It looks like constants are not really a concept that appears in Python. I was wondering why is that?

In other languages, such as Java, you can create constants (values that do not change after assignment). I'm wondering why Python does not really have this concept and how do Python developers deal with this if they have a value they don't want to be modified?

There's a programming convention (see the PEP 8 Style Guide) that constants should have all upper-case or MACRO_CASE names. That makes it easy to remember not to assign them again.

Another common practice is to locate all constants in a separate module.
