One, Collections moduleOn the basis of the built-in data types (dict, list, set, tuple), the collections module also provides several additional data types: Counter, deque, Defaultdict, Namedtuple, and Ordereddict.1.namedtuple: Generate a tuple that can access the content of an element by using a name2.deque: Double-ended queue to quickly append and eject objects from the other side3.Counter: Counter, mainly used to count4.OrderedDict: Ordered Diction

The most important feature of the class is that once the instantiation cannot modify the value of the property" "5. Deque: Double-ended queue　　　When using the list to store data, accessing the elements by index is fast, but inserting and deleting elements is slow because list is linear and the data is l

Python Program Architecture:a program is a module of the system, it has a top-level script file (can run the program after startup) and multiple module files, scripts and modules are text files containing Python statements, and Python's standard library provides a series of pre-written modulesPython

subprocess module of Python important moduleWe often use Python to execute system commands or scripts, and the system's shell commands are independent of your Python process, and each execution of a command is equivalent to initiating a new process that invokes a system command or script

ModuleModule is a very simple Python file, a single python file is a module, two files is two modules.What is the function of the Python module?1, the module has many function methods, using these methods can be more simple to do

The random module in Python is used to generate random numbers. Here are some of the most commonly used functions in the random module.Random Random.random () is used to generate a 0 to 1 number of random character points: 0 >>> print random.random () 0.283212844881 Uniform Random.uniform is used to generate a number of random characters within a specified range, one of two parameters is the upper bound

The Python OS module contains common operating system features. This module is especially important if you want your program to be platform-agnostic. (in one language) two, common Method 1, os.name output string indicates the platform being used. If the window is ' NT ', it is ' POSIX ' for Linux/unix users. 2. The OS.GETCWD () function gets the current working d

What does serialization mean?is to store the data in memory on the hard disk.Why do I have to put the data in memory on the hard disk?1. The program is running, shutting down, memory data loss.2. The next time the program starts again, read back from the hard disk, or the original format, it is very good.3. Most of the data in memory is in the form of nested dictionaries.What is the point of extracting the memory data?1. Share the memory data with other people through the network.2. You can shar
