无法通过python中的对象数组解包不可iterable对象/iteraing

python

我想遍历一个URL对象数组中的所有对象

class Url(object):
    pass

a = Url()
a.url = 'http://www.heroku.com'
a.result = 0
b = Url()
b.url = 'http://www.google.com'
b.result = 0
c = Url()
c.url = 'http://www.wordpress.com'
c.result = 0

urls = [a, b, c]

for i, u in urls:
    print(i)
    print(u)

但是,当我运行此脚本时,它会返回以下错误:

TypeError: cannot unpack non-iterable Url object

我该怎么解决这个问题?

试试这个:

class Url(object):
    pass

a = Url()
a.url = 'http://www.heroku.com'
a.result = 0
b = Url()
b.url = 'http://www.google.com'
b.result = 0
c = Url()
c.url = 'http://www.wordpress.com'
c.result = 0

urls = [a, b, c]

for i in urls:
    print(i)

遍历URL。要获取结果和URL(我认为您正在尝试这样做),请执行以下操作:

class Url(object):
    pass

a = Url()
a.url = 'http://www.heroku.com'
a.result = 0
b = Url()
b.url = 'http://www.google.com'
b.result = 0
c = Url()
c.url = 'http://www.wordpress.com'
c.result = 0

urls = [a, b, c]

for c,i in enumerate(urls):
    print("index is ",c)
    print(i.result)
    print(i.url)
