xml - How can I edit a JSON file using Python? -

-

i've looked @ several questions , made appropriate changes, python script still isn't working. still new python apologize if i'm making simple mistake...

i'm sending xml response webpage display value json file. tested xml portion of script , works fine - when add code edit json file, xml response doesn't load. here's i've got - doing wrong?

#!/usr/bin/env python  import cgi import cgitb import json   open('../../../var/www/data.json', 'r+') f:     json_data = json.load(f)     json_data[0]['a'] = '7'     f.seek(0)     f.write(json.dumps(json_data))     f.truncate()  open('../../../var/www/data.json') data_file:         data = json.load(data_file)  cgitb.enable()   print "content-type: text/xml"      print # blank line, end of headers print "<?xml version='1.0' encoding='utf-8' ?><inputs><data>"+data[0]["a"]+"</data></inputs>"

i tried this...but didn't work either:

#!/usr/bin/env python  import cgi import cgitb import json  open('../../../var/www/data.json', 'r') f:     json_data = json.load(f)     json_data[0]["a"] = "7"  open('../../../var/www/data.json', 'w') f     f.write(json.dumps(json_data))  open('../../../var/www/data.json') data_file:          data = json.load(data_file)  cgitb.enable()    print "content-type: text/xml"      print # blank line, end of headers print "<?xml version='1.0' encoding='utf-8' ?><inputs><data>"+data[0]["a"]+"</data></inputs>"

and here json file:

[     {         "a": "11",         "b": "4",         "c": "",         "d": "basement",         "e": "digital",         "f": "",         "g": "",         "h": "",         "i": "",         "j": "",         "k": "",         "l": "",         "m": "",         "n": "on",         "o": "off",         "p": "1"     },     {         "a": "11",         "b": "3",         "c": "",         "d": "silver",         "e": "digital",         "f": "",         "g": "",         "h": "",         "i": "",         "j": "",         "k": "",         "l": "",         "m": "",         "n": "on",         "o": "off",         "p": "1"     },     {         "a": "12",         "b": "3",         "c": "",         "d": "bench",         "e": "digital",         "f": "",         "g": "",         "h": "",         "i": "",         "j": "",         "k": "",         "l": "",         "m": "",         "n": "on",         "o": "off",         "p": "1"     } ]

you should include error/console output next time.

in second file:

  • line 11 missing : @ end of line

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
