An algorithm is designed to display a list of meteorological stations recorded during a weather monitoring expedition.
1 # ----- Global variables -----
2 METSTATIONS = ["North_Base", "East_Ridge", "South_Valley", "West_Coast"]
3
4 # ----- Subprograms -----
5 def displayStations (stationList):
6 for i in range (0, len (stationList)):
7 print (i, stationList[i])
8
9 # ----- Main Program -----
10 query = input ("Retrieve meteorological station names? (Y/N): ")
11 if ((query == "Y") or (query == "y")):
12 displayStations (METSTATIONS)
13 else:
14 print ("Program Terminated")
State the type of data structure used to hold the meteorological station names inside the variable METSTATIONS in this algorithm.
