def sort_by_length(element): (tab)return len(element) fruits = ["apple", "banana", "orange", "kiwi"] fruits.sort(key=sort_by_length) print(fruits)在这个例子中，我们定义了一个名为sort_by_length的函数，该函数的作用是返回字符串的长度。然后，我们使用sort函数并传递了sort_by_l...

Since we passed the len function as key, the strings are sorted based on their length.Before we wrap up, let’s put your knowledge of Python list sort() to the test! Can you solve the following challenge? Challenge: Write a function to sort a list of strings by their length. For ...
