how to add or append an element to a tuple?

Answer 1

# try this way
>>> a = (1,2,3)
>>> a
(1,2,3)

>>> a = a.__add__((4,))
>>> a
(1,2,3,4)

# don't forget the comma after the 4

Answer 2

Can be done by unpacking a tuple and repacking it.

My_tup = (1,2,3)

x, y, z = My_tup #unpacks to x y and z
x += 3
My_tup = (x, y, z) #repacks tuple with new val

This works with small tuples, but is not efficient for larger ones.
