Question

我在全局脚本中将policydict定义为policydict = {}，当我从主脚本运行更新策略时，得到的回溯policydict未定义。

import mysql.connector
import datetime
import xlrd
import re
import os
import csv

from Global import guardpointdict


def updatepolicies():
    global policydict

#read in csv from vormetric
    with open('policies.csv') as polcsvfile:
        policies = csv.DictReader(polcsvfile)
        for row in policies:
        #print(row['Report Id'], row['Status Id'], row['Host Name'], row["OS Type"], row['Host Description'], row['License Type'],
              #row['One-Way Enabled'], row['FS Agent Registration Status'], row['FS Agent Version'], row['Host Name'], row['Last Policy Update'],
              #row['Guard Point Id'], row['Guard Path'], row['Policy Id'], row['Policy Name'], row['Guard Enabled'],
              #row['Guard Point Status'], row['Error Reason'])



        #create database connection

            conn = mysql.connector.connect(host='xxx', user='xxx', 
            password='xxx', db='mydb')
            cursor = conn.cursor()


        #Create parameters for stored procedure
            policyparams = (row['Policy Name'], row['Policy Description'], 0)

        #call stored procedure
            returnvalue = cursor.callproc('update_policies', policyparams)

        # create dictionary used for keypair in guardpoints table
             policydict[row['Policy Name']] = returnvalue[2]



            conn.commit()
            conn.close()

回溯（最近通话最近）：文件“ C：/Users/n0256468/PycharmProjects/scorecard/Main.py”，第16行，在 updatepolicies（）文件“ C：\ Users \ n0256468 \ PycharmProjects \ scorecard \ policies.py”，第38行，位于updatepolicies中 policydict [row ['政策名称']] =返回值[2] NameError：名称“ policydict”未定义

以退出代码1完成的过程

似乎您在另一个文件中定义了policydict，但是您并未在代码中的任何地方使用from module import policydict。如果仅导入模块，则必须在变量前加上模块名称。例如，如果policydict在mymodule中：

import mymodule

print(mymodule.policydict)

如果不想使用模块名称作为前缀，则可以执行以下操作：

from mymodule import policydict

print(policydict)

写入global policydict是指当前文件中的全局变量policydict 。

如何修复NameError：未定义名称'policydict'
