在 Python 中打印浮点值（Mapbox 地理坐标）
Printing float values in Python (Mapbox geo-coordinates)
我正在抓取一个网站，以便使用他们的 API.
通过 MapBox 地理编码器获取我当时 运行 的地址
基本代码为：
geocoder = mapbox.Geocoder(access_token='my_token')
response = geocoder.forward(address)
result = response.json()
我在抓取网页时即时输入地址。
当我打印 result 时，我的地理代码输出是：

然后我得到输出的坐标，使用：
coordinates = result['features'][1]['center']
但是，当我尝试为同一输出打印 coordinates（地理坐标）时，我得到：
[-122.41, 37.78]
如何打印坐标的完整浮点数？目前，它似乎将数字四舍五入到小数点后两位。我试过使用： print ["%0.6f" % i for i in coordinates] 但这只是在它的末尾添加了零。谢谢。
这就是那些坐标的完整浮点数。
如果您检查 json，您会发现 只有 第二个 center（在索引 1 处）有两位小数。其余的至少有六位小数。
运行:
for coordinates in result["features"]:
print(coordinates["center"])
结果：
[-122.408767, 37.775679]
[-122.41, 37.78]
[-120.351259, 36.149281]
[-121.270558, 37.935765]
