Using Python, how can i extract the field id
to a variable? Basicaly, i to transform this:
{
"accountWide": true,
"criteria": [
{
"description": "some description",
"id": 7553,
"max": 1,
"orderIndex": 0
}
]
}
to something like
print "Description is: " + description
print "ID is: " + id
print "Max value is : " + max

Assume you stored that dictionary in a variable called values. To get id
in to a variable, do:
idValue = values['criteria'][0]['id']
If that json is in a file, do the following to load it:
import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()
If that json is from a URL, do the following to load it:
import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()
To print ALL of the criteria, you could:
for criteria in values['criteria']:
for key, value in criteria.iteritems():
print key, 'is:', value
print ''
Assuming you are dealing with a JSON-string in the input, you can parse it using the json
package, see the documentation.
In the specific example you posted you would need
x = json.loads("""{
"accountWide": true,
"criteria": [
{
"description": "some description",
"id": 7553,
"max": 1,
"orderIndex": 0
}
]
}""")
description = x['criteria'][0]['description']
id = x['criteria'][0]['id']
max = x['criteria'][0]['max']
