# Python Standard Data Structures
# List Set Tuple Dictionary(Dict)

# Syntax
## List []
## Set  {}
## Tuple ()
## Dict {key:value}

# Values
## List single values
## Set single values
## Tuples READ ONLY single values
## Dict Key READ ONLY Value READ/WRITE   key: value

# Duplicates Allowed
## List Yes ["Bob","Joe","Bob"] > len(3) Bob,Joe,Bob<Robert>
## Set No Last In {"Bob","Joe","Bob"}  > len(2) Bob,Joe<Joeseph>
## Tuple Yes ("Bob","Joe","Bob") > len(3) Bob,Joe,Bob READ ONLY
## Dict Key No duplicates Value Yes duplicates
## { "fname": "Joe", "lname": "Joe" }
