How to pretty-print a numpy.array without scientific notation and with given precision?

Question

I\'m curious, whether there is any way to print formatted numpy.arrays, e.g., in a way similar to this:

x = 1.23456
print \'%.3f\' % x

FYI Numpy 1.15 (release date pending) will include a context manager for setting print options locally. This means that the following will work the same as the corresponding example in the accepted answer (by unutbu and Neil G) without having to write your own context manager. E.g., using their example:

x = np.random.random(10)
with np.printoptions(precision=3, suppress=True):
    print(x)
    # [ 0.073  0.461  0.689  0.754  0.624  0.901  0.049  0.582  0.557  0.348]
