regex in python, can this be improved upon?
- by tipu
I have this piece of code that finds words that begin with @ or #,
p = re.findall(r'@\w+|#\w+', str)
Now what irks me about this is repeating \w+. I am sure there is a way to do something like
p = re.findall(r'(@|#)\w+', str)
That will produce the same result but it doesn't, it instead returns only # and @. How can that regex be changed so that I am not repeating the \w+? This code comes close,
p = re.findall(r'((@|#)\w+)', str)
But it returns [('@many', '@'), ('@this', '@'), ('#tweet', '#')] (notice the extra '@', '@', and '#'.
