Question

我在同一目录中创建了三个单独的python脚本。脚本一包含一个类，根据我的IP地址给出我的位置（在json fromat中），并将纬度和经度存储在名为 location

的列表中

#geo_location.py

import json
import urllib2

class geo_locate:
    def __init__(self,location_url):
       self.location_url=location_url
       global location
       location=[]

    def locate(self):
       req=urllib2.Request(self.location_url)
       res=urllib2.urlopen(req)
       j=json.loads(res.read())
       location.append(j['latitude'])
       location.append(j['longitude'])
       return location

第二个脚本还包含一个类，该类使用在第一个脚本中获得的纬度和经度从天气网站获取位置键

#get_key.py

import json
import requests
from geo_locate import geo_locate

class get_key():
    def __init__(self,location_key_url,key):
        self.location_key_url=location_key_url
        self.key=key

    def locate_key(self):
        api=[]
        link=self.location_key_url + "=" + str(geo_locate.location[0]) + "," + str(geo_locate.location[1]) + "&apikey=" + self.key
        res=requests.get(link)
        j=json.loads(res.text)
        api.append(j['Key'])
        return api

显示其他两个脚本获取的信息的第三个脚本，即 location和api

#condition.py

from urllib2 import URLError
from geo_locate import geo_locate
from get_key import get_key
url='http://dataservice.accuweather.com/locations/v1/cities/'
api='<api key here>'
send_url='http://freegeoip.net/json'

class main:
    def __init__(self):
        geo_locate(send_url).locate()
        get_key(url,api).locate_key()

if __name__=='__main__':
    try:
        main()
    except URLError,e:
        print e.reason,"\nPlease check connection"

但是当我运行 condition.py 时，我收到错误

Traceback (most recent call last):
File "/home/c0d3d/Documents/accupy/accupy/condition.py", line 18, in <module>
main()
File "/home/c0d3d/Documents/accupy/accupy/condition.py", line 12, in __init__
get_key(url,api).locate_key()
File "/home/c0d3d/Documents/accupy/accupy/get_key.py", line 15, in 
locate_key
link=self.location_key_url + "=" + str(geo_locate.location[0]) + "," + 
str(geo_locate.location[1]) + "&apikey=" + self.key
AttributeError: class geo_locate has no attribute 'location'

如何从 get_key.py 中的 geo_location.py 调用位置？

Answer 1

执行from geo_locate import geo_locate时，只导入类，而不导入整个模块名称空间。 location列表将位于模块根目录。

您应该import geo_locate，之后，当您致电课程时，请执行geo_locate.geo_locate()。

从单独脚本上的另一个python类中的一个python类访问方法变量
