Python: how to enclose a tuple in a tuple • Programmer

Tuples in python can be nested.

If simply add one tuple to another through the concatenation operation “+”, python will merge the values of the tuples:

a = ((1, 2), (3, 4))
print(a)    # ((1, 2), (3, 4))

b = (5, 6)
print(b)    # (5, 6)

a += b
print(a)    # ((1, 2), (3, 4), 5, 6)

a = ((1, 2), (3, 4))

print(a) # ((1, 2), (3, 4))

b = (5, 6)

print(b) # (5, 6)

a += b

print(a) # ((1, 2), (3, 4), 5, 6)

In order an added tuple to become nested, put a comma “,” after an added tuple:

a += b,
print(a)    # ((1, 2), (3, 4), (5, 6))

1 2	a += b, print(a) # ((1, 2), (3, 4), (5, 6))
