将坐标中的值分为横纵坐标数组x与y：(-2.0, 1.9800000000000035) (-1.99, 1.9800000000000035) (-1.98, 1.9800000000000035) (-1.97, 1.9800000000000035) (-1.96, 1.9800000000000035) (-1.95, 1.9800000000000035) (-1.94, 1.9800000000000035) (-1.93, 1.9800000000000035) (-1.92, 1.9800000000000035) (-1.91, 1.9800000000000035) (-1.9, 1.9800000000000035) (-1.89, 1.9800000000000035) (-1.88, 1.9800000000000035) (-1.8699999999999999, 1.9800000000000035) (-1.8599999999999999, 1.9800000000000035) (-1.8499999999999999, 1.9800000000000035) (-1.8399999999999999, 1.9800000000000035) (-1.8299999999999998, 1.9800000000000035) (-1.8199999999999998, 1.9800000000000035) (-1.8099999999999998, 1.9800000000000035) (-1.7999999999999998, 1.9800000000000035) (-1.7899999999999998, 1.9800000000000035) (-1.7799999999999998, 1.9800000000000035) (-1.7699999999999998, 1.9800000000000035) (-1.7599999999999998, 1.9800000000000035) (-1.7499999999999998, 1.9800000000000035) (-1.7399999999999998, 1.9800000000000035) (-1.7299999999999998, 1.9800000000000035)

可以使用Python的列表切片来将给定的坐标字符串转换为横纵坐标数组。具体操作如下：

coordinates = [(-2.0, 1.9800000000000035), (-1.99, 1.9800000000000035), (-1.98, 1.9800000000000035), (-1.97, 1.9800000000000035), (-1.96, 1.9800000000000035), (-1.95, 1.9800000000000035), (-1.94, 1.9800000000000035), (-1.93, 1.9800000000000035), (-1.92, 1.9800000000000035), (-1.91, 1.9800000000000035), (-1.9, 1.9800000000000035), (-1.89, 1.9800000000000035), (-1.88, 1.9800000000000035), (-1.8699999999999999, 1.9800000000000035), (-1.8599999999999999, 1.9800000000000035), (-1.8499999999999999, 1.9800000000000035), (-1.8399999999999999, 1.9800000000000035), (-1.8299999999999998, 1.9800000000000035), (-1.8199999999999998, 1.9800000000000035), (-1.8099999999999998, 1.9800000000000035), (-1.7999999999999998, 1.9800000000000035), (-1.7899999999999998, 1.9800000000000035), (-1.7799999999999998, 1.9800000000000035), (-1.7699999999999998, 1.9800000000000035), (-1.7599999999999998, 1.9800000000000035), (-1.7499999999999998, 1.9800000000000035), (-1.7399999999999998, 1.9800000000000035), (-1.7299999999999998, 1.9800000000000035)]

x = [coord[0] for coord in coordinates]
y = [coord[1] for coord in coordinates]

print(x)
print(y)

输出结果为：
