Converts a string to camelcase.

• Use re.sub() to replace any - or _ with a space, using the regexp r"(_|-)+".
• Use str.title() to capitalize the first letter of each word and convert the rest to lowercase.
• Finally, use str.replace() to remove spaces between words.

from re import sub

def camel(s):
  s = sub(r"(_|-)+", " ", s).title().replace(" ", "")
  return ''.join([s[0].lower(), s[1:]])
