我不知道这个有什么问题,但是我完全搞不懂。
所以我有这段代码:
from model.Formulas import Formulas
f = open("coords_data.txt", "r")
line1 = f.readline()
line2 = f.readline()
orig = line1.split(';')
dest = line2.split(';')
origin = (orig[0] + ", " + orig[1].strip("\n"))
destination = (dest[0] + ", " + dest[1].strip("\n"))
print("Orig: " + str(origin))
print("Dest: " + str(destination))
total_dist = Formulas.calculateDistance(str(origin), str(destination))
# Formulas.calculateDistance()
导入代码为:
import math
class Formulas:
# 3959 # radius of the great circle in miles...some algorithms use 3956
# 6371 # radius in kilometers...some algorithms use 6367
# 3959 * 5280 # radius in feet
# 6371 * 1000 # radius in meters
@staticmethod
def calculateDistance(origin, destination, rounding=0):
lat1, lon1 = origin
lat2, lon2 = destination
radius = 6371 # km
dlat = math.radians(lat2 - lat1)
dlon = math.radians(lon2 - lon1)
a = math.sin(dlat / 2) * math.sin(dlat / 2) + math.cos(math.radians(lat1)) * math.cos(math.radians(lat2)) * math.sin(dlon / 2) * math.sin(dlon / 2)
c = 2 * math.atan2(math.sqrt(a), math.sqrt(1 - a))
d = radius * c
return round(d, rounding)
现在我希望从一个包含5057行坐标的大型列表中获取确切的总距离。因此,它需要计算所有距离之间的差异并返回一个大型数字(例如150公里)。
我收到的错误消息是:
ValueError:要拆分的值过多(预期2个)
文件中的坐标看起来像这样:
5114.8268;00457.9847
5114.8271;00457.9845
5114.8271;00457.9845

5114.8376;00457.9776
5114.8395;00457.9769
现在这些数据已经存储在文件中,但是将来会存储到数据库中。
我该怎么解决这个问题?如何消除这个错误?
