比较一个列表中的值 [英] Compare values in one list

问题描述

对于学校，我需要完成一项作业，但是我不知道该怎么办.

For school I have an assignment to make, but I don't know what to do.

我有两个工作站，一个beginStation(开始)和一个eindStation(结束).首先，我必须检查它们是否在电台列表中.一切顺利. 但是现在我必须检查eindStation是否在同一列表中，位于beginStation之后.

I have two stations, a beginStation (start) and eindStation (end). First I had to check whether they are or are not in a list of stations. This went fine. Now however I have to check if in that same list the eindStation comes after the beginStation.

 stations_place = {"Schagen" : 1, "Heerhugowaard" : 2, "Alkmaar" : 3, "Castricum" : 4, "Zaandam" : 5, "Amsterdam Sloterdijk" : 6, "Amsterdam Centraal" : 7, "Amsterdam Amstel" : 8, "Utrecht Centraal" : 9, "'s-Hertogenbosch" : 10, "Eindhoven" : 11, "Weert" : 12, "Roermond" : 13, "Sittard" : 14, "Maastricht" : 15}

 eindStation = str(input("What is your end station? "))

 if eindStation in stations_place:
     print("good") #just to check if the code does it's job here
 else :
     print("This station isn't available, endstation is: Maastricht")

 if eindStation >= beginStation in stations_place.values:
     print("good") #just to check if the code does it's job here
 else:
     print("This station isn't available, endstation is: Maastricht")

我希望你们能帮助我.预先感谢！

I hope you guys can help me out. Thanks in advance!

推荐答案

您需要先请求beginStation.
这是一种方法:

You need to ask for the beginStation to begin with.
Here is one way:

stations_place = {"Schagen" : 1, "Heerhugowaard" : 2, "Alkmaar" : 3, "Castricum" : 4, "Zaandam" : 5, "Amsterdam Sloterdijk" : 6, "Amsterdam Centraal" : 7, "Amsterdam Amstel" : 8, "Utrecht Centraal" : 9, "'s-Hertogenbosch" : 10, "Eindhoven" : 11, "Weert" : 12, "Roermond" : 13, "Sittard" : 14, "Maastricht" : 15}
eindStation = str(input("What is your end station? "))

if eindStation in stations_place:
    print("good") #just to check if the code does it's job here
else :
    print("This station isn't available, endstation is: Maastricht")
beginStation = str(input("What is your Starting station? "))
if stations_place[eindStation] >= stations_place[beginStation]:
    print("good") #just to check if the code does it's job here
else:
    print("This station isn't available, endstation is: Maastricht")

> =实际上应该是>，因为没人想从a到a:)

That >= should really be > as no one wants to travel from a to a :)
