回文 palindrome Python 字符串反转string[::-1] Slice notation "[a : b : c]" means "count in increments of c starting at a inclusive, up to b exclusive". If c is negative you count backwards, if omitted it is 1. If a is omitted then you start as far as possible in the direction...
类图 下面是一个简单的Python类,用于判断一个字符串是否为回文: Palindrome- string s+is_palindrome() 在这个类中,我们定义了一个字符串变量s,并且有一个方法is_palindrome用于判断s是否为回文。 结语 通过本文的介绍,我们了解了回文数的定义和判断方法,并且学习了如何使用Python编程语言来判断一个字符串是否为回文。
