But you don't add two values. you add two strings. If you
want numbers you must convert the strings.
Why? At least -

You see the picture? Pythons designer made the

they use the _same_ operator (+) for number _addition_
and string _concatenation_, which is, imho, cumbersome.
And ``+`` means also list/tuple concatenation

The code is a very good starting point for me! I already
managed to change it and I see I need to make it a bit more robust.
I think, the only thing you have to look at - is
the congruence of the regex-based filter rule and the text.
suppose
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 = {}
for el in mylist:
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
P.S.
file.close()

What I first though was if there was possible to make a filter such as:
Apples (apples)
(ducks) Ducks
(butter) g butter
Try something like:
import re
text = Some text that can span some lines.
Apples 34
56 Ducks
Some more text.
filters = {apples:
