Some interesting things about Tuple in Python

1.

The contents in Tuple cannot be changed. But if there is something changeable in Tuple, it can be changed.

Example:

t = (“a”, “b”, 1, False, [1, 2, 3])

t[4][0] = 6

print(t)   ### (“a”, “b”, 1, False, [6, 2, 3])

2.

If there is only an element in  tuple, like (1), you should plus a “,” after it, like (1, ). Why?

Because in python, (1) will be recognized as the whole number 1 in maths, so be careful.
