ways to create a real constant in Python and perhaps I found the pretty solution. Example: Create container for constants >>> DAYS = Constants( ... MON=0, ... TUE=1, ... WED=2, ... THU=3, ... FRI=4, ... SAT=5, ... SUN=6 ... ) Get value from container >>> DAYS.MON 0 >>> DAYS['MON'] 0 Represent with pure python data structures

Dec 30, 2024 · In Python, constants are variables whose values are intended to remain unchanged throughout a program. They are typically defined using uppercase letters to signify their fixed nature, often with words separated by underscores (e.g., MAX_LIMIT).

In this tutorial, you'll learn how to define Python constants by using variable names with all letters in uppercase.

There are no constants in Python, the way they exist in C or Java. You can imitate them by functions: def FOO(): return "foo" You can wrap the function call in a property, and thus make it look like a variable: class Const: @property def FOO(self): return "foo" CONST = Const() # You need an instance if something == CONST.FOO: ...

Mar 3, 2021 · There is no predefined type for a constant variable in Python. But we can use pconst library for that. Installation: Below are some examples which depict how to use constants in python.
