python 使用两个脚本进行数据库查询

Question

我有两个脚本 main.py 和 testscript.py。在 main.py 上是连接到我的数据库的功能，在 testscript.py 上我将用作我的查询请求并使用 main.py 将此查询调用到我的数据库。添加到 main.py

 if __name__ == '__main__':
        q = "select domain_name from domains_domain limit 10"
        query(q)

并运行脚本

python main.py

按预期工作，但我不知道如何在 testscript.py

上执行此操作

这里是main.py

import MySQLdb
from localdb import *
import socket

host = socket.gethostname()
error_report = "Check if MySQL service is running and user name/password are correct" 

class WeekQuery:
    def __init__(self, name):
        self.name = name

    def query(self):
        cursor = None
        results = None
        week_number = None
        #Connecting to production database
        if host == 'db01':
            try:
                db = MySQLdb.connect("db01", "myuser", "mypass", "mydb")
                cursor = db.cursor()
                cursor.callproc(self)
                results = cursor.fetchall()
                week_number = [i[0] for i in cursor.description]
            except MySQLdb.Error, e:
                try:
                    print "%s \n MySQL Error [%d]: %s" % (error_report, e.args[0], e.args[1])
                except IndexError:
                    print "%s \n MySQL Error: %s " % (error_report, str(e))
        else:

            #local database rename localdb.py_example to localdb.py
            try:
                db = MySQLdb.connect(host=MYSQL_HOST, user=MYSQL_USER, passwd=MYSQL_PASSWD, db=MYSQL_DATABASE)
                cursor = db.cursor()
                cursor.execute(self)
                results = cursor.fetchall()
                week_number = [i[0] for i in cursor.description]
            except MySQLdb.Error, e:
                try:
                    print "%s \n MySQL Error [%d]: %s" % (error_report, e.args[0], e.args[1])
                except IndexError:
                    print "%s \n MySQL Error: %s " % (error_report, str(e))

            #finally:
            #    cursor.close()
            #    db.close()
            print(results, week_number) #For debuging only
        return (results, week_number)

这是我的testscript.py

from main import WeekQuery

def sample():
    q = "select domain_name from domains_domain limit 10"
    x = WeekQuery(q)
    for y in x.query():
        print(y)

您还需要从 main 中导入主机和 error_report。这是你的问题吗？
