Command line run Python script In this section, we'll write a few simple database management scripts. Before that, let's review how to execute a Python script from the command line. If Linux or OS X's operating system requires permission to execute scripts. For example: chmod a+x script.py The script has a command line that points to using an int

sqlite3import OS ''' SQLite database is a very small embedded open source database software, that is to say, there is no independent maintenance process, and all maintenance comes from the program itself. In python, sqlite3 is used to create a database connection. When the specified database file does not exist, the connection object will automatically create a

Python Connection database learning DB-API details, pythondb-api Preface Everyone knows that if you want to connect to a database in Python, whether it is MySQL, SQL Server, PostgreSQL, or SQLite, the cursor method is used, so you have to learn Python DB-API. All of Python's database interface programs comply with the

command-line mode to run a Python script In this section, we will write some simple database management scripts. Let's review how to execute the Python script from the command line.

specifications to a certain extent. DB-API defines a series of required objects and database access methods to provide consistent access interfaces for various underlying database systems and a variety of database interface programs. Since DB-API provides consistent access interfaces for different databases, porting code between different databases is easy. Python database connection process: Hierarchy of

=connection.cursor() If no error message is displayed, your database configuration is correct. Otherwise, you must check the error information to correct the error. The above code is an example of the code before connecting Python to the mysql database.
