Python RegEx find and add to beginning

Question

Just learning RegEx in Python, and got stuck on this case:

str = '''
Here are some order bullets:
i. Foo
ii. Bar
iii. Baz
iv. YOLO
...
x. LOL
'''

How do I get to this:

str = '''
Here are some order bullets:
- i. Foo
- ii. Bar
- iii. Baz
- iv. YOLO
...
- x. LOL
'''

You can use this regex in MULTILINE mode:

>>> print re.sub(r'(?m)^([a-zA-Z0-9]+\.)', r'- \1', str)

Here are some order bullets:
- i. Foo
- ii. Bar
- iii. Baz
- iv. YOLO
...
- x. LOL
