Python Tuple

You cannot change a tuple that has been initialized once, but you can assign a new value to the variable that contains the tuple. What this means is

t = ('A', 'B', 'C')

('A', 'B', 'C') cannot be changed in . However, you can assign a new value to t. For example,

t = ('A', 'B', 'C')
t += ('D')

('A', 'B', 'C') cannot be changed like this, but

t = ('A', 'B', 'C')
t = t + ('D',)

In this way, t can be assigned a new tuple called ('A', 'B', 'C', 'D').
