How do I create a constant in Python?

Question

Is there a way to declare a constant in Python? In Java we can create constant values in this manner:

public static          


        

Answer 1

A tuple technically qualifies as a constant, as a tuple will raise an error if you try to change one of its values. If you want to declare a tuple with one value, then place a comma after its only value, like this:

my_tuple = (0 """Or any other value""",)

To check this variable's value, use something similar to this:

if my_tuple[0] == 0:
    #Code goes here

If you attempt to change this value, an error will be raised.
