NumPy: Pretty print tabular data

Question

I would like to print NumPy tabular array data, so that it looks nice. R and database consoles seem to demonstrate good abilities to do this. However, NumPy\'s built-in prin

Answer 1

I seem to be having good output with prettytable:

from prettytable import PrettyTable
x = PrettyTable(dat.dtype.names)
for row in dat:
    x.add_row(row)
# Change some column alignments; default was 'c'
x.align['column_one'] = 'r'
x.align['col_two'] = 'r'
x.align['column_3'] = 'l'

And the output is not bad. There is even a border switch, among a few other options:

>>> print(x)
+------------+---------+-------------+
| column_one | col_two |   column_3  |
+------------+---------+-------------+
|          0 |  0.0001 | ABCD        |
|          1 |  1e-005 | ABCD        |
|          2 |  1e-006 | long string |
|          3 |  1e-007 | ABCD        |
+------------+---------+-------------+
>>> print(x.get_string(border=False))
 column_one  col_two    column_3  
          0   0.0001  ABCD        
          1   1e-005  ABCD        
          2   1e-006  long string 
          3   1e-007  ABCD
