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
for elem in enumerate(loopme), then use elem[[0] for the index value and elem[1] for the character, but that is just more cumbersome.enumerate() can be used on any sequence. It doesn't create a map, it simply keeps a counter. Every time the for construct asks for the next element, it in turn asks the wrapped sequence for the next item, then returns the value of the counter together with that next value from the wrapped sequence, then increments the internal counter.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
wis the current character, not word.
