(1) variable = a if exper else B(2) variable = (exper and [B] or [c]) [0](2) variable = exper and B or c The above three methods can achieve the goal, similar to the C language variable = exper? B: c; that is, if the value of the exper expression is

I wrote the test code for the fork process under Python (to illustrate this problem is not necessarily appropriate ): Def fork (a): def now (): import datetime return datetime. datetime. now (). strftime ("% S. % f ") import OS import time print now

Python is an interpreted, object-oriented, and dynamic data-type high-level programming language. This document describes an example of Python class inheritance. The instance code is as follows: #! /usr/bin/python # Filename: inherit.py # Author:

This section describes how to use Python on the Linux platform. 1. Install Python. Currently, most releases come with Python, so you do not need to install Python. If you want to install it, you can use the corresponding system installation command.

1. Create a ing Instance) We have introduced how to map database entity tables to Python classes. Now we can create an Instance for this class. We are still using the User class in the previous article as an example, let's create a User object:Copy

I analyzed the time format features such as 19920203, 199203, 1992.02.03, 1992.02, 1992-02-03, 1992-02, and 920203. The regular expressions are listed as follows:Copy codeThe Code is as follows:^ ((? : 19 | 20 )? \ D {2}) [-.]? ((? : [0-1]? | 1) [0-9

1. Testing and improving procedures In the fifth lecture, it has been implemented to solve the square root using the bipartite method. The Code is as follows: def squareRootBi1(x,epsilon): assert epsilon > 0,'epsilon must be postive,not' +

Consider the following python program:Copy codeThe Code is as follows:#! /Usr/bin/env pythonImport sysSys. stdout. write ("stdout1 ")Sys. stderr. write ("stderr1 ")Sys. stdout. write ("stdout2 ")Sys. stderr. write ("stderr2 ")The sys. stdout. write

Python contains six built-in sequences: This article mainly discusses the two most common types: List and tuples. The main difference between a list and a group is that a list can be modified, but a list cannot be modified. In general, the list can

The following error is reported when an image processing program is created on the server running the Python environment today: NameError: global name 'Image' is not defined After importing the Image, it is found that Python does not have its own

AVL is a binary search tree with a balance condition. Generally, the height difference between the left and right subtree of each node is 1 (the height of the empty tree is defined as-1 ). In an AVL tree with a height of h, the minimum number of

A simple version of logging. config is implemented, which generally supports configuration through the config file.Another better way is to use the logging. config. fileConfig (log_config_file) method to read in and modify the handler method. Copy

Although Python's object-oriented programming principles are similar to those of other languages, it still has its own programming process and code structure, which is easy to remember. The following describes how to calculate the Circle area and

Python comes with a module for processing python. You can directly import json when using it. You can use the loads method to convert a json string to a python object. The corresponding relationship is as follows:JSON PythonObject dictArray

The urllib2.urlopen () function does not support authentication, cookie, or other advanced HTTP functions. To support these functions, you must use the build_opener () function to create a custom Opener object. Copy codeThe Code is as
