Alright, Currently, if given a string like such:
A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5,(F:0.6,G:0.7)H:0.8
I am using this:
child = Pstring[Pstring.find('(')+1:Pstring.find(')')]
To iterate through the string, and print out the inner parenthesis, and assign it to the variable 'child'
Now, my question is, how can I do the same for:
W:1.0,X:1.1(A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5,(F:0.6,G:0.7)H:0.8)Y:0.9
Which just simply contains an outside parenthesis to show that everything(except W and X) are children of Y
I currently get an output of 'child' as:
A:0.1,B:0.2,(C:0.3,D:0.4
Whereas what I want the code to do is to first parse through the outside parenthesis, and grab the inner ones first, then work on the outside last.
Thanks!
If you just want the contents of the inner parentheses, you can use re.findall() with the following regular expression:
\(([^()]*)\)
For example:
>>> import re
>>> s = 'W:1.0,X:1.1(A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5,(F:0.6,G:0.7)H:0.8)Y:0.9'
>>> re.findall(r'\(([^()]*)\)', s)
['C:0.3,D:0.4', 'F:0.6,G:0.7']
Explanation:
\( # literal '('
( # start capturing group
[^()]* # any characters except '(' and ')', any number
) # end capturing group
\) # literal ')'
re.findall() returns the contents of the capturing group for each match.
