How to get total sum of nested list's total value in a while loop?

I am trying to get buy and sell orders from binance api(python-binance) which has a limit of 500 values.(500 ask,500 buy). I already can get this with creating 500 variables with index numbers but it seems to me there has to be a better way than to write 500 lines of code.
This is the code I am trying to make it happen.

there is 500 bids and 500 asks
after getting data I sum bids ands asks like this
I tried to make for loop but only could print this values cant sum it in for loop this is the code I tried:
sample output:
0.9315 18328.6

0.9342 272.3
0.9343 704.4
0.9344 3581.7
0.9345 3896.8
the first items are price second is quantity
I am trying to make a function that sum and divide avg.price and also want to know how many bids total and asks total.

Use the sum() function with a generator that gets the appropriate element of each list item.
binance_buy_demand = sum(float(x[1]) for x in alis['bids'])
binance_sell_demand = sum(float(x[1]) for x in alis['asks'])

You can sum in a for loop like this:
total_ask_volume = 0
total_bid_volume = 0
for i in range(0, 500):
total_ask_volume += float(alis["asks"][i][1])
total_bid_volume += float(alis["bids"][i][1])
print(total_ask_volume, total_bid_volume)
Another option is to skip the i index, and go through the values directly:
total_ask_volume = 0
for ask in alis["asks"]:
total_ask_volume += float(ask[1])
total_bid_volume = 0
for bid in alis["bids"]:
total_bid_volume += float(bid[1])
print(total_ask_volume, total_bid_volume)
This can sometimes be clearer, particularly in situations where you'd otherwise have multiple indexes (i, j, k and so on) which could get confusing.
As a side note, float often rounds in unintuitive ways; it probably doesn't matter in this particular circumstance, but in most situations involving money you probably want to use Decimal instead (or multiply by 100 and count whole numbers of cents).

How can I send a sms in Django?

I encountered a problem when trying to send sms using the SMSC service in Django project.
My Celery task for sending email and sms:
def order_created_retail(order_id):
# Task to send an email when an order is successfully created
order = OrderRetail.objects.get(id=order_id)
subject = 'Order №{}.'.format(order_id)
message_mail = 'Hello, {}! You have successfully placed an order{}. Manager will contact you shortly'.format(order.first_name, order.id)
message_sms = 'Your order №{} is accepted! Wait for operator call'
mail_sent = send_mail(
subject,
message_mail,
'email#email.com',
[order.email]
)
smsc = SMSC()
sms_sent = smsc.send_sms(
[order.phone],
str(message_sms)
)
return mail_sent, sms_sent
Email sends correctly, but for sms I get that error:
Task orders.tasks.order_created_retail[f05458b1-65e8-493b-9069-fbaa55083e7a] raised unexpected: TypeError('quote_from_bytes() expected bytes')
function from SMSC library:
def send_sms(self, phones, message, translit=0, time="", id=0, format=0, sender=False, query=""):
formats = ["flash=1", "push=1", "hlr=1", "bin=1", "bin=2", "ping=1", "mms=1", "mail=1", "call=1", "viber=1", "soc=1"]
m = self._smsc_send_cmd("send", "cost=3&phones=" + quote(phones) + "&mes=" + quote(message) + \
"&translit=" + str(translit) + "&id=" + str(id) + ifs(format > 0, "&" + formats[format-1], "") + \
ifs(sender == False, "", "&sender=" + quote(str(sender))) + \
ifs(time, "&time=" + quote(time), "") + ifs(query, "&" + query, ""))
# (id, cnt, cost, balance) или (id, -error)
if SMSC_DEBUG:
if m[1] > "0":
print("Сообщение отправлено успешно. ID: " + m[0] + ", всего SMS: " + m[1] + ", стоимость: " + m[2] + ", баланс: " + m[3])
else:
print("Ошибка №" + m[1][1:] + ifs(m[0] > "0", ", ID: " + m[0], ""))
return m
What am I doing wrong?
Thanks!

to solve this problem, I started investigating the functions that were giving out the error.
It turned out that I was passing an incorrect value. the function was expecting a string. And it took me a long time to figure out why editing didn't help.
It turns out that you have to RESET CELERY every time you make an edit.

How to dynamically create a JSON string?

I am trying to create a JSON string that I can send in a PUT request but build it dynamically. For example, once I am done, I'd like the string to look like this:
{
"request-id": 1045058,
"db-connections":
[
{
"db-name":"Sales",
"table-name":"customer"
}
]
}
I'd like to use constants for the keys, for example, for request-id, I'd like to use CONST_REQUEST_ID. So the keys will be,
CONST_REQUEST_ID = "request-id"
CONST_DB_CONNECTIONS = "db_connections"
CONST_DB_NAME = "db-name"
CONST_TABLE_NAME = "table-name"
The values for the keys will be taken from various variables. For example we can take value "Sales" from a var called dbname with the value "Sales".
I have tried json.load and getting exception.
Help would be appreciated please as I am a bit new to Python.

Create a normal python dictionary, then convert it to JSON.
raw_data = {
CONST_DB_NAME: getDbNameValue()
}
# ...
json_data = json.dumps(raw_data)
# Use json_data in your PUT request.

You can concat the string using + with variables.
CONST_REQUEST_ID = "request-id"
CONST_DB_CONNECTIONS = "db_connections"
CONST_DB_NAME = "db-name"
CONST_TABLE_NAME = "table-name"
request_id = "1045058"
db_name = "Sales"
table_name = 'customer'
json_string = '{' + \
'"' + CONST_REQUEST_ID + '": ' + request_id \
+ ',' + \
'"db-connections":' \
+ '[' \
+ '{' \
+ '"' + CONST_DB_NAME +'":"' + db_name + '",' \
+ '"' + CONST_TABLE_NAME + '":"' + table_name + '"' \
+ '}' \
+ ']' \
+ '}'
print json_string
And this is the result
python st_ans.py
{"request-id": 1045058,"db-connections":[{"db-name":"Sales","table-name":"customer"}]}

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()

PyParsing: Parsing Cisco's "show ip bgp"

I am trying to parse a string as below using PyParsing.
R1# show ip bgp
BGP table version is 2, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
> 10.1.1.0/24 192.168.1.2 0 0 200 i
Note that LocPrf value is empty but it can be a number.
ipField = Word(nums, max=3)
ipAddr = Combine(ipField + "." + ipField + "." + ipField + "." + ipField)
status_code = Combine(Optional(oneOf("s d h * r")) + ">" + Optional(Literal("i"))
prefix = Combine(ipAddr + Optional(Literal("/") + Word(nums,max=2)))
next_hop = ipAddr
med = Word(nums)
local_pref = Word(nums) | White()
path = Group(OneOrMore(Word(nums)))
origin = oneOf("i e ?")
This is the grammar.
g = status_code + prefix + next_hop + med + local_pref + Suppress(Word(nums)) + Optional(path) + origin
I just need to parse the Bold line. But this is not parsing it properly. It assigns Weight value to LocPrf.

Please look over the following code example (which I will include in the next pyparsing release). You should be able to adapt it to your application:
from pyparsing import col,Word,Optional,alphas,nums,ParseException
table = """\
12345678901234567890
COLOR S M L
RED 10 2 2
BLUE 5 10
GREEN 3 5
PURPLE 8"""
# function to create column-specific parse actions
def mustMatchCols(startloc,endloc):
def pa(s,l,t):
if not startloc <= col(l,s) <= endloc:
raise ParseException(s,l,"text not in expected columns")
return pa
# helper to define values in a space-delimited table
def tableValue(expr, colstart, colend):
return Optional(expr.copy().addParseAction(mustMatchCols(colstart,colend)))
# define the grammar for this simple table
colorname = Word(alphas)
integer = Word(nums).setParseAction(lambda t: int(t[0])).setName("integer")
row = (colorname("name") +
tableValue(integer, 11, 12)("S") +
tableValue(integer, 15, 16)("M") +
tableValue(integer, 19, 20)("L"))
# parse the sample text - skip over the header and counter lines
for line in table.splitlines()[2:]:
print
print line
print row.parseString(line).dump()
