2.1 Some concepts and codes
    The most basic data structure in Python is the sequence. Python built-in sequence, list, Ganso, String. The data type of the dictionary is mapping (the data type of the only built-in mappings in Python). Sequences and mappings are two main types of containers. Python does not have a separate heap (data structure) type. There is only one module (HEAPQ) that contains some heap operation functions.
    
    The environment variable is not part of the Python interpreter, it belongs to the operating system.
If you do not set the __all__,import* statement, the default import module has all the global names that do not begin with the underscore .

Map () function and lambda (omit some unnecessary for loop code, the following can be used as a list deduction ...) ）
