Usually in the for loop, if we say

for i in a: #a=[1,2,3]
print(i)

We get the output as 1,2,3 because each element of list "a" is assigned to "i" in each iteration.

In the example you have taken each element of list "a" gets assigned to "a[1]" and finally you get the output as 1,8,2,3,5,6,8 because the last element which is assigned to a[1] is 8 which is the last element of the list which is specified.

It can better be understood if you keep the "print(a)" in the loop rather than outside of it. See the below code...

This was cool question. I myself took time to understand...😅😅

Answer 4

Soo in for i in a: ( here i represent the index) and in for a[1] in a:(what is a[1]).i think it means the index in the list to be replaced.
