Scraped youtube comments amount and real amount are different

Im new to Python and Im trying to code a commentscraper for youtube with the most important informations, which I put in a JSON-file. But the my amount of comments and replys is not the same as on Youtube. I don't know, where my error is. I recognized, that it doesn't write any data in the files, if there are less than 20 comments, but I don't know, where I have to change something...
Example:
https://youtu.be/Re1m9O7q-9U here I get 102, but it should be 107
https://youtu.be/Q9Y5m1fQ7Fk here I get 423, but it should be 486

I am trying to split first whole text, but there I met another problem is to match keys to values depending on '=' sign. Also there might be some keys with empty values. For ex.:
type = INREQ channel = sid = duration = 1.333 (to get to know that there is an empty value, you need to pay attention on number of spaces. Usually there is 1 space between prev.value and next key). So this example should look like this:
{
"type":"INREQ",
"channel":"",
"sid":"",
"duration":"1.333"
}
Thanks ahead!
Here, one thing pass for duplicate key about "$sid":"msid_1591844511335516_KRRNBSLH2FS"

you can try regulation in python.
here is what i write, it works for your problem.
for convenience i deleted string before "ext_ref...",you can directly truncate the raw string.

Proper way to format date for Fedex API XML

I have a Django application where I am trying to make a call to Fedex's API to send out a shipping label for people wanting to send in a product for cash. When I try to make the call though it says there is a data validation issue with the Expiration field in the XML I am filling out. I swear this has worked in the past with me formatting the date as "YYYY-MM-DD", but now it is not. I read that with Fedex, you need to format the date as ISO, but that is also not passing the data validation. I am using a python package created to help with tapping Fedex's API.
Django view function for sending API Call

Python: Get data through Thingspeak

I want to capture the sensor data through thingspeak.
I used the url provided with the api key in the browser:
http://api.thingspeak.com/update?key=MYKEY&field1=25&field2=75
I expect it will return field1 and field2, but the result below shows only the value of field1.
"channel":{
"id":202242,
"name":"DHT11",
"latitude":"0.0",
"longitude":"0.0",
"field1":"Temperature ( degC ) 1",
"field2":"Humidity ( % )",
"created_at":"2016-12-11T17:16:21Z",
"updated_at":"2016-12-11T18:12:00Z",
"last_entry_id":12
},
"feeds":[
{
"created_at":"2016-12-11T18:12:00Z",
"entry_id":12,
"field1":25
}
]
What step have I missed?
Try this approach:
Here you make request using APIs. You will find various API requests here.
import urllib2
import json
import time
READ_API_KEY=' '
CHANNEL_ID= ' '
while True:
TS = urllib2.urlopen("http://api.thingspeak.com/channels/%s/feeds/last.json?api_key=%s" \
% (CHANNEL_ID,READ_API_KEY))
response = TS.read()
data=json.loads(response)
a = data['created_at']
b = data['field1']
c = data['field2']
d = data['field3']
print a + " " + b + " " + c + " " + d
time.sleep(5)
TS.close()

Generating Python soaplib stubs from WSDL

I'd like to generate a stub SOAP web service class using the Python soaplib module, based on an existing WSDL. The idea is to generate a mock for a third party web service.
Does any such code generator exist, or must we write our own?

Okay, I had a go at hacking my wsdl2interface (http://pypi.python.org/pypi/wsdl2interface) script to output soaplib code. I think I have something that works, though it's not pretty or especially well tested.
I'll paste it here for the record. I could be persuaded to release it if someone needs it, though it's not exactly my best code. Note that it uses Suds' WSDL parser to generate soaplib code, which is a bit strange in itself.
Run like this:
$ wsdl2soaplib <url or filename of WSDL> > wsdl.py
The code (you'll need suds in your path, ideally in a virtualenv):
from StringIO import StringIO
import os.path
import sys
import textwrap
import keyword
import re
import suds.client
VALID_IDENTIFIER_RE = re.compile(r"[_A-Za-z][_A-Za-z1-9]*")
VALID_IDENTIFIER_FIRST_LETTER_RE = re.compile(r"[_A-Za-z]")
VALID_IDENTIFIER_SUBSEQUENT_LETTER_RE = re.compile(r"[_A-Za-z1-9]")

I have just created a github repository where I'm improving on optilude's script to make it work with soaplib2.0 and more. The link is https://github.com/fvieira/wsdl2soaplib.
