user_input = input("请输入一个字符串:") reversed_string = user_input[::-1] print(f"反转后的字符串为:{reversed_string}") reverse_string() 这个简单的程序使用切片操作反转字符串,非常直观。 结论 以上几个示例展示了Python在实现简单有趣的项目方面的强大能力。通过这些项目,初学者可以在实践中巩固编程知识,同时享受编程带来的乐趣。希望这些示...

position = string.find(str, last_position+1) ifposition ==-1: returnlast_position last_position = position print(test('hi how are you hello world, hello yoyo!','hello')) 结果: 28 11. 给定一个数 a,判断一个数字是否为奇数或偶数。
If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError. On Unix, GNU readline is used if enabled. The prompt string, if given, is printed without a trailing newline before reading. >>> 注意这里笔者的Python是3.3的,根据上面的描述可以很清楚的看到,input函数是从标准输...
Unless it is absolutely necessary, you should not obtain a string from user input or another process and pass it toDbgPrint. If you do use a string that you did not create, you must verify that this is a valid format string, and that the format codes match the argument list in type ...

When we developed Universal Print, our goal was to create a single print solution that meets people where they are and "just works—from every app, on every device. Today, we're taking a new step tow...
