Converts a given string into an array of words.
|
|
|
|
- Use `re.findall()` with the supplied `pattern` to find all matching substrings.
|
|
- Omit the second argument to use the default regexp, which matches alphanumeric and hyphens.
|
|
|
|
```py
|
|
import re
|
|
|
|
def words(s, pattern = '[a-zA-Z-]+'):
|
|
return re.findall(pattern, s)
|
|
```
|
|
|
|
```py
|
|
words('I love Python!!') # ['I', 'love', 'Python']
|
|
words('python, javaScript & coffee') # ['python', 'javaScript', 'coffee']
|
|
words('build -q --out one-item', r'\b[a-zA-Z-]+\b') # ['build', 'q', 'out', 'one-item']
|
|
```
