Python For loop get index

Question

I am writing a simple Python for loop to prnt the current character in a string. However, I could not get the index of the character. Here is what I have, does anyone know a good way to get the current index of the character in the loop?

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

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

Use the enumerate() function to generate the index along with the elements of the sequence you are looping over:

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
