`cmp_to_key` 函数是 Python `functools` 模块中的一个工具,用于将一个老式的比较函数(即 cmp 函数)转换为一个可用于 `sorted`、`min`、`max` 等函数的键函数(key function)。这很有用,特别是在迁移旧代码或使用需要比较两个元素并返回它们大小关系的函数时。 在Python 2 中,`sorted` 和其他排序方法既支...
Take a look at the previous output. We have created my_list1 and my_list2, two lists of strings that contain the same elements, but not in the same order. Let’s see how to compare these two lists using several methods!Example 1: Compare Two Lists With ‘==’ Operator...
you are likely to get the date information as a string. It is helpful to convert the string to a datetime object since it will allow you to do more advanced functions. In today’s article, I will discuss and show examples of datetime objects in python. Specifically, I will show how to...
Again, here, we use the set() function to obtain unique sets of elements fromlist2andlist3. Then, we use the-operator to find differences between these sets. Lastly, we print the results usingfstringslike in previous case. only_in_list2=set(list2)-set(list3)# find unique elementsonly...

It's because Python sorts the counts as strings (because they are), not as numbers. And in string sorting, "7" is greater than "17". To solve that, you have to cast the string to int in the sorted() call. lst = [['Rabbit', '7'], ['Dog', '3'], ['Bird', '...
