Python 迭代对象属性
我该如何在Python中遍历一个对象的属性呢?
我有一个类:
class Twitt:
def __init__(self):
self.usernames = []
self.names = []
self.tweet = []
self.imageurl = []
def twitter_lookup(self, coordinents, radius):
cheese = []
twitter = Twitter(auth=auth)
coordinents = coordinents + "," + radius
print coordinents
query = twitter.search.tweets(q="", geocode=coordinents, rpp=10)
for result in query["statuses"]:
self.usernames.append(result["user"]["screen_name"])
self.names.append(result['user']["name"])
self.tweet.append(h.unescape(result["text"]))
self.imageurl.append(result['user']["profile_image_url_https"])
现在我可以通过这样来获取我的信息:
k = Twitt()
k.twitter_lookup("51.5033630,-0.1276250", "1mi")
print k.names
我想要做的是像这样在一个循环中遍历这些属性:
for item in k:
print item.names

在Python中遍历对象的属性:
class C:
a = 5
b = [1,2,3]
def foobar():
b = "hi"
for attr, value in C.__dict__.iteritems():
print "Attribute: " + str(attr or "")
print "Value: " + str(value or "")
输出结果:
python test.py
Attribute: a
Value: 5
Attribute: foobar
Value: <function foobar at 0x7fe74f8bfc08>
Attribute: __module__
Value: __main__
Attribute: b
Value: [1, 2, 3]
Attribute: __doc__
Value:

你可以使用Python的一个常用方法,叫做 vars()
:
for attr, value in vars(k).items():
print(attr, '=', value)

更新:
在Python 3中,你应该使用 items()
而不是 iteritems()
Python 2
for attr, value in k.__dict__.iteritems():
print attr, value
Python 3
for attr, value in k.__dict__.items():
print(attr, value)
这段代码会打印:
'names', [a list with names]
'tweet', [a list with tweet]
