Python 单词字母顺序不变且全部倒排
2018-07-20 来源：open-open
设计一个函数，任何语言都可以，实现以下功能：
一个句子，将句子中的单词全部倒排过来，但单词的字母顺序不变。eg. this is a real world输出结果为：world real a is this
笔者用Python实现如下：
#! /usr/bin/env python
# -* -coding:utf-8-*-
def str_reverse(str):
str_dst =str.split()[A1]
str_dst.reverse()[A2]
return str_dst
if __name__ == ‘__main__’:
for str_out in str_reverse(raw_input(‘plz input ur sentence:’)):
print str_out,
Python is Python!
[A1]以空格为分隔符，将单词取出放入list中。
关于split():
string.split(s[, sep[, maxsplit]])
Return a list of the words of thestring s. If the optional second argument sep is absent or None, the words areseparated by arbitrary strings of whitespace characters (space, tab, newline,return, formfeed). If the second argument sep is present and not None, itspecifies a string to be used as the word separator. The returned list willthen have one more item than the number of non-overlapping occurrences of theseparator in the string. If maxsplit is given, at most maxsplit number ofsplits occur, and the remainder of the string is returned as the final elementof the list (thus, the list will have at most maxsplit+1 elements). If maxsplitis not specified or -1, then there is no limit on the number of splits (allpossible splits are made).
The behavior of split on an emptystring depends on the value of sep. If sep is not specified, or specified asNone, the result will be an empty list. If sep is specified as any string, theresult will be a list containing one element which is an empty string
