Regular Expression to match numbers in square brackets in python

Question

I need to match and return the string index of numbers which are contained in square brackets. Example string:

Gabrilovich and Markovitch [11, 12] propose a method to use conditional random fields [6] as a training process.....

Here I would like to extract the index of any given number like 11, 12 or 6 in the above case using regular expressions. I am trying

pattern = re.compile(r'[/11/]') # for 11
result =  re.search(pattern, text, flags=0)
print result.start()

However with this I am not getting desired results. Note: I would need a solution for matching the exact number I want, not any given number within brackets.

Answer 1

use this regex expression (\[[,\d\s ]*)11([,\d\s ]*\]) for retrieving all the 11's in the text
