Show an array in format of scientific notation

Question

I would like to show my results in scientific notation (e.g., 1.2e3). My data is in array format. Is there a function like tolist() that can convert the array to fl

Answer 1

You can format each of the elements of an array in scientific notation and then display them as you'd like. Lists cannot be converted to floats, they have floats inside them potentially.

import numpy as np
a = np.zeroes(shape=(5, 5), dtype=float)
for e in a.flat:
    print "%E" % e

or

print ["%E" % e for e in a.flat]
