display long lists in member of member of... on one line in python

Question

I have an object with a huge list somewhere down in the bowels. The object's dump (e.g. using print(o)) doesn't fit on one screen.

But if I could manage to have members that are 1-D lists printed comma-separated on one line, the object would be easier to inspect.

How can this be achieved?

EDIT:

Found out that the object I was trying to display had a __repr__ that explicitly showed it's array content in a vertical manner... So this question may be closed.

On regular python lists, arrays are printed on one line.

A snippet to show this.

Answer 2

Most of time this gives a readable output:

import pprint
pprint.pprint(o)

Answer 3

Try doing ", ".join(my_long_list).
