我想從json數據中提取一些信息。在下面的代碼中,我首先提取包含我想要的信息的json數據部分,然後將它存儲在一個文件中。然後我試圖打開這個文件,我得到了我的代碼後面的錯誤。你能幫我找到我錯在哪裏嗎?如何從json中提取信息?
import json
import re
input_file = 'path'
text = open(input_file).read()
experience = re.findall(r'Experience":{"positionsMpr":{"showSection":true," (.+?),"visible":true,"find_title":"Find others',text)
output_file = open ('/home/evi.nastou/Documenten/LinkedIn_data/Alewijnse/temp', 'w')
output_file.write('{'+experience[0]+'}')
output_file.close()
text = open('path/temp')
input_text = text.read()
data = json.load(input_text)
positions = json.dumps([s['companyName'] for s in data['positions']])
print positions
錯誤:
Traceback (most recent call last):
File "test.py", line 13, in <module>
data = json.load(input_text)

您嘗試加載爲字典的文檔可能不是JSON或Python文檔,或者它包含密鑰中的非法字符。 – 2013-04-25 10:48:42
