I have looked around for a good way to do this and haven't found one I
am like. It seems that all involve repeating a print for each line. I
would have thought I could find a prebuilt function to do this. Surly
lots of people are printing matrixes and would like nice formating. So
what am I missing?
Look at the pprint module:
arr = [range(10)] * 10
from pprint import pprint
pprint(arr)
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]]
But this doesn't line up the columns, except by accident:
[[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000],
[1, 10, 200],
[300, 4000, 50000]]
