Can someone explain why value of x and y not same?

# Python code a = [1,2,3,4,1] for x in a: print(x) print("\n") for y in a: print(y) a[y] = 0 # output 1 2 3 4 1 1 0 3 0 1

For x you can directly understand that, there it iterates over list and prints element now for y you are replacing element after printing. First a[1] = 0(as y is 1 for the first iteration) this changes index one element to 0 so you can understand for every element

You tagged three languages: python, c++, java. Only one is relevant.

The reason why the output is different is that you change a inside the second loop.

Got the answer. Changing the list inside loop and iterating over same list. Due to which list next index data of the iterating list is getting modified.
