Python Tuples

Links: Journey to Data Scientist

Characteristics

• Ordered
• Can contain arbitrary objects
• Accesible via index
• Can be nested
• Immutable

It shares most of the characteristics as Lists except it is immutable.
Therefore, operations on Tuples are faster than Lists (when number of elements is getting larger)

Immutable

t = ("apple","moon","3",57,9.99,0x3e)
print(t)
print(t[1])
print(t[3:6])
print(t[::4])

Output:
('apple', 'moon', '3', 57, 9.99, 62)
moon
(57, 9.99, 62)
('apple', 9.99)

If we try to modify the value:
t[0] = "orange"
Output:
--------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-9-9456d7af7fd3> in <module>
----> 1 t[0] = "orange"

TypeError: 'tuple' object does not support item assignment

Unpacking Tuples

t = ("apple","moon","3",57,9.99,0x3e)
(u1,u2,u3,u4,u5,u6) = t
print(u1,u2,u3,u4,u5,u6)

Output: apple moon 3 57 9.99 62
