To use pyhton3.4 to do data analysis, Pip and mysqldb are necessary, a convenient installation of common modules, one for the operation of the database. When the two modules were installed, it took a lot of time to install them because there was no one to guide them.When installing PIP, follow the online tutorial, first download the pip8.1 in the link https://pypi.python.org/pypi/pip, follow the usual method, after extracting the Python setup.py insta

MySQL is a good open source database, it is now widely used, so it is necessary to briefly introduce the method of using Python to operate the MySQL database. The Python operations database requires the installation of a third-party module, which is downloaded and documented in http://mysql-python.sourceforge.net/. Since Python's database module has specialized database module specifications, in fact, no matter what kind of database used in a similar way, here is a demonstration of the code: #

This article describes the python in the mysqldb garbled solution, share to everyone for your reference. Here's how: In general, the most troublesome problem in using MySQL is garbled. To view the code for MySQL: Command: Copy the Code code as follows:Show variables like ' character_set_% '; You can see the following results: Character_set_client is the client-side encoding method;Character_set_connection the encoding used to establish the connecti

This example describes how Python uses MySQLdb to implement exporting an XML file from a database. Share to everyone for your reference. The specific analysis is as follows: Here you need to provide some data to the front end in XML format, which already exists in the current database. If you use Django to return XML data, you need to wrap the head information:Copy the Code code as follows:R = HttpResponse (str_xml) R.mimetype = "Text/xml" r[' conten
