I made a PR for another new method `np.char.slice_` here: https://github.com/numpy/numpy/pull/20694
Here is an excerpt of the PR message: There are numerous examples of string slicing being a fairly requested feature: - https://stackoverflow.com/q/70547027/2988730 - https://stackoverflow.com/q/39042214/2988730 - https://stackoverflow.com/q/40976714/2988730 - https://stackoverflow.com/q/64981711/2988730 - https://stackoverflow.com/q/31387047/2988730 - https://stackoverflow.com/q/69856133/2988730 - ... I stopped searching around here Given the existence of the `char` module, there is no reason not to include a basic slicing operation that can work cheaper than making views and copies of a string, or switching to pandas for this one feature. This PR introduces such a function. It's written entirely in python, and does its absolute best not to make a copy of any data. The original inspiration for this is my answer to the first question in the list above. I've added a couple of features since then, like the ability to have a meaningful non-unit step and the ability to set the length of non-unit-step chunks. Please let me know your thoughts about the value of something like this. Regards, - Joe
