This should do what you want:

array_copy = my_array.copy()
array_copy[array_copy == 2] = 0

Dear sirs,


Please allow me to ask you a beginner's question.

I have an nparray whose shape is (144, 91, 1). The elements of this array
are integer "0", "1" or "2", but I don't know which of the three integers
is assigned to each element.
I would like to make a copy of this array, and then replace only the
elements whose value is "2" into "0". Could you teach how to make such a
modification?


Sincerely yours,

Tetsuro Kikuchi
