Python 3 regex to split list of items?

I'm reading in some data in the form a list of items, space separated. Each item has a name, which may be one or more words, and a quantity which can either be a single integer or a fraction of integers.

Ex.

'12 Spruce Log 4/5 Water 3 Orange 3/18 Oak Plank'

I want this split into the following list:

['12 Spruce Log', '4/5 Water', '3 Orange', '3/18 Oak Plank']

Here is my Python regex:

import re
re.findall(r'\d+(/\d+)?\D+', "12 Spruce Log 4/5 Water 3 Orange 3/18 Oak Plank")

This produces the following result, which is obviously not right:

['', '/5', '', '/18']

What is the proper regex here?

So here is what i came up with:

/(?:\d+\/\d+|\d+)\s(?:[[:word:]]+\s*){1,2}(?=\d|$)/g

You can try this:

import re
s = '12 Spruce Log 4/5 Water 3 Orange 3/18 Oak Plank'
new_s = re.split('(?<=[a-zA-Z])\s(?=\d)', s)

Output:

['12 Spruce Log', '4/5 Water', '3 Orange', '3/18 Oak Plank']

Or, just using re.findall:

new_list = [i[:-1] if i.endswith(' ') else i for i in re.findall('[\d\/]+\s[a-zA-Z\s]+(?=\d)|[\d\/]+\s[a-zA-Z\s]+(?=$)', s)]

Output:

['12 Spruce Log', '4/5 Water', '3 Orange', '3/18 Oak Plank']
