# Tuples are used to store multiple items in a single variable
# Tuple items are ordered, unchangeable, and allow duplicate values.


# List is a collection which is ordered and changeable. Allows duplicate members.
# Tuple is a collection which is ordered and unchangeable. Allows duplicate members.
# Set is a collection which is unordered, unchangeable*, and unindexed. No duplicate members.
# Dictionary is a collection which is ordered** and changeable. No duplicate members.

# Method 	Description
# count()	Returns the number of times a specified value occurs in a tuple
# index()	Searches the tuple for a specified value and returns the position of where it was found
