如何判断字符串是否在Python中重复？就像你从[周期函数](http://en.wikipedia.org/wiki/Periodic_function)中取出一个sin或cos波并将其移到右边.由于它是完全周期性的,波浪最终将完美匹配...与此解决方案相似的数学算法只是惊人的.:)我希望我能给你+∞vvotes.(13认同)

Python while Loops: Repeating Tasks Conditionally In this quiz, you'll test your understanding of Python's while loop. This loop allows you to execute a block of code repeatedly as long as a given condition remains true. Understanding how to use while loops effectively is a crucial skill for...
pattern: a filter to choose which ones to display. For example to get a marine show, you can showtime(pattern='boat|fish|crab'): [alive-progress filtered spinners](img/showtime-marine-spinners.gif) You can also access these shows with the shorthands show_bars(), show_spinners(), and ...
