what is a Tuple ?

Tuples are immutable sequences, typically used to store collections of heterogeneous data (such as the 2-tuples produced by the enumerate() built-in). Tuples are also used for cases where an immutable sequence of homogeneous data is needed (such as allowing storage in a set or dict instance).

• according to official docs

In short, tuples are python Data Structure (similar to lists) that is used to store data of any kind, and they cannot be changed once created. They can also be faster than lists.

• Example of a tuple

  ages = (10, 20, 30)
  # create a tuple by using the parenthesis, 
  # lists are using a square bracket
  

to create a tuple of single value always add a comma after the value i.e: age = (10,)

Unpacking a tuple

Let's take the example above and say we want to give each age to three people.

• long solution

ages = (10, 20, 30)

# assigning each value based on the index
john_age = ages[0]
jane_age = ages[1]
sally_age = ages[2]

print(john_age)
print(jane_age)
print(sally_age)

>>> 10
>>> 20
>>> 30

• short solution

ages = (17, 21, 13)

# unpacking the tuple
john_age, jane_age, sally_age = ages

print(john_age)
print(jane_age)
print(sally_age)

>>> 17
>>> 21
>>> 13

See?? you get the same result in just one line. Three variables for the three tuple values
