Tuples in Python

• A tuple is an immutable sequence type.

• The first and the clearest distinction between lists and tuples is the syntax used to create them - tuples prefer to use parenthesis, whereas lists like to see brackets

• Although it's also possible to create a tuple just from a set of values separated by commas.

    tuple_1 = (1, 2, 4, 8)
    tuple_2 = 1., .5, .25, .125
  

• If you want to get the elements of a tuple in order to read them over, you can use the same conventions to which you're accustomed while using lists.

    my_tuple = (1, 10, 100, 1000)
  
    print(my_tuple[0])
    print(my_tuple[-1])
    print(my_tuple[1:])
    print(my_tuple[:-2])
  
    for elem in my_tuple:
        print(elem)
  

• What else can tuples do for you?

  • the len() function accepts tuples, and returns the number of elements contained inside;
  • the + operator can join tuples together (we've shown you this already)
  • the * operator can multiply tuples, just like lists;
  • the in and not in operators work in the same way as in lists.
