I'm scraping a website in order to get address which I then am running through the MapBox geo-coder using their API.

The basic code is:

geocoder = mapbox.Geocoder(access_token='my_token')


response = geocoder.forward(address)
result = response.json()

I'm feeding in the addresses on the fly, as I scrape the webpage.

When I print result, my geo-code output is:

I then get the coordinates of the output, using:

coordinates = result['features'][1]['center']

However, when I try and print coordinates (geo-coordinates) for this same output, I get:

[-122.41, 37.78]

How can I get this to print the full float of the coordinates? Currently, it seems to be rounding the numbers to two decimal places. I've tried using: print ["%0.6f" % i for i in coordinates] but this just adds zeros to the end of it. Thanks.

That is the full float of those coordinates.

If you examine the json, you'll see that for only the second center (at index 1) there are two decimal places. The rest have at least six decimal places.

running:

for coordinates in result["features"]:
    print(coordinates["center"])

resulted in:

[-122.408767, 37.775679]
[-122.41, 37.78]
[-120.351259, 36.149281]
[-121.270558, 37.935765]
[-121.3078506, 38.5879294]
