Well this at least is a Numeric-specific question, not a general Python one.
Anyways, the string representation can be controlled by supplying the
appropriate callback. From Numeric.py (pardon any unfortunate linewraps):
#Use Konrad's printing function (modified for both str and repr now)
from ArrayPrinter import array2string
def array_repr(a, max_line_width = None, precision = None,
suppress_small = None):
return array2string(a, max_line_width, precision, suppress_small,
', ', 1)
def array_str(a, max_line_width = None, precision = None, suppress_small
= None):
return array2string(a, max_line_width, precision, suppress_small,
' ', 0)
multiarray.set_string_function(array_str, 0)
multiarray.set_string_function(array_repr, 1)
