BetaThis is because now C is a 1D array (C.ndim == 1), and so when iterating over C, each integer element is pulled out and assigned to c. Now in Python, integers are immutable, meaning that in-place updates are not allowed, effectively transforming c += 1 into c = c + 1, where c now refers to a new integer, not coupled to C in any way.

BetaOkay, let us see what the above code does! we assigned the string “apple” to the variable str1 and the string “banana” to the string str2.; In line 3 above we are checking if variables str1 and str2 are equal and as expected the python interpreter prints out False.; In line 5 we have reassigned the variable str2 to “apple” and we are doing the same equality check once more.
