Question

I have some data that I’m retrieving from a data feed as text. For example, I receive the data like the following:

1105488000000, 34.1300, 34.5750, 32.0700, 32.2800\r\n
1105574400000, 32.6750, 32.9500, 31.6500, 32.7300\r\n
1105660800000, 36.8250, 37.2100, 34.8650, 34.9000\r\n

etc.

(This is stock data, where the first column is the timestamp, the next columns are the open, high, low, and close price for the time period.)

I want to convert this into a json such as the following:

[
[1105488000000, 34.1300, 34.5750, 32.0700, 32.2800], 
[1105574400000, 32.6750, 32.9500, 31.6500, 32.7300], 
[1105660800000, 36.8250, 37.2100, 34.8650, 34.9000],
...

The code that I’m using is:

  lines = data.split("\r\n");
  output = []
  for line in lines:
     currentLine = line.split(",")
     currentLine = [currentLine[0] , currentLine[1] , currentLine[2], currentLine[3], currentLine[4]]
     output.append(currentLine)


  jsonOutput = json.dumps(output)

However, when I do this, I’m finding that the values are:

[
["1105488000000", "34.1300", "34.5750", "32.0700", "32.2800"], 
["1105574400000", "32.6750", "32.9500", "31.6500", "32.7300"], 
["1105660800000", "36.8250", "37.2100", "34.8650", "34.9000"],

Is there anyway for me to get the output without the double quotes?

Answer 1

Pass the data through the int() or float() constructors before outputting in order to turn them into numbers.
