Question
What advantages do tuples have over lists?
Advertisements
Solution
The advantages of tuples over the lists are as follows:
- Tuples are faster than lists.
- Tuples make the code safe from any accidental modification. If data is needed in a program that is not supposed to be changed, then it is better to put it in ‘tuples’ than in ‘list’.
- Tuples can be used as dictionary keys if it contains immutable values like strings, numbers, or other tuples. ‘Lists’ can never be used as dictionary keys as ‘lists’ are mutable.
