为什么不呢？在print '\n'.join([str("*" * i) for i in range(1, 11)])

只需使用列表理解，使用换行符将行连接在一起。在

剥猫皮的方法不止一种。在这种情况下，任何一种解决方案都会奏效。Python针对列表理解进行了优化。另外，创建者Guido van Rossum讨厌映射、过滤器和reduce函数。。。在If Guido van Rossum, the author of the programming language Python, had got his will, this chapter would be missing in our tutorial. In his article from May 2005 "All Things Pythonic: The fate of reduce() in Python 3000", he gives his reasons for dropping lambda, map(), filter() and reduce(). He expected resistance from the Lisp and the scheme "folks". What he didn't anticipate was the rigidity of this opposition. Enough, that Guido van Rossum wrote hardly a year later: "After so many attempts to come up with an alternative for lambda, perhaps we should admit defeat. I've not had the time to follow the most recent rounds, but I propose that we keep lambda, so as to stop wasting everybody's talent and time on an impossible quest."

We can see the result: lambda, map() and filter() are still part of core Python. Only reduce() had to go; it moved into the module functools.

不要试图把一种语言当作另一种语言来使用。在
