- Why are Python strings immutable?
- =================================
- There are several advantages.
- One is performance: knowing that a string is immutable means we can
- allocate space for it at creation time, and the storage requirements
- are fixed and unchanging. This is also one of the reasons for the
- distinction between tuples and lists.
- Another advantage is that strings in Python are considered as
- "elemental" as numbers. No amount of activity will change the value 8
- to anything else, and in Python, no amount of activity will change the
- string "eight" to anything else.
