>>> a = 'aaa,bbb'

>>> a_regex = re.compile(r'(a{3}),(b{3})')

>>> if (re.match(a_regex,a)): print True

else: print False

 

True

its a pythonic approach. 

"import re" anna kada....antey... importing regular expression (re) module into python namespace and using couple of attributes/methods likes re.compile & re.match 

if you are looking for just regex expression, highlighted it. 

want to learn more about regex... here you go. https://docs.python.org/2/library/re.html

and want to test your regex against a certain strings , here you go http://www.regexr.com/

@posiedon - what is {3} bro?

{m} Specifies that exactly m copies of the previous RE should be matched; fewer matches cause the entire RE not to match. For example, a{6} will match exactly six 'a' characters, but not five.

@posiedon - what is {3} bro?

IT expects exactly 3 characters. You can set range like {2,4} matches 2 3 or 4 characters \S is any character except space

okka sari paina ichina links saduvu man.... sadivi Qs adugu....w/o doing ur HW, dont ask others to spoon feed you

then use 

{m,} Specifies that atleast m copies of the previous RE should be matched; fewer matches cause the entire RE not to match. For example, a{3,} will match atleast three 'a' characters or more, but not two, .
