Hi, I'm trying to solve an exercise, a beginners one but I have a question. So the exercise sounds like this:
Define a string s = ’colorless’. Write a Python statement that changes this to ’colour- less’, using only the slice and concatenation operations. So I did wrote this: *1)s = 'colorless' 2)ss = s[:4] + 'u' + s[4:] 3)print(ss) *I do not understand something. So on the second line, the slicing lasts from the start of the s string to the forth character. But from were does the counting start? 0 or 1? From this code it's obvious that it starts from one, but how, strings counting doesn't start from 0? If I do len(s) i get 9 but if I do s[9] I get an error, out of range. Can please someone clear me this indexing thing? It's so frustrating and confusing. * *
