从元组列表中，获取最接近给定值的元组 [英] from list of tuples, get tuple closest to a given value

问题描述

给出一个包含坐标的元组列表，我想找到哪个坐标最接近我在输入中给出的坐标:

Given a list of tuples containing coordinates, I want to find which coordinate is the closest to a coordinate I give in input:

cooList = [(11.6702634, 72.313323), (31.67342698, 78.465323)]
coordinate = (11.6702698, 78.113323)
takenearest(myList, myNumber)
...
(11.6702634, 72.313323)

请让我知道...

推荐答案

为您的数据

cooList = [(11.6702634, 72.313323), (31.67342698, 78.465323)]
coordinate = (11.6702698, 78.113323)

最短的Python答案是:

the shortest Pythonic answer is:

nearest = min(cooList, key=lambda x: distance(x, coordinate))

带有函数distance(a, b)，将点a和b之间的距离作为浮点数返回，您必须自己定义.

with a function distance(a, b) returning the distance between the points a and b as a float, which you have to define yourself.

现在，您必须决定如何计算距离:使用简单的a² + b² = c²，某些地理公式或专用的库.

Now you have to decide how you calculate the distance: using simple a² + b² = c², some geographical formula or a dedicated library.
