.reverse()这个方法的返回值就是空 一般使用的时候直接 list.reverse()print(list)就行 该方法没有返回值，但是会对列表的元素进行反向排序。所以直接print（list）来查看反向排列的情况就好reverse原地逆反list你执行list.reverse()print(list)
Traverse each number in the list by using for...in loop. Check the condition i.e. checks number is divisible by 2 or not – to check EVEN, number must be divisible by 2. If number is divisible by 2 i.e. EVEN number, remove the number from the list. To remove the number from ...

If you are using Python 2.x then you can import print function as below: 1 2 3 from __future__ import print_function Using loop Here, for loop is used to iterate through every element of an array, then print that element. We can also use while loop in place of for loop. Below...
This tutorial implements an approach to printing Strings In Reverse Dictionary Order Using Trie. Trie is a data structure with a tree representation. It is in ordered form and provides an efficient approach for string retrieval. It has nodes and edges like a tree data structure. To solve the ...
