如何将字符串中的坐标拆分为较小列表的列表

一种选择是将coordinates方括号括起来并使用literal_eval()：

>>> from ast import literal_eval
>>> coordinates = "(-89.38477, 26.6671), (-89.38477, 27.13737), (-88.81348, 27.13737), (-88.81348, 26.6671)"
>>>
>>> data = list(literal_eval(coordinates))
>>> data
[(-89.38477, 26.6671), (-89.38477, 27.13737), (-88.81348, 27.13737), (-88.81348, 26.6671)]
