List vs Tuple vs Dictionary vs Set.py

# List [] vs Tuple () vs Dictionary vs Set{}

# List [] – add, remove, and change data             ['apple', 'banana', 'cherry']
# Tuple () – once created, cannot change in size or content i.e. immutable  i.e. coordinate(x,y,z)      ('apple', 'banana', 'cherry')
# Set {}  - is unordered and has no duplicate values             {'apple', 'banana', 'cherry'}
# Dictionary{:} keys, not ordered data(aka array,map) {'name':'apple, 'color':'green'}
