I think, the only thing you have to look at - is
the congruence of the regex-based filter rule and the text.

Try something like:

Apples 34
56 Ducks

First try, probably there are better ways to do it, and it's far from
resilient, it breaks in lot of different ways (example: more than one
number in one line, number with text on both sides of the line, etc.)
I have divided the data munging in many lines so I can see what's
happening, and you can
list.txt is a file that contains the following lines:
Apples 34
Bananas 10
Oranges 56
>>> file = open("list.txt","r")
>>> mystring = file.read()
>>> mystring
'Apples 34 \nBananas 10\nOranges 56 '
>>> mylist = mystring.split('\n')
>>> mylist
['Apples 34 ', 'Bananas 10', 'Oranges 56 ']
>>> mydict =
16 matches
