Data Analysis using Python - Broadcasting and Vectorized Operation

The question given is fine, but i guess the answer to that is wrong. Please check and let me know, Coz the answer should be
[20,21,22,23,24]
but it says
[0,1,2,3,4] is the right anser.

what’s the question you are talking about?

What is the value of a after you run the following code?

a = np.arange(5)
a + 20

The answer should be
[20,21,22,23,24] , right?

but it says [0,1,2,3,4] is the right answer

add print(a) below and execute it

The answer [0,1,2,3,4] is correct, because doing a + 20 will return the array [20, 21, 22, 23, 24] but won’t assign it to a (that’s the tricky part of the question). The + operation by itself is immutable. In order to assign the result to a, you’d have to use the += operator.
