Python throws a TypeError if youll try to update the tuple. The resulting slice includes all elements from the start index up to (but not including) the end index: You can also use negative indices to slice from the end of the tuple: Advice: If you want to learn more about slicing in Python, you should definitely take a look at our article "Python: Slice Notation on List". The comparison is performed element-wise, and the result is a Boolean value indicating whether or not the comparison is true: You can unpack a tuple into multiple variables using the assignment operator (=).
