PydbliteWebpy: Lightweight database library used in Python Web development
PydBliteWebpy is a lightweight database library for use in Python Web development.It is based on Python's built -in library SQLite3 and provides a simple, fast and easy -to -use database operation interface.
SQLite is an embedded database engine that does not require a separate server process and allows direct reading and writing database files.The goal of PydBliteWebpy is to use the advantages of SQLite to provide a simple but powerful database solution for Python Web developers.
It is very simple to use PydbliteWebpy for database operations.The following is an example code that shows how to create a database, create a data table, insert data, query data, and update data.
First, we need to install the PydBliteWebpy library.You can use the following command to install it through PIP:
pip install PyDBLiteWebPy
Next, we need to import library and connect to the database:
python
from PyDBLiteWebPy import PyDBLiteWebPy
db = PyDBLiteWebPy('mydatabase.db')
Then we can create a data table:
python
db.create_table('students', name=str, age=int)
Next, we can insert some data:
python
db.insert ('Students', {'name': 'Zhang San', 'Age': 20})
db.insert ('Students', {'name': 'Li Si', 'Age': 22})
We can also check the data:
python
results = db.select('students', where={'age': 20})
for row in results:
print(row['name'], row['age'])
Finally, we can update the data:
python
db.update('students', where={'name': '张三'}, data={'age': 21})
The above is a simple example, showing how to use PydBliteWebpy for database operations in Python Web development.You can further explore the function and usage of the library according to your needs.
In order to allow this library to play, you also need to set the web framework (such as web.py) and configure the database connection information.These configurations will include database file paths, user names, passwords, etc.You can refer to the official documentation of the framework to understand how to configure and use PydBliteWebpy correctly.
