See more:

extract strings from a string

string = '[ {"roll" : context("345") }, {"roll" : context("344")) } ]'

Expected output,
['roll', context("345"), 'roll', context("345")]

What I have tried:

Python

import re
re.findall(r'"([^"]*)"', string)
Present Output, ['roll', '345', 'roll', '344']

Expected output,  
['roll', context("345"), 'roll', context("345")]

Unclear. That's what you asked for.
I recommend you get something like Expresso to develop and test your Regular Expressions.

Solution 2

Something like:

Python

>>> string = '[ {"roll" : context("345") }, {"roll" : context("344")) } ]'
>>> string2 = string.replace('{','')
>>> string3 = string2.replace('}','')
>>> string4 = string3.replace(':',',')
>>> string4
'[ "roll" , context("345") , "roll" , context("344"))  ]'
>>>
