This is where a nested for loop works better. The first loop (parent loop) will go over the words one by one. The second loop (child loop) will loop over the characters of each of the words. words=["Apple","Banana","Car","Dolphin"]forwordinwords:#This loop is fetching word from...
with less regard for backwards compatibility than is the case for new releases in the 2.x range. The most drastic improvement is the better Unicode support (with all text strings being Unicode by default) as well as saner bytes/Unicode separation. ...

Baldric had been a town guard for years, breaking up fights and catching thieves and helping the elderly cross the street. When the Empire arose and moved him to HR, he dragged prisoners to staff meetings and hauled corpses away without thinking much of it. Law and order was better than ...
The older API is mainly still there for backwards compatibility, and you won’t cover it in this tutorial. There’s also a fair amount of redundancy in the subprocess module, meaning that there are various ways to achieve the same end goal. You won’t be exploring all variations in this...
Guido van Rossum (the original creator of the Python language) decided to clean up Python 2.x properly, with less regard for backwards compatibility than is the case for new releases in the 2.x range. The most drastic improvement is the better Unicode support (with all text strings being ...

这段代码的可视化执行在autbor.com/deletingloop进行。 名单里好像还剩下'yello'。原因是当for循环检查索引2时,它从列表中删除了'mello'。但是这将列表中所有剩余的条目下移一个索引,将'yello'从索引3移到索引2。循环的下一次迭代检查索引3,它现在是最后一个'hello',如图 8-2 中的所示。那根'yello'字符串浑...
Think of how you can loop through a string or array of characters backwards to produce a new string. def FirstReverse(str): # code goes here return str # keep this function call here print FirstReverse(raw_input()) 二、解法:切片
