在Python中的浮点数列表中对数据进行分组

我正在从API接收以下订单数据:

myData = [[9656.37, 0.063], [9656.32, 0.688], [9656.21, 0.729], [9656.07, 0.618], [9656.01, 0.598], [9656.0, 0.917], [9655.92, 0.417], [9655.84, 0.403], [9655.81, 1.032], [9655.6, 1.394], [9655.5, 0.043], [9655.41, 0.6], [9655.32, 0.441], [9655.31, 3.359], [9655.29, 0.15], [9655.0, 11.463], [9654.89, 0.612], [9654.88, 0.613], [9654.87, 0.602], [9654.74, 0.382], [9654.69, 0.75], [9654.63, 8.106], [9654.62, 0.8], [9654.58, 0.12], [9654.44, 0.54], [9654.38, 0.311], [9654.33, 2.758], [9654.31, 0.72], [9654.25, 0.02], [9654.14, 4.0], [9654.0, 0.155], [9653.95, 0.642], [9653.91, 0.5], [9653.83, 0.063], [9653.81, 0.6], [9653.38, 0.05], [9653.34, 0.1], [9653.31, 0.207], [9653.3, 0.001], [9653.28, 0.008], [9653.25, 3.351], [9653.03, 10.0], [9653.02, 0.651], [9652.98, 0.105], [9652.92, 0.002], [9652.9, 3.589], [9652.82, 2.07], [9652.8, 1.25], [9652.7, 0.4], [9652.66, 5.5], [9652.5, 0.006], [9652.48, 0.01], [9652.4, 0.207], [9652.39, 2.799], [9652.21, 0.174], [9652.14, 0.063], [9652.12, 8.106], [9652.09, 1.591], [9652.07, 4.0], [9652.06, 0.16], [9652.0, 0.006], [9651.9, 0.858], [9651.5, 0.006], [9651.49, 0.207], [9651.45, 0.106], [9651.37, 0.001], [9651.28, 0.7], [9651.21, 0.001], [9651.2, 1.377], [9651.16, 0.613], [9651.07, 0.16], [9651.06, 0.64], [9651.01, 0.75], [9651.0, 1.001], [9650.99, 2.637], [9650.94, 0.063], [9650.93, 2.82], [9650.87, 0.098], [9650.77, 4.782], [9650.6, 0.001], [9650.59, 12.279], [9650.56, 0.008], [9650.4, 0.008], [9650.23, 0.622], [9650.21, 0.008], [9650.2, 0.008], [9650.1, 8.106], [9650.09, 0.5], [9650.05, 1.036], [9650.0, 7.573], [9649.89, 0.5], [9649.76, 2.461], [9649.68, 0.207], [9649.6, 0.016], [9649.48, 0.059], [9649.4, 0.008], [9649.3, 10.0], [9649.29, 0.651], [9649.25, 1.286], [9649.21, 0.008] .... ]

这只是数据的一部分,总列表很大,大约有999个元素。由于此列表不必要地太大,因此我在考虑减少它的方法,这是我想出的:

Grouping the data: instead of having 9656.37, 9656.32, 9656.21 i can have only 9656. This would receive the amount of data a lot. The problem with this, is that i would also need to sum the second elements of every element, so in this case (see the data above), 9656 = 0.063 + 0.688 + 0.729 + 0.598 + 0.917. Then, the same should be done with 9655 and so on.

I don't have high knowledge of Python yet, and every time i try to solve this i end up having a lot of for loops that make the code a mess, without getting closer to my expected output: [[9656, 3.613], [9655, 19.302]...]

是否有任何有关执行此特定任务的示例,一些内置功能或实践可以帮助我实现这一目标?任何形式的建议,不胜感激,谢谢
