Python: scrape a Javascript line

Question

I want to scrape a Javascript line that contains JSON data in Python. For example:

AH4RSearch.listingsJSON = $.parseJSON('{"properties":[{"Price":3695,"PriceFormatted":"3,695","Street":"9251 E Bajada Road"}');

I understand that after I can get the content of $.parseJSON I can use json.loads to store it in JSON format, but how do I get this content from the Javascript line?

it is only string/text so use standard string functions like split() and slicing [start:end] — furas

You might need re to extract the data out

import re
import json
your_js_string = """AH4RSearch.listingsJSON = $.parseJSON('{"properties":[{"Price":3695,"PriceFormatted":"3,695","Street":"9251 E Bajada Road"}');"""

m = re.search(r'\$\.parseJSON\(\'(.*?)\'\);', your_js_string)
print json.loads(m.group(1))
# oh, no, your json is broken

For Python it is only string so use standard string functions - like split() or slicing [start:end].

import json

text = '''AH4RSearch.listingsJSON = $.parseJSON('{"properties":[{"Price":3695,"PriceFormatted":"3,695","Street":"9251 E Bajada Road"}]}')'''

data = json.loads(text[39:-2])

print(data['properties'][0]['Price'])
