REGEX formulating conditions

Just started learning python and regex. 

My regex:
\b\d+\s+([A-Za-z]* |[A-Za-z]*\s+[A-Za-z]*)\s+\D+..

using https://regex101.com/

string 1: https://i.imgur.com/XNuXftW.jpg (why does Beer has whitespaces while carrot/chocolate dont have?)

string 2https://i.imgur.com/nrl2FPB.jpg (adding further more of \s+[A-Za-z] in the capture group doesnt seem to be working anymore, WHY?)

string 3: https://i.imgur.com/qH0Z7Hi.jpg (same as string 2 problem)

my question is how do i continue to formulate such that it will encompass the above conditions? thank you

in the case that you need to test it yourself, i have provided the strings as below.

I guess the the space before "|" is the one causes it captures "beer " in string 1 case "Chocolate cake" does not happen as "beer " as it is matched with the second regex which is 

[A-Za-z]*\s+[A-Za-z]*

for string 2 [A-Za-z]\s+[A-Za-z] regex matches exactly two words

How about try below regex, modified from trincot

(?<=\s\s)(\w+\s)+(\w+)(?=\s\s)

Try this:

\d+\s+([A-Za-z ]*)\b *\D+

See on regex101.

You could use this regex, which takes advantage of look-behind (?<=) and look-ahead (?=) so it only captures the product names:

(?<=\s\s)\w+(?:\s\w+)*(?=\s\s)

See demo on regex101.com.

Use it with the g modifier.
