पायथन - सीएसवी फ़ाइल को JSON

Question

में कनवर्ट करें मुझे एक सीएसवी फ़ाइल को पदानुक्रमित JSON ऑब्जेक्ट (अधिमानतः पायथन का उपयोग करके) में कनवर्ट करने की आवश्यकता है। मैंने सोचा कि मेरे पास (नीचे) स्क्रिप्ट जेएसओएन में परिवर्तित करने का सही काम करती है, लेकिन जावास्क्रिप्ट लाइब्रेरी जो मैं JSON डेटा को (D3.js) खिला रहा हूं, उसके साथ काम नहीं करती है। , अभी

मैं निम्नलिखित है कोड रिकर्सिवली श्रेणीबद्ध सरणी बनाता है:

मुझे लगता है कि यह तकनीकी रूप से JSON चश्मा फिट कर सकता है, लेकिन लाइब्रेरी मैं JSON डेटा को फ़ीड करने की कोशिश कर रहा हूं (D3.js) इसके साथ कुछ भी नहीं कर सकता है। क्या ऐसा इसलिए है क्योंकि तत्वों का क्रम बाहर निकलना है (यानी, "बच्चे" तत्व "नाम" तत्व से पहले आ रहा है)? क्या यह कुछ और बुनियादी है जो मैं कर रहा हूं?

(फ़ाइल जिसका संरचना मैं मैच के लिए here स्थित है कोशिश कर रहा हूँ।)

Answer 1

इस कार्य नहीं करेगा?

import json 

f = open('path/to/file','r') 

arr=[] 
headers = [] 

for header in f.readline().split(','): 
    headers.append(header) 

for line in f.readlines(): 
    lineItems = {} 
    for i,item in enumerate(line.split(',')): 
    lineItems[headers[i]] = item 
    arr.append(lineItems) 

f.close() 

jsonText = json.dumps(arr) 

print jsonText 

Answer 2

जेसन के लिए तत्वों का ऑर्डर महत्वपूर्ण नहीं है।

जो जेसन आप उत्पादन कर रहे हैं वह गलत है, हालांकि। उदाहरण जो आपने दिया है, जिसे आप मिलान करने का प्रयास कर रहे हैं, शीर्ष स्तर पर "विषय" कुंजी नहीं है। यह सिर्फ "नाम" => "भड़कना", और बच्चों की एक सूची दिखाता है। आपकी स्क्रिप्ट जेसन को "विषय" कुंजी के साथ उत्पन्न कर रही है।

subject_dict = {'name':subject,'type':'subject','children':branch_list} 

के बजाय

कोशिश

subject_dict = {'name':subject,'children':branch_list} 

मैं D3.js के बारे में पता नहीं है, इसलिए मैं यह नहीं कह सकते कि यह एक उद्देश्य यह है कि एक सटीक संरचना इस प्रकार की उम्मीद है।

युक्ति: जेसन ऑब्जेक्ट्स की संरचना की जांच करने के लिए एक अच्छा टूल http://jsoneditor.appspot.com है। बस अपनी स्ट्रिंग को वहां पेस्ट करें और "ट्रीव्यू पर जाएं" पर क्लिक करें। यह आपके पास जो कुछ है और आप जो आसानी से चाहते हैं उसके बीच मतभेद पाएंगे।

Answer 4

डी 3 जेएसओएन में मूल्य को डबल कोट्स में भी उम्मीद करता है। तो उदा। "स्तर": 3 "स्तर" होना चाहिए: "3"। जब आप गणना के लिए डी 3 में इस डेटा का उपयोग करते हैं तो इसे फिर से एक नंबर की आवश्यकता होगी, हालांकि आप इसका उपयोग कहां करते हैं, आप d3 कोड में data.xxx.yyy.level के बजाय + data.xxx.yyy.level का उपयोग कर सकते हैं। यह एक संख्या में है।
