role name = "test" # define a variable: the change in the state is used to process
# query "test" memory space ID (name)
# string variable digital dictionary or list of tuples immutable
# immutable: when the variable name when the names were again reassigned memory address: For example: a string of digital tuple (itself can not be modified, etc.)
# variable: when you modify the contents of the address space which does not change: For example: lists, dictionaries (key corresponding to the value, is modified value)
string:
List
Access sequence:
1. sequential access: access 0.1.23 like sequence is: string tuples
2. Map of access: Dictionaries
3. Speed: faster than a dictionary list, but dictionaries comparison of total memory
4. The direct access number to access
Store holds the number of elements:
Type containers: a plurality of values can be stored: for example: a list of tuples dictionaries
Atoms: number string
