print(f'x is not equal to z = {flag}') # python is strongly typed language s = '10' print(f'x is not equal to s = {x!=s}') Output: When we use not equal operator, it calls__ne__(self, other)function. So we can define our custom implementation for an object and alter ...

The loop iterates over iterable while the conditional statement checks if the target value is equal to the current value. Note that the condition checks for object identity with is or for value equality with the equality operator (==). These are slightly different but complementary tests....
