Using Python to Operate Perst

To use Python to operate the Perl database, you need to install the pyperl library. You can install the pyperst library through the pip command: pip install pyperst The following is a complete Python code example that shows how to connect to a Perl database and perform data insertion, query, modification, and deletion operations: python from pyperst import Database, Field #Creating Database Objects db = Database("mydb") #Define Data Model class Person(db.Model): name = Field(str) age = Field(int) #Establishing a database connection db.connect() #Create a data record person = Person(name="John", age=25) #Insert Data Record person.save() #Query data all_people = Person.select() for person in all_people: print(person.name, person.age) #Modify data person.name = "John Smith" person.save() #Delete data person.delete() #Close database connection db.close() In this code sample, we first create a database object and then define a data model called 'Person', which has two fields called 'name' and 'age'. Next, we establish a database connection using the 'connect()' method. Then a 'Person' object was created and inserted into the database using the 'save()' method. Afterwards, we use the 'select()' method to query all 'Person' records in the database and print each person's name and age. Then we modified a person's name and used the 'save()' method to save the changes. Finally, we deleted this person's record using the 'delete()' method. Finally, we use the 'close()' method to close the database connection.
