The correct function depends on the language, but for Python the usual choice is sorted() or the list method .sort() for alphabetical order.

Quick answer

  • sorted(my_list) returns a new list in alphabetical order.
  • my_list.sort() sorts the existing list in place.

Example

python

names = ["banana", "apple", "cherry"]

print(sorted(names))   # ['apple', 'banana', 'cherry']
names.sort()
print(names)           # ['apple', 'banana', 'cherry']

If you meant JavaScript

JavaScript uses array.sort(), and for proper alphabetical sorting of strings it is common to use a compare function or lowercase comparison.

Short version

If you just want the alphabetical sort function in Python, use sorted() or .sort().
