What is the output of this code?

Question

import numpy as np
a=np.arange(0,8,2)
b=np.arange(1,8,3)
print(a[2]==b[1])

Answer 1

True

I suggest you to use the playground for such kind of questions.

Answer 2

x = np.arange(2, 8, 2)
x = np.append(x, x.size)
x = np.sort(x)
print(x[1])

Answer = 3

for np.arrange add the first and last number in the array which is 2 + 2, you get 4 add that answer (4) to the last number again you get 6, for x = np.arrange answer is (2,4,6), for np.append(x,x.size) answer is (2,4,6,3) for np.sort(x) answer is (2,3,4,6)... for print(x[1]) answer is 3... remember your indexes python starts from 0

Answer 3

What is the output of this code?

x = np.arange(2, 8, 2)
x = np.append(x, x.size)
x = np.sort(x)
print(x[1])
