A= [0, 1, 2] b=a a[0]="spam" print (b[0 ])

Question

I thought the answer should be 0, but under py challenge, the answer is said to be spam.

My thought
A= [0, 1, 2] has been assigned before a[0] was updated to "spam"

Answer 1

First ,list is mutable(means it is changeable)
a=[0,1,2]
b=a
a[0]="spam"
print(b[0])
So, 0 is changed to "spam".
As a result, the answer is "spam".

Answer 2

Web-Learner i know list is mutable, my question is that since b has been updated before a[0] was changed, I thought b will maintain the old version of a except it is explicitly updated again
