How do I print an aligned numpy array with (text) row and column labels?

Question

Is there any elegant way to exploit the correct spacing feature of print numpy.array to get a 2D array, with proper labels, that aligns properly? For example, g

Answer 1

You can use IPython notebook + Pandas for that. Type your original example in IPython notebook:

import numpy
x = numpy.array([[85, 86, 87, 88, 89], 
                 [90, 191, 192, 93, 94], 
                 [95, 96, 97, 98, 99], 
                 [100,101,102,103,104]])

row_labels = ['Z', 'Y', 'X', 'W']
column_labels = ['A', 'B', 'C', 'D', 'E']

Then create a DataFrame:

import pandas
df = pandas.DataFrame(x, columns=column_labels, index=row_labels)

And then view it:
