idi nenu rasindi python lo ... mostly regex is same irrespective of language.. 

 

m = re.findall("((http:|https:)//[^ \<]*[^ \<\.])",line)

 

m is temp variable 

re is regex module 

dot is operator

findall is attribute/class/function/sub-routine in the 're' module

"" quotes madhyalo logic

line is the string u pass & wants to try to find regex match logic in quotes against the line

 

quotes ""  lo unnadi logic ardam ayinda kaleda ?

to understand regex... read this http://www.regular-expressions.info/refquick.html

 

C# lo You don't need a regex for URLs, use System.Uri class for this. E.g. by using Uri.IsWellFormedUriString method for this:

bool isUri = Uri.IsWellFormedUriString(url, UriKind.RelativeOrAbsolute);
