类型错误:无法连接“str"和“instance"对象(python urllib) [英] TypeError: cannot concatenate 'str' and 'instance' objects (python urllib)

问题描述

编写一个python程序，在使用urllib.urlopen函数时出现了这个错误.

Writing a python program, and I came up with this error while using the urllib.urlopen function.

Traceback (most recent call last):
File "ChurchScraper.py", line 58, in <module>
html = GetAllChurchPages()
File "ChurchScraper.py", line 48, in GetAllChurchPages
CPs = CPs + urllib.urlopen(url)
TypeError: cannot concatenate 'str' and 'instance' objects


 url = 'http://website.com/index.php?cID=' + str(cID)
        CPs = CPs + urllib.urlopen(url)

推荐答案

urlopen(url) 返回一个类似文件的对象.要获取字符串内容，请尝试

urlopen(url) returns a file-like object. To obtain the string contents, try

CPs = CPs + urllib.urlopen(url).read()
