python - How to display a 2D list in this form? -


how can convert 2d list this?

lista=[[1, 2, 3],[3, 4, 5],[8, 5, 9]]   listb=[[1 2 3]        [3 4 5]        [8 5 9]]

as pointed out, have same representation of 1 list in python, list list conversion doesn't make sense. however, if want list string conversion - ways output list nice string, have option of pprint, or pretty-printing. module standard library seems pretty close you're looking for:

import pprint  l = [[1, 2, 3],[3, 4, 5],[8, 5, 9]]  pprint.pprint(l, width=12)

gives output

[[1, 2, 3],  [3, 4, 5],  [8, 5, 9]]

now i've had artificially reduce maximum width bit lists short pprint, default, not consider them worth shortening.

also, if want string representation in program, can use pprint.pformat in pretty same way, except returns string:

import pprint  l = [[1, 2, 3],[3, 4, 5],[8, 5, 9]]  s = pprint.pformat(l, width=12)
