regex - Find Hyperlinks in Text using Python (twitter related)

Question

How can I parse text and find all instances of hyperlinks with a string? The hyperlink will not be in the html format of <a href="http://test.com">test</a> but just http://test.com

Secondly, I would like to then convert the original string and replace all instances of hyperlinks into clickable html hyperlinks.

I found an example in this thread:

Easiest way to convert a URL to a hyperlink in a C# string?

but was unable to reproduce it in python :(

Answer 1

Here's a Python port of Easiest way to convert a URL to a hyperlink in a C# string?:

import re

myString = "This is my tweet check it out http://tinyurl.com/blah"

r = re.compile(r"(http://[^ ]+)")
print r.sub(r'<a href="1">1</a>', myString)

Output:

This is my tweet check it out <a href="http://tinyurl.com/blah">http://tinyurl.com/blah</a>
