使用请求模块时，无法建立新连接：[Errno 11001] getaddrinfo失败'））

Question

最初尝试使用一个URL并符合request.get（url）的方法。但是现在我要检查URL列表。

所以我做了一个For循环，每次都调用请求。但这还没有遵守，也不了解问题出在哪里。我在列表http://microsoft.com和http://google.com中使用了两个URL。我通过给https尝试过，但是收到了相同的错误。

import requests
def main():
    f=open("list.txt","r")
    print(f)
    f1= f.readlines()
    for x in f1:
        print (x)
        r= requests.get(x)
        print(r.status_code)


if __name__ == "__main__":
   main()

以下是编译程序时收到的错误

<_io.TextIOWrapper name='list.txt' mode='r' encoding='cp1252'>
http://microsoft.com
