Extracting words between delimiters [] in python -

By the string below, I want to extract words between delimters [] such as 'Service', 'service', '9991 ',' 1.22 ':

  str =' mysrv event generated event name [service current], category [ Service]  
   
  
 
 
 
 
 Div class = "post-text" itemprop = "Text"> 
 First of all, avoid using  str  as a variable name.  str  already has a meaning in Python and you can confuse people by defining it to do something else. 
 
 It is said that you can use the following regular expression: 
 <>  & gt; & Gt; & Gt; Import re & gt; & Gt; & Gt; Print Refund (R '[[[^]] *) \]', S) ['Service On', 'Service', '9991 ',' 1.22 ']  

It works as follows:

 \ [Matching anything except a catalyting group [^]] one match, * match with zero or more] Close the capturing group is an optional regular expression : 
 
  r '[[ It works like this ]
