How to iterate over each string in a list of strings and operate on it's elements

Question

Im new to python and i need some help with this.

i need to com

Answer 1

Try:

for word in words:
    if word[0] == word[-1]:
        c += 1
    print c

for word in words returns the items of words, not the index. If you need the index sometime, try using enumerate:

for idx, word in enumerate(words):
    print idx, word

would output

0, 'aba'
1, 'xyz'
etc.

The -1 in word[-1] above is Python's way of saying "the last element". word[-2] would give you the second last element, and so on.

You can also use a generator to achieve this.

c = sum(1 for word in words if word[0] == word[-1])
