modified regexp and documentation

Browse Source 
I think there is no use of using space literal match (/s) in the pattern. So I removed it and updated the snippet and it's document accordingly. Please review it and let me know if I am wrong.

Converts a string to camelcase.
Break the string into words and combine them capitalizing the first letter of each word, using a regexp, `title()` and `lower`.
Identify one or more groups containing the pattern with `-` or `_` using regexp `r"(_|-)+"` and replace the pattern with a `" "` (space literal) using `re.sub` method. Apply `title()` method on the obtained string to Capitalize the starting letter and lower the other letters of every word in the string. Finally, remove the spaces in the string using `replace()` method
```py
import re
def camel(s):
s = re.sub(r"(\s|_|-)+", " ", s).title().replace(" ", "")
s = re.sub(r"(_|-)+", " ", s).title().replace(" ", "")
return s[0].lower() + s[1:]
```
