[spider_pytthon]

HI All ,

i have a map of a city and this map contains of lots of station that we are usind for distributing medium and low voltages cables for electricity .
i want to write a code to know which cables are crossed the boundary of the city and gives this cables red colour then i want to know which station connected to this cables and another code to know how many cables get out of each station in the map.

i have coordinate of this city and coordinate of the station but is it possible,do we have code to find all stations in the city without giving it coordinate just a name of a general name for station and he find it by itself.

Thanks alot
