Question

Is there a way that I could index a letter in a string and have Python return an integer? I.e., if I have a string s='inn and suites', can I get n1=1, n2=3, and n3=5, referring to their position? Indexing doesn't work because it only "indexes" the first occasion of the character.

Answer 1

Because strings are indexed, you can use a slice that starts right after the last instance of a letter. In this way, you can use a loop or recursion to find every instance of a letter.

Answer 2

```
>>>
>>> s='inn and suites'
>>> enns = []
>>> for ndx, char in enumerate(s):
if char == 'n':
enns.append(ndx)

>>> enns
[1, 2, 5]
>>>
```
