how to sort list of strings and numbers by numbers

Question

I want to sort this list by numbers, but I do not know how. I want to sort parenthesses by numbers, but if i do list.sort, it sorts by keys.

list = [("Max", 25), ("Lisa", 10), ("Jacob", 34)]
list.sort()
print(list)

how can i do it? Thanks.

Answer 1

The .sort() method (and the sorted() function) accept a key= parameter, the value of which is a function to use for getting the sorting criterion for a given item.

If you want to sort the tuples (not "parentheses") by the second item, pass a function that returns the second item.

list.sort(key=lambda item: item[1])
