Creating 2D Array - jpinko - Nov-23-2020 Hi All, My code is the following: import numpy import math a = numpy.arange(1, 11) b = numpy.arange(0, .02, .001) v = [] for c in a: v.append([]) for d in b: numpy.append(v[c],(1 / c ** 2) * math.exp( -c ** 2 * math.pi ** 2 * d))I'm looking to create an a x b array composed of the following: How would I do this? As is my code is producing TypeError: list indices must be integers or slices, not numpy.float64.Thanks, Jonathan RE: Creating 2D Array - jefsummers - Nov-23-2020 I'd use a Pandas dataframe |
