Looping through json.loads(response.text) with Python

i'm learning and would appreciate any help in this code.
The issue is trying to print the values in the data that are contained in one line of the JSON using Python.
import json
import requests
data = json.loads(response.text)
print(len(data)) #showing correct value
#where i'm going wrong below obviously this will print the first value then the second as it's indexed. Q how do I print all values when using seperate print statements when the total indexed value is unknown?
for item in data:
print(data[0]['full_name'])
print(data[1]['full_name'])
I tried without the index value this gave me the first value multiple times depending on the length.
I expect to be able to access from the JSON file each indexed value separately even though they are named the same thing "full_name" for example.

import json
import requests
data = json.loads(response.text)
print(len(data)) #showing correct value
for item in data:
print(item['full_name'])
#the below code will throw error.. because python index starts with 0
print(data[0]['full_name'])
print(data[1]['full_name'])
hope this help

Presuming data is a list of dictionaries, where each dictionary contains a full_name key:
for item in data:
print(item['full_name'])
This code sample from your post makes no sense:
for item in data:
print(data[0]['full_name'])
print(data[1]['full_name'])
Firstly it's a syntax error because there is nothing indented underneath the loop.
Secondly it's a logic error, because the loop variable is item but then you never refer to that variable.

Extract info when JSON when key changes in Python

I'm quite new to Python so please excuse me if my terminology is not 100% accurate or if this is quite simple
I currently have the code:
import requests
POINTS = requests.get('https://api.torn.com/market/?selections=pointsmarket&key=jtauOcpEwz0W0V5M').json()
POINTSA = POINTS['pointsmarket']
print (POINTSA)
I want to print the cost of the very first key. However, the number for the first key will always change.
At the time of posting the first key is 9765126 as seen here:
https://imgur.com/VRi8Owe
So the line would be (I think):
POINTSA = POINTS['pointsmarket'][9765126]['cost']
However in 5 minutes time, the 9765126 key will change to something else. How do I get it to print the 1st cost entry regardless of the first key?

Hi you can try the following sample of getting the keys as a list then getting the first index
keys = list(POINTS['pointsmarket'].keys()) # Get all keys and convert to a list
POINTS['pointsmarket'][keys[0]]['cost']

Iterating Sequentially on the URL when running a Python API

I'm trying to pull data from an API for a fantasy football project I'm working on. You can pull data on various players using the url: 'https://fantasy.premierleague.com/api/element-summary/i/' where i is a number that relates to a player and runs from 1 to 400 or so.
I wrote code that pulls this data for a specific player and stores it as a dataframe for future analysis using the code:
import pandas as pd
import json
import requests
from pandas.io.json import json_normalize
r = requests.get('https://fantasy.premierleague.com/api/element-summary/1/')
r_json = r.json()
r_df = pd.DataFrame(r_json['history'])
r_df.head()
And this works great. The issue is it's only for 1 player and there are lots of them, so what I want is a DataFrame that contains this data for all of the players. I figured I could use a for loop for this but I can't get it to work. I'm trying the code:
import pandas as pd
import json
import requests
from pandas.io.json import json_normalize
for i in range(5):
r = requests.get('https://fantasy.premierleague.com/api/element-summary/{}/'.format(i))
r_json = r.json()
r_df= pd.DataFrame(r_json['history'])
r_df.head()
Where I've put the logic in a for loop, but I get the error:
KeyError: 'history'
When I try to run this. Why does it not like the line r_df= pd.DataFrame(r_json['history']) when it's in a for loop when it's OK outside of one?
Any help appreciated!
Thanks!

This is because your loop is trying to query 'https://fantasy.premierleague.com/api/element-summary/0/' on the first iteration, which doesn't exist. (Or, rather, gives you the JSON {"detail": "Not found."}, which doesn't have a "history" key.)
The built-in range function generates integers starting from zero by default. Try changing the loop range to range(1, 5) instead. (Also note that the end of the range is exclusive, so this will give you integers from 1 to 4.)

A KeyError indicates that the dictionary does not have this specific key.
Your specific problem here is that the range() function is generating the following range: [0, 1, 2, 3, 4] because if you don't specify an initial value, it will take 0 as an initial value and stop at one short of the final value.
And so https://fantasy.premierleague.com/api/element-summary/0/ doesn't return anything.
To fix this change range(5) to range(1, 6).
Note: the syntax of the range() function is: range(starting_point, ending_point, step)

Web scraping with Python3, and string formatting ?

this script is meant to parse Bloomberg finance to find the GBP value during the day, this following script does that however when it returns you get this:
{'dateTime': '2017-01-17T22:00:00Z', 'value': 1.6406}
I don't want the dateTime, or the value text there. I don't know how to get rid of it. and when I try it gives me errors like this: list index out of range.
any answers will be greatly appreciated. here is the script (in python3):
import urllib.request
import json
htmltext = urllib.request.urlopen('https://www.bloomberg.com/markets/api/bulk- time-series/price/GBPAUD%3ACUR?timeFrame=1_DAY').read().decode('utf8')
data = json.loads(htmltext)
datapoints = data[1]['price']
print(datapoints)

This should work for you.
print (data[0]['price'][-1]['value'])
EDIT: To get all the values,
for data_row in data[0]['price']:
print data_row['value']
EXPLANATION: data[0] gets the first and only element of the list, which is a dict. ['price'] gets the list corresponding to the price key. [-1] gets the last element of the list, which is presumably the data you'll be looking for as it's the latest data point.
Finally, ['value'] gets the value of the currency conversion from the dict we obtained earlier.

Parsing JSON string/object in Python

I've recently started working with JSON in python. Now I'm passing a JSON string to Python(Django) through a post request. Now I want to parse/iterate of that data. But I can't find a elegant way to parse this data, which somehow I'm pretty sure exists.
data = request.POST['postformdata']
print data
{"c1r1":"{\"Choice\":\"i1\"}","c2r1":"{\"Bool\":\"i2\"}","c1r2":"{\"Chars\":\"i3\"}"}
jdata = json.loads(data)
print jdata
{u'c1r2': u'{"Chars":"i3"}', u'c1r1': u'{"Choice":"i1"}', u'c2r1': u'{"Bool":"i2"}'}
This is what was expected. But now when I want to get the values, I start running into problems. I have to do something like
mydecoder = json.JSONDecoder()
for part in mydecoder.decode(data):
print part
# c1r2 c1r1 c2r1 ,//Was expecting values as well
I was hoping to get the value + key, instead of just the key. Now, I have to use the keys to get values using something like
print jdata[key]
How do I iterate over this data in a simpler fashion, so that I can iterate over key, values?

To iterate key and value, you can write
for key, value in jdata.iteritems():
print key, value
You can read the document here: dict.iteritems

Just for others to help. In Python3 dict.iteritems() has been renamed to dict.iter()
