How do you get the last say 20 "Close price" values from python-binance using the "Get Historical Kline/Candlesticks" function?

Question

I am trying to make a list from the last few "close price" values on binance. This is the code that I currently have.

from binance.client import Client
client= Client(API_KEY,API_SECRET)
klines = client.get_historical_klines("BTCUSDT", 
Client.KLINE_INTERVAL_1MINUTE, "1 day ago UTC")
print(klines)

The output is multiple lists described as follows:

[
  [
    1499040000000,      // Open time
    "0.01634790",       // Open
    "0.80000000",       // High
    "0.01575800",       // Low
    "0.01577100",       // Close
    "148976.11427815",  // Volume
    1499644799999,      // Close time
    "2434.19055334",    // Quote asset volume
    308,                // Number of trades
    "1756.87402397",    // Taker buy base asset volume
    "28.46694368",      // Taker buy quote asset volume
    "17928899.62484339" // Ignore.
  ]
]

Here is an example of the output with the middle removed:

I want to make a list consisting of the 5th [4] value of the last say 20 lists.

Not sure if there is a better function to use in python.

Answer 1

"open = [float(entry[1]) for entry in k_lines]"

Answer 2

you can access to each items and properties by using : klines[i][j]
