题目描述:
Write a function that takes in a string of one or more words, and returns the same string, but with all five or more letter words reversed (Just like the name of this Kata). Strings passed in will consist of only letters and spaces. Spaces will be included only when more than one word is present. Examples:
spinWords( "Hey fellow warriors" ) => returns "Hey wollef sroirraw" spinWords( "This is a test") => returns "This is a test" spinWords( "This is another test" )=> returns "This is rehtona test"
题目为反转字符串中单词长度大于等于5的单词。代码如下:
先使用split()通过空格将每一个单词分给开来。 * split()函数split(str=”“, num=string.count(str)) 以str为分隔符截取字符串,如果num有指定值,则仅截取num个字符串。 * str – 分隔符,默认为所有的空字符,包括空格、换行(\n)、制表符(\t)等。 * num – 分割次数。分割后的字符串转换为了list。 字符串实现反转的方法: * 使用字符串切片:result = s[::-1] * 使用列表的reverse():l = list(s) result = “”.join(l.reverse())””最后再使用join
将每一个单词连接为一个字符串输出。
def spin_words(sentence): # Your code goes here sentence = sentence.split(" ") return " ".join([i[::-1] if len(i) >= 5 else i for i in sentence])
