the answer of question 45 is not exactly correct.

[i5cnc]

For example:
z = np.array([1, 2, 3, 4, 5, 5], dtype=int)
z[z.argmax()] = 0
print(z)
will output:
[1 2 3 4 0 5]

But for this question, the correct answer should be:
[1 2 3 4 0 0]

[rougier]

You're right. Do you have a proposal for the correct answer ?

[dfeather]

try this?
z = np.random.randint(1, 5, 10)
print(z)
m = z.max()
z[z == m] = 0
print(z)

[rougier]

Or even simpler (z.max() will be evaluated only once):

z = np.random.randint(1, 5, 10)
z[z ==z.max()] = 0
print(z)

[lealb]

as the answer, can use
Z[Z==Z.argmax()]=0

[ghost]

import numpy as np
x = np.random.random(15)
print("Original array:")
print(x)
x[x.argmax()] = 0
print("Maximum value replaced by 0:")
print(x) # use this
