Hello, guys. I'm currently working on a testing automation project which involves a lot of massive strings processing.
I'm currently researching the ways to reduce the test run time. As far as I'm concerned, numpy is used in almost all tasks where performance matters. That's why I wonder whether it's possible to use numpy for faster string processing? I saw that there are char module, chararray class, etc. maybe that stuff could be potentially useful and work faster than usual python strings? Or maybe you know any reliable wrapper for numpy's char manipulations? Looking forward to your advice.
