How to replace a value in array in numpy python

Question

I have a very basic question in numpy arrays:

My array looks something like this:

Array = [["id1", "1.0"],["id2", "0.0"]]

I want to read the second element of the array and replace with an another character. Its like

for i in range(0,len(array)):

    if array[i] == "0.0":

        array[i] = "ClassA"

    else

        array[i] = "ClassB"

How to achieve this. I am not able to read "0.0" or "1.0" correctly.
Please help.

You have two arrays inside an array. The below code should work:

array = [["id1", "1.0"],["id2", "0.0"]]

for i in range(0,len(array)):
    if array[i][1] == "0.0":
        array[i][1] = "ClassA"
    else:
        array[i][1] = "ClassB"
