Python implements objects that support JSON storage and parsing, and pythonjson
We know that the JSON module can be used to conveniently store basic Python data (such as dict and list) as files permanently, at the same time, you can use custom conversion functions and methods that inherit JSON encode decode to store custom classes. This article is based on the p
. how does python handle this? The answer is that it does not need to be processed at all, because python can accept any type of parameters. if the functions are the same, different parameter types may be the same code in python, there is no need to create two different functions.
In case 2, functions are the same, but the number of parameters is different. how
Old text backup: Python international support,
Python supports internationalization (i18n) through the gettext module, and supports the multi-language interface of the program. below is my multi-language support implementation:

We know that the JSON module makes it easy to store data for Python primitives (dict, lists, and so on) permanently into files, as well as to implement custom class storage through custom conversion functions and inherited JSON encodedecode methods. This article is based on the previous "Python JSON module", the implementation of Python
If you want to add plugins such as Youcompleteme to Vim, then you need vim with Python support, which is specified in the first compilation option. Here's how:1. See if Python is supportedgrep pythonDescription does not join Python support, this time if you use youcompleteme
Ubuntu 17.10 installs the "Love Wallpaper" of the Deb package when the Python-support dependency is missing. Using sudo apt-get-f install is not fixed. The official source was checked, and the result Python-support was discarded.But "Love wallpaper" still want to use drops, Pytho
This article mainly introduces how to use the gettext module in Python3 to translate the Python source code to support multiple languages. The Python source code translation serves as an example to demonstrate the functions and usage of gettext, you can refer to a Python 3 program and want it to work in other languages
;Ok! So far all the preparatory work has been doneAdd:Note: The above steps can also be done with poedit This software, the official website has a detailed use of the tutorialIn addition, once the string to be translated in Python code changes (modified, added or deleted), you can use the msgmerge command instead of the msginit command when you need to regenerate the Po file, for example:Msgmerge-u Zh_cn.po My_app.pot
3. Add internationalizatio
Use the gettext module in Python3 to translate Python source code to support multiple languages.
You have written a Python 3 program and want it to work in other languages. You can copy all the code libraries, and then deliberately check each. py file to replace all the text strings found. But this means that you have two independent copies of your code. Every ti
Incrementaldecoder, but it's highly recommended to use StreamReader and StreamWriter, because using them will greatly simplify your code. For example, there is a Test.txt file, which is encoded as GBK, and now I need to convert its encoding to UTF8, you can write the following code:[Python]View Plaincopy
#coding: UTF8 2
Import Codecs
# Open File If you open the file with the Codecs.open () method here, you do not have to create reader a
Note: This chapter is relatively simple to introduce, but examples are used, mainly to master if connected, using the database, and to do the example of SQLite------Python database APITo solve the compatibility problem between various database modules in Python, a standard DB API has now been passed. The current API version (2.0) is defined in the Python Database
different. How does python handle this? As you know, the answer is the default parameter. You can solve the problem by setting the missing parameters to the default parameters. Because you assume that the functions are the same, the missing parameters are all needed.
Well, given that both scenario 1 and scenario 2 have solutions, python naturally does not need function overloading. I add that Python3 can
problems.1. The variable parameter type.2. The number of variable parameters.In addition, a basic design principle is that only if the function of the two functions is identical except for the parameter type and the number of parameters, then the function overload is used, if the function of two functions is different, then the overload should not be used, but a function with different names should be used.Okay, so for scenario 1, the functions are the same, but the parameter types are differen
This article mainly introduces the support of the Python Tornado framework for subdomain names and wildcard domain names. Tornado, as a typical asynchronous framework, is very popular among Python developers, for more information, see Tornado's support for subdomain names and wildcard Domain Names (except in particular
