Python constants
Constants
In Python, a constant is a variable whose value remains unchanged throughout the program. Constants are usually defined in all capital letters so that they can be easily identified.
In Python, there is no built-in support for constants. However, you can define constants in your program by assigning a value to a variable and then not changing the value of the variable.
Here is an example of how to define and use constants in Python:
"""
Constants -> Python doesn't support constants,
but we use the uppercase letters to show
that it is a constant
"""
WEBSITE_HOST = 'https://solomonmarvel.com'
print(WEBSITE_HOST)
# code example
PI = 3.14159265
def calculate_area(radius):
return PI * radius * radius
radius = 10
area = calculate_area(radius)
print(f"The area of a circle with radius {radius} is {area}")
