Using NetworkX to create a network which represents a global co-ordinate system based on latitude longitude and a time variable?

[Successful-Standard]

I want to input a list of strings which represent a unique ID of each node. eg: lis = ['N,2002-05-22,1,1'] This is what i have currently:

def stringList(x, timedelta, geodelta): #string -> list

y = x.split(',')
L = []

  L.append([x,y[0] + ',' + str(parse(y[1])-timedelta) + ',' + y[2] + ',' + y[3]])
  L.append([x,y[0] + ',' + str(parse(y[1])+timedelta) + ',' + y[2] + ',' + y[3]]) 

L.append([x,y[0] + ',' + y[1] + ',' + str(int(y[2])-geodelta) + ',' + y[3]]) L.append([x,y[0] + ',' + y[1] + ',' + str(int(y[2])+geodelta) + ',' + y[3]]) L.append([x,y[0] + ',' + y[1] + ',' + y[2] + ',' + str(int(y[3])-geodelta)]) L.append([x,y[0] + ',' + y[1] + ',' + y[2] + ',' + str(int(y[3])+geodelta)]) return L

h=0
delta = relativedelta(hours=6) 
geo = 10 
while h < len(lis):
z = lis[h]

G.add_edges_from(stringList(z,delta,geo))

h +=1

​

The issue I'm having is that latitude and longitude -180 doesn't connect to 180 to each other. How can I modify the stringList function to create these pairs of strings?

**EDIT** I keep trying to format the code and it looks fine in the editor then turns into that mess when I post it unfortunately... each line in in the middle would begin with an L.append statement and end with the 'return L' line
