+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.
+
+```py
+import re
+
+def words(str, pattern = '[^a-zA-Z-]+'):
+  return list(filter(None, re.split(pattern, str)))
+```
+
+```py
+words('I love Python!!') # ['I', 'love', 'Python']
+words('python, javaScript & coffee') # ['python', 'javaScript', 'coffee']
+```
