Converts a given string into an array of words.

• Use re.split() with a supplied pattern (defaults to non-alpha as a regexp) to convert to an array of strings.
• Use filter() in combination with None to remove any empty strings.
• Omit the second argument to use the default regexp.

import re

def words(str, pattern = '[^a-zA-Z-]+'):
  return list(filter(None, re.split(pattern, str)))

words('I love Python!!') # ['I', 'love', 'Python']
words('python, javaScript & coffee') # ['python', 'javaScript', 'coffee']
