The Python language's 3 x is completely non-forward compatible, resulting in a library that we can work with in Python2 X, which is python3 for example MYSQLDB currently MYSQLDB does not support Python3
The 3.x of the Python language is completely non-forward compatible, resulting in a library that we can use normally in python2.x, which is not available to Python3. For example MySQLdb
Currently MYSQLDB does not support python3.x, python3.x connection to MySQL program is: Oursql, Pymysql, MYCONNPY, etc.
Below is the next Python3 how to install and use Pymysql, another two options I will talk about later.
1.pymysql Installation
Pymysql is a substitute for mysqldb in the PYTHON3 environment, enter the command line and use PIP to install Pymysql
2.pymysql use
If you want to use MYSQLDB, then directly at the beginning of the Py file add the following two lines of code.
1234 |
#引入pymysql import pymysql #当成是mysqldb一样使用,当然也可以不写这句,那就按照pymysql的方式 pymysql.install_as_MySQLdb() |
