How to get index of a letter?

Question

I tried to find the index of a word using .index() but im not sure if thats how u find the index...? Can someone help please?
Edit: programming language is python

Answer 1

str has index AND find, list has only index.

In a string, you can find single letters, but also longer substrings (words) with both methods.

The difference is that find, if it *doesn't* find the substring, returns -1, and index will throw an error.

The problem, when you try to find, let's say, 'and' in a long string, you will also find the ands in words like hand, panda, sandy etc.

When I want to work with words in texts, I will first split the text into words, using the method 'split'.

'Hello World'.split() leads to ['Hello', 'World'].

Now you can easily find words using index, but single letters doesn't work anymore.

Answer 2

in python :
for strings use string.find("x")
for lists use list.index("x")
they return the position of x.
