Python For循环获取索引

Question

我正在编写一个简单的Python for循环来抛出字符串中的当前字符.但是,我无法获得角色的索引.这是我拥有的,有没有人知道在循环中获取字符的当前索引的好方法？

 loopme = 'THIS IS A VERY LONG STRING WITH MANY MANY WORDS!'

 for w  in loopme:
    print "CURRENT WORD IS " + w + " AT CHARACTER " 

Answer 1

使用该enumerate()函数生成索引以及要循环的序列元素:

for index, w in enumerate(loopme):
    print "CURRENT WORD IS", w, "AT CHARACTER", index 

Answer 2

你想遍历字符或单词吗？

对于单词，您必须先拆分单词，例如

for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index

这将打印单词的索引。

对于绝对字符位置，您需要类似的东西

chars = 0
for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index, "AND AT CHARACTER", chars
    chars += len(word) + 1
