How to pretty-print a numpy.array without scientific notation and with given precision?
...
If `x` and `A` are numbers, this is like `"format" % (x, A, "str", B)` in python.
If they're numpy arrays, each element is printed in its own format:
`x`: e.g. [ 1.23 1.23e-6 ... ] 3 digits
`A`: [ [ 1 digit after the decimal point ... ] ... ]
with the current `np.set_printoptions()`. For e...

Difference between numpy.array shape (R, 1) and (R,)
...ay to think of this is that numpy is working exactly as expected here, but Python's printing of tuples can be misleading. In the (R, ) case, the shape of the ndarray is a tuple with a single elements, so is printed by Python with a trailing comma. Without the extra comma, it would be ambiguous with ...
