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_length函数作为key参数,这样就会按照元素长度进行排序。需要注意的是,sort函数会直接修改原始列表,而不是返回一个新的排好序的列表副本。总结 本文详细介绍了Python中的sort函数的用...

Sample Solution: Python Code: # Define a function 'sort_sublists' that sorts a list of lists by length and valuesdefsort_sublists(input_list):input_list.sort()# Sort the list by sublist contentsinput_list.sort(key=len)# Sort the list by the length of sublistsreturninput_list# Create ...
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 ...
