Re: [Numpy-discussion] How to use user input as equation directly

It is important to bear in mind where the code is being run - if this is something running on a researcher’s own system, they almost certainly have lots of other ways of messing it up. These kind of security vulnerabilities are normally only relevant when you are running code that came from

Re: [Numpy-discussion] padding options for diff

Matthew has made what looks like a very nice implementation of padding in np.diff in https://github.com/numpy/numpy/pull/8206. I raised two general questions about desired behaviour there that Matthew thought we should put out on the mailiing list as well. This indeed seemed a good opportunity to
