Regex error: 'NoneType' object has no attribute 'group'
#1
Hello,

In the code below, I receive the error listed in the title of my question.  I'm trying to extract the substring between asterisks: 'Some text**string1;string2;string3**'.  If I change the print statement to print(result.group(1)), I get the correct results (string1;string2;string3), but when I assign it to the variable result as I have in the code and print result, I get the error message.  How do I use .group() correctly during the result variable assignment?


last_validation_comment_lst = validation_comment_lst[-1]
last_validation_comment_string = ''.join(last_validation_comment_lst)
result = re.search('\*\*(.*)\*\*', last_validation_comment_string).group(1)
print(result)
