What are constants in Python?

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics.

  • Python is an easy language to use and understand.
  • There are no complicated steps in Python.

Constants: Variables that hold a value and cannot be changed are called constants.

  • Constants are rarely used in Python – this helps to hold a value for the whole program.
  • Constants are usually declared and assigned for different modules or assignments.
#initialization of constants
PI = 3.14 
LAMBDA = 0.01

We initialize constants in capital letters as it helps us to write more semantic than static code.

main.py
constant.py
import constant
print(constant.PI)
print(constant.LAMBDA)
