Thanks for your help - this is what I did - though it's probably obvious to most people reading this.
for rowcount in range (0, stn_count): row_durations.append(stn_list_short[rowcount]) for colcount in range (0, stn_count): # 3. Determine Station pairs for API query query_origin_stop = stn_list_long[rowcount] query_destination_stop = stn_list_long[colcount] # 4. Paths for determining duration. "station x = station x" has journey time 0 # 4a. Stations are SAME ....etc. and this part works! I am now stuck on something else though, but I'll start a new topic for that.
