如何修复 BLS API 示例 Python 代码中的“KeyError：“系列”？
[英]How do I fix 'KeyError: 'series' in BLS API sample Python code?
问题描述
I'm trying to replicate the "API Version 2.0 Python Sample Code" provided by the Bureau of Labor Statistics (BLS) on its website here , but receive "KeyError: 'series'" whenever I try to run it.
我正在尝试复制劳工统计局 (BLS) 在其网站上提供的“API 版本 2.0 Python 示例代码”，但每当我尝试运行它时都会收到“KeyError：'series'”。
import requests
import json
import prettytable
headers = {'Content-type': 'application/json'}
data = json.dumps({"seriesid": ['CUUR0000SA0','SUUR0000SA0'],"startyear":"2011", "endyear":"2014"})
p = requests.post('https://api.bls.gov/publicAPI/v2/timeseries/data/', data=data, headers=headers)
json_data = json.loads(p.text)
for series in json_data['Results']['series']:
x=prettytable.PrettyTable(["series id","year","period","value","footnotes"])
seriesId = series['seriesID']
for item in series['data']:
year = item['year']
period = item['period']
value = item['value']
footnotes=""
for footnote in item['footnotes']:
if footnote:
footnotes = footnotes + footnote['text'] + ','
if 'M01' <= period <= 'M12':
x.add_row([seriesId,year,period,value,footnotes[0:-1]])
output = open(seriesId + '.txt','w')
output.write (x.get_string())
output.close()
Here is the output:这是 output：
---------------------------------------------------------------------------
KeyError Traceback (most recent call last)
<ipython-input-21-b89f58b9b664> in <module>
3 p = requests.post('https://api.bls.gov/publicAPI/v2/timeseries/data/', data=data, headers=headers)
4 json_data = json.loads(p.text)
----> 5 for series in json_data['Results']['series']:
6 x=prettytable.PrettyTable(["series id","year","period","value","footnotes"])
7 seriesId = series['seriesID']
KeyError: 'series'
I don't understand the cause of this error.我不明白这个错误的原因。 Will you please help me figure it out and fix it?你能帮我弄清楚并修复它吗？ Many thanks!非常感谢！
