PydBliteWebpy: The small but functional database access class library used in Python

PydBlite is a small but powerful database access class library, which provides Python developers with a simple and fast database operation method.PydBlite combines the powerful function of the SQLite database and the flexibility of Python, making it easier and efficient to process the database in Python. With PydBlite, you can easily create and manage databases.It provides syntax similar to SQL, allowing you to create tables, insert data, update and delete records.At the same time, PYDBLITE also supports complex query operations, such as conditional filtering, sorting and grouping. Below is a simple example, showing how to use PydBlite to create a table called "Students" and insert some student information: python from pydblite import Base # Create a database table called "Students" db = Base('students.pdl') # Define table field db.create('Name', 'Age', 'Grade') # Insert student information db.insert(Name='Alice', Age=18, Grade=12) db.insert(Name='Bob', Age=17, Grade=11) db.insert(Name='Charlie', Age=16, Grade=10) # save Changes db.commit() In the above code, we first introduced the `pydblite.base` class, which is the main class of pydblite.We created a table called "Students" and defined three fields: name, Age, and Grade.Then we inserted the information of three students using the `Insert` method.Finally, we saved the change by calling the `Commit` method. In addition to creating tables and insert data, PYDBLITE also provides other commonly used database operation methods, such as update records, deletion records and query records.Here are some common operation examples: python # Update the age of the student BOB is 20 db.update(db.Name == 'Bob', Age=20) # Delete students who are younger than 18 years old db.delete(db.Age < 18) # All records in the query table and printed out for student in db: print(student['Name'], student['Age'], student['Grade']) # Filter the query record according to the condition query = db(db.Grade >= 11) for student in query: print(student['Name'], student['Age'], student['Grade']) In the above code, we used the `UPDate` method to update the age of the student" BOB "at 20, and the` Delete` method was used to delete the record of students younger than 18.Then, we used the `For` loop to print out the information of all students.Finally, we used the query method of the `db` object` db () `to filter the query results according to the conditions, and print out the student information of the grade greater than or equal to 11. To use PydBlite, you need to install it in the Python environment.You can use the PIP command for installation: pip install pydblite PYDBLITE is a lightweight library that does not require additional configuration and dependencies.It is very suitable for small items and fast data operation tasks.Whether it is a beginner or an experienced developer, you can easily use PydBlite to process the database operation.
