Python API 2.0Starting with 2.0 things is more complicated, but you get more discrete and readable classes:#!/usr/bin/env pythonImport JSONFrom collections Import NamedtupleFrom Ansible.parsing.dataloader Import DataloaderFrom Ansible.vars import VariablemanagerFrom Ansible.inventory Import InventoryFrom Ansible.playbook.play Import playFrom Ansible.executor.task_queue_manager import TaskqueuemanagerFrom An
position of the pointer after the move, to the location of the next data
print Cur.fetchone ()
print Cur.fetchone ()
# indicates the country gets a few from the current position of the pointer
print Cur.fetmany (2)
# Scroll similar to the previous seek, you can specify that
the location of the # position is located in one of two ways: relative position and absolute position
# There's no egg in it, It's better to read directly from the database.

It is well known that a service (Wsgi interface) written in scripting languages requires a server container, common such as PHP php-fpm, LIGHTD, and so on. The uwsgi,uwsgi used in Python is a new protocol based on WSGI that can be used to deploy script programs such as Python. However, there may be some unexpected problems with developing a code architecture that is unfamiliar to UWSGI and the
