合并两个列表以创建一个列表，其中包含两个列表的项目作为列表

Question

我想合并两个列表：

lon: [14.21055347, 14.21055347, 16.39356558, 16.39356558, 14.21055347]

lat: [48.22824817, 48.22824817, 48.18617251, 48.18617251, 47.65823679]

获得：

coordinates: [[14.21055347, 48.22824817], [14.21055347, 48.22824817], [16.39356558, 48.18617251], [16.39356558, 48.18617251], [14.21055347, 47.65823679]]

对于非常长的 lon/lat 列表，如何有效地完成此操作？

感谢您的帮助！

Answer 1

为此您需要使用 zip() 函数。像大多数 python3 内置函数一样，它使用迭代器，因此性能非常好。

>>> lon = [14.21055347, 14.21055347, 16.39356558, 16.39356558, 14.21055347]
>>> lat = [48.22824817, 48.22824817, 48.18617251, 48.18617251, 47.65823679]
>>> coordinates = zip(lon, lat)
>>> print(list(coordinates))
[(14.21055347, 48.22824817), (14.21055347, 48.22824817), (16.39356558, 48.18617251), (16.39356558, 48.18617251), (14.21055347, 47.65823679)]

Answer 2

我不太确定我是否正确理解了你的问题，但如果你想匹配这两个数组，只需执行：

名称 = [array1, array2]

Answer 3

您可以利用 map built-in function as well as lambda expressions。

lon = [14.21055347, 14.21055347, 16.39356558, 16.39356558, 14.21055347]
lat = [48.22824817, 48.22824817, 48.18617251, 48.18617251, 47.65823679]

coordinates = list(map(lambda x, y: [x, y], lon, lat))

print(coordinates)
>>> [[14.21055347, 48.22824817], [14.21055347, 48.22824817], [16.39356558, 48.18617251], [16.39356558, 48.18617251], [14.21055347, 47.65823679]]

Answer 4

lon = [14.21055347, 14.21055347, 16.39356558, 16.39356558, 14.21055347]
lat = [48.22824817, 48.22824817, 48.18617251, 48.18617251, 47.65823679]

coordinates = [[i,j] for i,j in zip(lon, lat)]

print(coordinates)

Answer 5

只需使用地图功能

lon = [14.21055347, 14.21055347, 16.39356558, 16.39356558, 14.21055347]
lat = [48.22824817, 48.22824817, 48.18617251, 48.18617251, 47.65823679]
coordinates = list(map(lambda x,y: [x,y], lon,lat))
print(coordinates)

输出是：- [[14.21055347, 48.22824817], [14.21055347, 48.22824817], [16.39356558, 48.18617251], [16.39356558, 48.18617251], [14.21055347, 47.651][3]8

Map 将函数作为输入，因此必须引入 lambda 函数
