My interpretation of the point in the blog post was that explicitly spelling out variable names makes APIs and the underlying code much more accessible to a wider audience. Sure, there'll be a subset of users of these libraries that ha

Aside from significant whitespace (which I suppose takes a little getting used to), is there anything that marks out Python's syntax as particularly rigid compared to other languages? I'm struggling to understand what the author i

To broadcast operations (such as addition) between arrays in NumPy, trailing dimensions have to be equal (or be of length 1). In the example given above the 3D array and 2D array have shape (lengths of dimensions): (2, 3, 4) (2,

There are some nice exercises here, good work. For question 48 it might be simpler to just write np.sort(a)[-5:] instead of using argsort() and then using fancy indexing. Better yet, use np.partition(a, kth=-5)[-5:] which scal

No! Never do this in Python. You are making the flattened list by continually concatenating the smaller lists. Each concatenation creates the new bigger list from scratch; the flattened list does not grow dynamically. This is quadratic-perf
