Python API回复 - 如何格式化/选择回复布局

Question

我对Python（我认为是2.7）已经有了2天的了解，我正在努力使API响应更具可读性，目前很难理解英语响应。你知道吗

import json, requests

response = requests.get("http://data.dublinked.ie/cgi-
bin/rtpi/realtimebusinformation?stopid=1341&routeid=49&format=json")

data = response.json()

print data

答案是这样的，它非常难看：（我想）格式化它，使它更可读，也许在一个列表或键：值对? B） 你如何从回复中只挑选某些信息？你知道吗

numberofresults: 2

errormessage:

u'37'}]

我很有可能在一个问题/答案上加倍，但我似乎找不到它！对不起的。 还有，u这个词我也不懂。你知道吗

提前谢谢大家

Answer 1

“u”代表unicode字符串。返回类型是键值（字典）数据类型

import json, requests
import pprint

response = requests.get("http://data.dublinked.ie/cgi-bin/rtpi/realtimebusinformation?stopid=1341&routeid=49&format=json")
data = response.json()

pprint.pprint(data)  #Better view
print data['numberofresults']  #Key-Value

Answer 2

python中的json库非常有用，尤其是在处理json对象时。我会特别关注json.dump文件以及json.dumps文件方法。如果你看看official documentation，json.dumps文件返回字符串并接受分隔符参数和缩进参数。你知道吗

import json, requests

response = requests.get("http://data.dublinked.ie/cgi-bin/rtpi/realtimebusinformation?stopid=1341&routeid=49&format=json")
print(json.dumps(response.json(), separators=(",",":"), indent=4)

如上所述，字符串前面的u表示unicode字符串，您现在可以放心地忽略它。你知道吗
