Accessing the index in 'for' loops? 17 answers

使用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

Do you want to iterate over characters or words?

For words, you'll have to split the words first, such as

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

This prints the index of the word.

For the absolute character position you'd need something like

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
