位置，经纬度，使用 python 解析

Question

我有一些字符串格式的 lon lat 点。 下面的示例数据。

现在，我想使用这些并将它们放入两个不同的列表中，分别用于 lon 和 lat。

但是，这些数据都是字符串格式，在单个列表结构中。 我认为这意味着我需要使用正则表达式？

我试过使用下面的代码，

re.sub("^(\+|-)?(?:90(?:(?:\.0{1,6})?)|(?:[0-9]|[1-8][0-9])(?:(?:\.[0-9]{1,6})?))$"
,"",exampledatalatlon[1])

但我无法让它工作。 鉴于我已经尝试过这些方法，有谁知道将其重新格式化为 integer 格式（int() 不起作用）的快速简便的方法？

干杯

Answer 1

example = '(150.11, 33.20)'
lat, lon = map( lambda x: int(float(x)), example[1:-1].split(',') )

>>> lat = 150
>>> lon = 33

Answer 2

import re
input_string = """
(150.32424, -234.4234242)
(242.42342, -42342.4242)
(-2424, 2424)
"""
result = re.findall(r"\((-?\d+(?:\.\d+)?), *(-?\d+(?:\.\d+)?)\)", input_string)

# Use this if you just want the integer parts
# result = re.findall(r"\((-?\d+)(?:\.\d+)?, *(-?\d+)(?:\.\d+)?\)", input_string)

long, lat =  zip(*map(lambda pair: map(float, pair), result))

print(long) 
(150.32424, 242.42342, -2424.0)

print(lat)
(-234.4234242, -42342.4242, 2424.0)

Answer 3

什么迈克尔。 让我知道这是否是您想要的。 此脚本获取您的输入字符串并将假定的数据点分隔到单独的列表中，并将它们转换为浮点数。
