I have a two dimensional numpy array, and I’m wanting to
change all of the ‘male’ values to 0 and all of the ‘female’
values to 1.

If I try to assign ‘arr2D[row,element]’ to a specific value,
I get an error.

I tried using the code below, but instead of getting my hoped for
array of ‘[[0,0],[1,1]]’ I got an error. ‘IndexError: arrays used
as indices must be an integer…’.

I don’t know how to determine the index of the element that I’m
looking at in my for loop.

import numpy as np

arr2D = np.array([[‘male’,0],[‘female’,1]])

for row in arr2D:
for element in row:
if element == ‘male’:
arr2D[row,element] = 0
if element == ‘female’
arr2D[row,element] = 1

for row in arr2D:
for element in row:
print(element)
