Which type of arrangements can I give to sort function in python

Question

I want to sort a list of name by the length of each name and not by alphabet order.

Answer 1

As Abhay mentioned you can use sort(), that will do the sorting "in-place", so the initial list will be changed. As sort() does not give a return value, it should not be used in combination with print. So 2 steps are needed: sort, print.
- There is also an other possible solution by using sorted(). Using this, a new list will be created, the initial list will stay unchanged.
- Additionally there is an option for both versions to define whether sorting will be done ascending (default) or descending (using reverse= True) sorted() gives a return value, so it will print correctly. There is only one step needed: sort + print.

inp = 'This is Major Tom to ground control'.split(' ')
print(sorted(inp, key=len, reverse=True))

Answer 2

sort(key=len)
