How to add string in specific positions in geojson object

i have the below posted geojson mentioned in geojson_1 section below. i want to add to it "geometry":{ and }, so that to appear as follows
{"geometry":{"type":"Polygon","coordinates":[[[1216374.67364018,6563498.44078949],[1216387.86261675,6563523.87797899],[1216397.66970116,6563548.2905649],[1216424.17569103,6563588.32082324],[1216458.19258303,6563622.16452455],[1216498.32084288,6563648.42909789],[1216542.90943577,6563666.03380959],[1216590.12376481,6563674.25425166],[1216638.02117068,6563672.7521636],[1216684.63088244,6563661.58935797],[1216728.03512655,6563641.225175],[1216752.29181681,6563626.67066235],[1216787.17700448,6563601.12371718],[1216816.83970763,6563569.63465531],[1216831.39332728,6563551.03748989],[1216838.2508451,6563541.8226918],[1216897.47283376,6563458.0765492],[1216918.74007329,6563421.44644481],[1216933.156564,6563381.60258193],[1216940.26085904,6563339.82061228],[1216939.82562707,6563297.43819918],[1216931.86491641,6563255.81218836],[1216907.60647856,6563170.91644364],[1216887.20280767,6563121.46139137],[1216856.24799209,6563077.86160203],[1216821.48046704,6563039.0529759],[1216799.23490474,6563017.28929875],[1216753.95673639,6562978.48086898],[1216737.29066155,6562965.4435638],[1216673.22488836,6562919.79826372],[1216644.73178636,6562899.22061724],[1216601.13622245,6562874.31962206],[1216562.32695185,6562857.3410734],[1216556.56069412,6562854.90900462],[1216549.97837146,6562852.23502385],[1216545.77480552,6562849.58841453],[1216504.75306873,6562829.03095075],[1216487.0229317,6562822.21187019],[1216482.65368148,6562820.3796627],[1216478.79578194,6562814.49158384],[1216462.95127963,6562793.04723497],[1216450.44559886,6562777.97698661],[1216448.65520854,6562774.19751598],[1216429.39331353,6562740.84427663],[1216404.99213055,6562711.06486155],[1216382.3528849,6562687.61801865],[1216357.97638417,6562665.64947943],[1216339.38004804,6562651.09634054],[1216299.24217837,6562625.743469],[1216254.86196793,6562608.94292463],[1216208.02902037,6562601.37212065],[1216160.63182011,6562603.33631786],[1216114.58159971,6562614.75632195],[1216071.73529105,6562635.17167463],[1216033.82066317,6562663.75921023],[1216002.36666225,6562699.36623124],[1215978.64176027,6562740.55696848],[1215963.60279766,6562785.67045603],[1215957.85638339,6562832.88749107],[1215961.63441126,6562880.30398198],[1215963.25125904,6562889.19806131],[1215964.03213898,6562893.28933659],[1215968.1319511,6562913.79137984],[1215972.03222389,6562937.19708669],[1215977.28745991,6563016.79645952],[1215971.45390521,6563048.0427099],[1215969.39172682,6563061.09023781],[1215963.73069651,6563104.75131293],[1215962.06592533,6563123.22251112],[1215960.00953034,6563163.6421848],[1215954.35640427,6563213.80082903],[1215954.63230125,6563269.34572034],[1215960.29082704,6563315.43307246],[1215970.70253119,6563361.57391952],[1215982.82982632,6563397.95907391],[1216001.20120538,6563439.38870108],[1216027.10825421,6563476.54992802],[1216059.60193364,6563508.08124916],[1216097.4918555,6563532.82739871],[1216139.38989254,6563549.8816932],[1216183.76104002,6563558.61926572],[1216228.97966418,6563558.71997125],[1216273.38907516,6563550.18012236],[1216287.1346647,6563546.13717455],[1216332.92682121,6563527.24586381],[1216373.78586258,6563499.1986745],[1216374.67364018,6563498.44078949]]]}}
to simpify it even more, i want to add "geometry":{ right after the the first curly bracket, and the } at the very end
i attmepted the following:
asString = asString[:2] + "geometry:" + asString[2:]
asString = asString[:len(asString)] + "}" + asString[len(asString):]
but i am not getting the expected results

I'm going to assume that geojson_1 is available as a string in which case:
import json
output = {'geometry': json.loads(geojson_1)}
...will give you a dictionary with the structure you need.

It looks like plain json data, or a string representation of a dict (they wouldn't be any different in this case), did you consider wrapping the returned data in a new dict rather than manipulating it as a string?
import json
# Assume this returns the geojson as text
geojson = json.loads(get_geojson())
geojson = {"geometry": geojson}
print(json.dumps(geojson))

I get the expected result using the following:
'{"geometry":' + d + "}"
It adds the string {"geometry": to the string d and at the end }.
The variable dis:
d = '{"type":"Polygon","co (rest of json) ,6563498.44078949]]]}'
Or you can use the json library for this:
import json
data = json.loads(d) # note d is the same string as above, this can also be from a file or read file using json.load(FILE)
# Create your new object:
result = {'geometry': data}
# print you new json:
print( json.dumps(result, indent=2))
edit:
'"geometry":{' + d + "}"
Note that you get a string starting with geometry and a { and directly another { from you input json. This is not a correct dictionary nor a proper json format.
Result:
'"geometry":{{"type":"Polygon", ... ,6563498.44078949]]]}}'
(the dots are just the rest of your original json.

Finding multiple occuring of word in string in Python

So I have a string that contains data below
https://myanimelist.net/animelist/domis1/load.json?status=2&offset=0.
I want to find all 'anime_id' and put them into the list (only numbers).
I tried with find('anime_id'), but I can't do this for multiple occurings in the string.

Here is an example, how to extract anime_id from a json file called test.json, using built-in json module:
import json
with open('test.json') as f:
data = json.load(f)
# Create generator and search for anime_id
gen = (i['anime_id'] for i in data)
# If needed, iterate over generator and create a list
gen_list = list(gen)
# Print list on console
print(gen_list)

Your string is in json format, you can parse it with the builtin json module.
import json
data = json.loads(your_string)
for d in data:
print(d["anime_id"])

How to parameterize JSON object in a Python script

I am writing a test in Python where i am specifying the JSON sting in a parameter as follows :
json = '...[{"MemberOperand":{
"AttributeName":"TEST",
"Comparison":"=",
"Value":"Test"}
}]...'
In this example i have the value as "Test" however i want to run the test with several values. Could you guys tell me how can i parameterize The values of "Value"?

You can construct proper JSON:
import json
the_value = 'Test'
data = [{"MemberOperand": {
"AttributeName":"TEST",
"Comparison":"=",
"Value": the_value}
}]
json_text = json.dumps(data)

This is regular dictionary (nested) formatted as string -
def changer(x):
import json
d=json.loads(json.loads(json.dumps('[{"MemberOperand":{"AttributeName":"TEST","Comparison":"=","Value":"Test"}}]')))
d[0]['MemberOperand']['AttributeName']=x
return d
print changer('New_TEST')
Output-
[{'MemberOperand': {'Comparison': '=', 'AttributeName': 'New_TEST', 'Value': 'Test'}}]

Add function which return you different json string all the time by provided value as parameter:
def get_mock_json(value='Test'):
return '...[{"MemberOperand":{"AttributeName":"TEST","Comparison":"=","Value":%s}}]...'%value
print get_mock_json('test')
print get_mock_json('ttttttest')

Extracting data from a nested json structure in python

My json file looks like this:
{"07/01/2015-08/01/2015":
{"ABC": [
["12015618727", "2015-07-29 02:32:01"],
["12024079732", "2015-07-24 13:04:01"],
["12024700142", "2015-07-02 00:00:00"]
]
}
}
I want to extract the numbers 12015618727, 12024079732, 12024700142 from here in python.
I wrote this code:
import json
numbers=set()
input_file=open('filename', 'r')
json_decode=json.load(input_file)
for item in json_decode["07/01/2015-08/01/2015"]["ABC"]:
for j in item:
numbers.add(j[0])
print " ".join(str(x) for x in numbers)
But this doesn't print the numbers.

Python has a json parsing library, see https://docs.python.org/2/library/json.html for details.
Usage:
import json
text = open("file.txt", "r").read()
obj = json.loads(text)
where obj is a python native dict object with nested arrays and dicts.
Edit:
This is the code you want.
import json
numbers=set()
input_file=open('filename.json', 'r')
json_decode=json.load(input_file)
for item in json_decode["07/01/2015-08/01/2015"]["ABC"]:
numbers.add(item[0])
print " ".join(str(x) for x in numbers)
You iterated through each item (the two strings) and added the first letter of each string, hence 1 and 2. Next time, please provide the output you got.
Also, you should attempt to debug your code first. I added a print at the beginning of each loop, and that made the problem pretty clear.

How to remove commas, brackets in python using regular expression?

These are the contents of my text file (eg:abc.doc):
{'data': [{'name': 'abc'},{'name': 'xyz'}]}
After opening the file in python; how do i remove all the brackets, quotes and commas.
The final output should be:
data:
name:abc
name:xyz

Use ast.literal_eval() to turn it into a python structure, then print the values:
with open(r'd:\output1.doc', 'r') as inputfile:
inputstring = inputfile.read()
data = ast.literal_eval(inputstring)
for key, sublist in data.items():
print '{}:'.format(key)
for subdict in sublist:
for key, value in subdict.items():
print('{}:{}'.format(key, value))
For your example that results in:
>>> inputstring = "{'data': [{'name': 'abc'},{'name': 'xyz'}]}"
>>> import ast
>>> data = ast.literal_eval(inputstring)
>>> for key, sublist in data.items():
... print '{}:'.format(key)
... for subdict in sublist:
... for key, value in subdict.items():
... print '{}:{}'.format(key, value)
...
data:
name:abc
name:xyz
However: If you got this from the Facebook API, then you transcribed the format incorrectly. The Facebook API gives you JSON data, which uses double quotes (") instead:
{"data": [{"name": "abc"},{"name": "xyz"}]}
in which case you should use the json library that comes with Python:
import json
data = json.loads(inputstring)
# process the same way as above.
If you have a filename, you can ask the library to read straight from the file using:
data = json.load(filename) # note, no `s` after `load`.

Looks to me like you have json, which can be easily parsed using pyjson:
import json
obj=json.loads(u'''{'data': [{'name': 'abc'},{'name': 'xyz'}]}''')
Bob's your uncle now, innit?
