🐍 I don’t like NumPy
｢ NumPy is all about applying operations to arrays. When the arrays have 2 or fewer dimensions, everything is fine. But if you’re doing something even mildly complicated, you inevitably find yourself with some operation you want to apply to some dimensions of array A, some other dimensions of array B, and some other dimensions of array C. And NumPy has no theory for how to express that ｣
