>>> id(eggs) # eggs now refers to a completely different list. 44409800 如果两个变量引用同一个列表(就像上一节中的spam和cheese)并且列表值本身发生了变化,那么这两个变量都会受到影响,因为它们都引用同一个列表。append()、extend()、remove()、sort()、reverse()等列表方法原地修改它们的列表。 Python...
['Code', 'Favtutor', 'Machine Learning', 'Students', 'Studies', 'java', 'python', 'tutoring'] To do this in descending order, we will use the Reverse as a hyperparameter for the order by which you want to sort your list, False is ascending and True is descending. Example: str...
Note: Python sorts strings lexicographically by comparing Unicode code points of the individual characters from left to right. That’s why the uppercase I appears before the lowercase e. To learn more about some of Python’s quirks when ordering strings, check out the tutorial How to Sort ...

Run Code Output ['a', 'gh', 'abc', 'wxyz'] len is a built-in function that returns the length of a string. 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...
See the respective Python code below.def mycmp(a, b): # defining compare function if a[1] > b[1]: return 1 elif a[1] < b[1]: return -1 else: return 0Then, we use the sorted() function with the key parameter set as follows to specify the comparator via the cmp_to_key() ...
