How do you append to a tuple from a loop in Python?
Append to a Python Tuple Using Tuple Concatenation While Python tuples don’t offer a dedicated method to append values, we can emulate appending to a tuple by using tuple concatenation. In fact, when we do this, we actually create a new tuple, even if we apply it to the same variable as before.
