Как в Python вычислить ближайшие точки по имеющимся GPS-координатам?

from math import sin, cos, sqrt, atan2, radians

resturants = [[34.146263,-118.268293, 'Ресторан #1'],[34.152159,-118.246821, 'Ресторан #2'],[34.125732,-118.244208, 'Ресторан #3'],[34.132126,-118.233931, 'Ресторан #4']] 
R = 6373.0
mylatitute = 34.145979
mylongtitute = -118.254809
def findDist(lat1, lon1, lat2, lon2):
  global R
  lat1 = radians(lat1)
  lon1 = radians(lon1)
  lat2 = radians(lat2)
  lon2 = radians(lon2)

  dlon = lon2 - lon1
  dlat = lat2 - lat1

  a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
  c = 2 * atan2(sqrt(a), sqrt(1 - a))
  return R * c

def minDist():
  closeDist = 0
  name = ''
  for location in resturants:
    distance = findDist(mylatitute, mylongtitute, location[0], location[1]) 
    if(closeDist==0):
      closeDist = distance
      name = location[2]
    elif(closeDist>distance):
      closeDist = distance
      name = location[2]
    else:
      continue
  closeDist = round(closeDist, 2)
  print('Ближайший ресторан '+name+' находится в '+str(closeDist)+' км отсюда')
minDist()
