So I was creating a script to list information from Google's V3 YouTube API and I used the structure that was shown on their Site describing it, so I'm pretty sure I'm misunderstanding something.
I tried using the structure that was shown to print JUST the Video's Title as a test
and was expecting that to print, however it just throws an error. Error is below
Here's what I wrote below
import sys, json, requests
vidCode = input('\nVideo Code Here: ')
url = requests.get(f'https://youtube.googleapis.com/youtube/v3/videos?part=snippet%2CcontentDetails%2Cstatistics&id={vidCode}&key=(not sharing the api key, lol)')
text = url.text
data = json.loads(text)
if "kind" in data:
print(f'Video URL: youtube.com/watch?v={vidCode}')
print('Title: ', data['snippet.title'])
else:
print("The video could not be found.\n")
This did not work, however if I change snippet.title to just something like etag the print is successful.
I take it this is because the Title is further down in the JSON List.
I've also tried doing data['items'] which did work, but I also don't want to output a massive chunk of unformatted information, it's not pretty lol.
Another test I did was data['items.snippet.title'] to see if that was what I was missing, also no, that didn't work.
Any idea what I'm doing wrong?
you need to access the keys in the dictionary separately.
import sys, json, requests
vidCode = input('\nVideo Code Here: ')
url = requests.get(f'https://youtube.googleapis.com/youtube/v3/videos?part=snippet%2CcontentDetails%2Cstatistics&id={vidCode}&key=(not sharing the api key, lol)')
text = url.text
data = json.loads(text)
if "kind" in data:
print(f'Video URL: youtube.com/watch?v={vidCode}')
print('Title: ', data['items'][0]['snippet']['title'])
else:
print("The video could not be found.\n")
To be clear, you need to access the 'items' value in the dictionary which is a list, get the first item from that list, then get the 'snippet' sub object, then finally the title.

I'm trying to do a little code that gets the emails (and other things in the future) from an API. But I'm getting "TypeError: list indices must be integers or slices, not str" and I don't know what to do about it. I've been looking at other questions here but I still don't get it. I might be a bit slow when it comes to this.
I've also been watching some tutorials on the tube, and done the same as them, but still getting different errors. I run Python 3.5.
Here is my code:
from urllib.request import urlopen
import json, re
# Opens the url for the API
url = 'https://jsonplaceholder.typicode.com/posts/1/comments'
r = urlopen(url)
# This should put the response from API in a Dict
result= r.read().decode('utf-8')
data = json.loads(result)
#This shuld get all the names from the the Dict
for name in data['name']: #TypeError here.
print(name)
I know that I could regex the text and get the result that I want.
Code for that:
from urllib.request import urlopen
import re
url = 'https://jsonplaceholder.typicode.com/posts/1/comments'
r = urlopen(url)
result = r.read().decode('utf-8')
f = re.findall('"email": "(\w+\S\w+)', result)
print(f)
But that seems like the wrong way to do this.
Can someone please help me understand what I'm doing wrong here?
data is a list of dicts, that's why you are getting TypeError while iterating on it.
The way to go is something like this:
for item in data: # item is {"name": "foo", "email": "foo#mail..."}
print(item['name'])
print(item['email'])
#PiAreSquared's comment is correct, just a bit more explanation here:
from urllib.request import urlopen
import json, re
# Opens the url for the API
url = 'https://jsonplaceholder.typicode.com/posts/1/comments'
r = urlopen(url)
# This should put the response from API in a Dict
result= r.read().decode('utf-8')
data = json.loads(result)
# your data is a list of elements
# and each element is a dict object, so you can loop over the data
# to get the dict element, and then access the keys and values as you wish
# see below for some example
for element in data: #TypeError here.
name = element['name']
email = element['email']
# if you want to get all names, you should do
names = [element['name'] for element in data]
# same to get all emails
emails = [email['email'] for email in data]
I am trying to make an API request to itunes to get songs by a particular artist and great a dictionary in JSON format with those songs. My below code is not returning any errors, but I am not sure where I am going wrong. Any help would be great. Also, I put comments next to some of the lines to help to further explain.
import json
import requests
def get_from_itunes(artist,songs):
base_url = "http://itunes.apple.com/search"
params_dict = {"term":bon+iver, "entity": music}
resp = requests.get(base_url, params=params_dict)
structured_resp_text = resp.text
python_obj_data_from_itunes = json.loads(structured_resp_text)
# the python object is a dictionary
itunes_dict_keys = python_obj_data_from_itunes.keys() # These keys are lists
for key in itunes_dict_keys:
print key # it's unicode. I have no clue how to proceed from here.
# I should be getting a dictionary
# And then getting to the key Track Name
file_obj = open("itunes_file.txt", "w") #wrote a file containing a JSON formatted string
# and then pasted that into the JSON editor
file_obj.write(python_obj_data_from_itunes + "\n")
file_obj.close()
return get_from_itunes()
I have this code below that I'm working on as part of an AI project. I'm looking to get tags that the user searches and return a url of a post with said tags.
from meya import Component
import requests
import json
API_URL = "https://e621.net/post/index.json?limit=1&tags=rating:s+order:random+{tag}"
class e621_call(Component):
"""Produces a e621 post based on the user's tags."""
def start(self):
tag = self.properties.get('tag') or \
self.db.flow.get('tag')
response = requests.get(API_URL.format(tag=tag))
img = response.json()['file_url']
message = self.create_message(text=img)
return self.respond(message=message, action="next")
Everything is fine up until I assign img to the file_url value, which brings up a
TypeError: list indices must be integers, not str
For the record, I am using meya.ai for this, and the packages are not the issue
Your API returns a dictionary inside a list. Get inside the list first then you can do what you wish with the dictionary.
response = requests.get(API_URL)
foo = json.loads(response.content)
file_url = foo[0].get('file_url')
If you plan on having multiple dictionaries returned inside the list, you can just loop through foo and find the multiple urls.
for d in foo:
print d.get('file_url')
Also, I prefer to not use .json() (As you may have noticed I didn't include it in my answer) because that way you can correctly check for the status_code first before proceeding. Otherwise if you get a 404 or a 500 for example, you will get errors.
if response.status_code == 200:
do stuff here
else:
print "Something is wrong"
I found a temporary workthrough, replacing response.json()['file_url'] with response.json()[0]['file_url'] works fine in the AI, although it still gives me the error.
My goal is to connect to Youtube API and download the URLs of specific music producers.I found the following script which I used from the following link: https://www.youtube.com/watch?v=_M_wle0Iq9M. In the video the code works beautifully. But when I try it on python 2.7 it gives me KeyError:'items'.
I know KeyErrors can occur when there is an incorrect use of a dictionary or when a key doesn't exist.
I have tried going to the google developers site for youtube to make sure that 'items' exist and it does.
I am also aware that using get() may be helpful for my problem but I am not sure. Any suggestions to fixing my KeyError using the following code or any suggestions on how to improve my code to reach my main goal of downloading the URLs (I have a Youtube API)?
Here is the code:
#these modules help with HTTP request from Youtube
import urllib
import urllib2
import json
API_KEY = open("/Users/ereyes/Desktop/APIKey.rtf","r")
API_KEY = API_KEY.read()
searchTerm = raw_input('Search for a video:')
searchTerm = urllib.quote_plus(searchTerm)
url = 'https://www.googleapis.com/youtube/v3/search?part=snippet&q='+searchTerm+'&key='+API_KEY
response = urllib.urlopen(url)
videos = json.load(response)
videoMetadata = [] #declaring our list
for video in videos['items']: #"for loop" cycle through json response and searches in items
if video['id']['kind'] == 'youtube#video': #makes sure that item we are looking at is only videos
videoMetadata.append(video['snippet']['title']+ # getting title of video and putting into list
"\nhttp://youtube.com/watch?v="+video['id']['videoId'])
videoMetadata.sort(); # sorts our list alphaetically
print ("\nSearch Results:\n") #print out search results
for metadata in videoMetadata:
print (metadata)+"\n"
raw_input('Press Enter to Exit')
The problem is most likely a combination of using an RTF file instead of a plain text file for the API key and you seem to be confused whether to use urllib or urllib2 since you imported both.
Personally, I would recommend requests, but I think you need to read() the contents of the request to get a string
response = urllib.urlopen(url).read()
You can check that by printing the response variable
I am trying to get the names of members of a group I am a member of. I am able to get the names in the first page but not sure how to go to the next page:
My Code:
url = 'https://graph.facebook.com/v2.5/1671554786408615/members?access_token=<MY_CUSTOM_ACCESS_CODE_HERE>'
json_obj = urllib2.urlopen(url)
data = json.load(json_obj)
for each in data['data']:
print each['name']
Using the code above I am successfully getting all names on the first page but question is -- how do I go to the next page?
In the Graph API Explorer Output screen I see this:
What change does my code need to keep going to next pages and get names of ALL members of the group?
The JSON returned by the Graph API is telling you where to get the next page of data, in data['paging']['next']. You could give something like this a try:
def printNames():
json_obj = urllib2.urlopen(url)
data = json.load(json_obj)
for each in data['data']:
print each['name']
return data['paging']['next'] # Return the URL to the next page of data
url = 'https://graph.facebook.com/v2.5/1671554786408615/members?access_token=<MY_CUSTOM_ACCESS_CODE_HERE>'
url = printNames()
print "====END OF PAGE 1===="
url = printNames()
print "====END OF PAGE 2===="
You would need to add checks, for instance ['paging']['next'] will only be available in your JSON object if there is a next page, so you might want to modify your function to return a more complex structure to convey this information, but this should give you the idea.
