python - Split string in numbering

Question

Suppose i want my text file contains a list of commands:

1. eat, food
   7am
2. brush, teeth
   8am
3. crack, eggs
   1pm

How can we get:

"eat, food\n7am"
"brush, teeth\n8am"
"crack, eggs\n1pm"

I'm trying to use the classic split() with loops, but so far i haven't figured out how to get rid of the numbers.. Any suggestions?

Answer 1

使用regex和str.splitlines：

>>> import re
>>> s = """1. eat, food
   7am
2. brush, teeth
   8am
3. crack, eggs
   1pm"""
>>> lis = [re.sub(r'^\d+\.\s*', '', x).strip() for x in s.splitlines()]
>>> it = iter(lis)
>>> for x in it:
    print '{!r}'.format(x + '\n' + next(it))


'eat, food\n7am'
'brush, teeth\n8am'
'crack, eggs\n1pm'
