Hi guys,

I have a list with 6 items in it. I need to output how many items there are between 2 of the list items the users asks for.

How can I do this?

So for example this is my code:

Code

bus_stops= ['New York', 'Los Angeles', 'New Jersey ', 'Boston', 'Miami', 'Mexico']

start_station = input("What is your start destination")
end_station = input("What is your end destination")

totalstations = #STUCK HERE

I need to calculate how many bus stops there are between the user submitted start and end stations in the bus_stop list.

I've read that this is possible with the numPY library but I have't found a way to do it yet.

Code

bus_stops= ['New York', 'Los Angeles', 'New Jersey', 'Boston', 'Miami', 'Mexico']

start_station = input("What is your start destination")
end_station = input("What is your end destination")

start_pos = 0
end_pos = 0

for i in range(len(bus_stops)):
    if start_station == bus_stops[i]:
        start_pos = i + 1
        break

for i in range(len(bus_stops)):
    if end_station == bus_stops[i]:
        end_pos = i
        break

totalstations = end_pos - start_pos
print totalstations

[c x y k]

Loop until you have position of x, same with y.

y - x = d

Pretty self explanatory.

bus_stops= ['New York', 'Los Angeles', 'New Jersey', 'Boston', 'Miami', 'Mexico']

start_station = input("What is your start destination")
end_station = input("What is your end destination")

start_pos = 0
end_pos = 0

for i in range(len(bus_stops)):
    if start_station == bus_stops[i]:
        start_pos = i + 1
        break

for i in range(len(bus_stops)):
    if end_station == bus_stops[i]:
        end_pos = i
        break

totalstations = end_pos - start_pos
print totalstations

Thank you! that worked perfectly, I completely forgot about looping 😖

<?php 
bus_stops= ['New York', 'Los Angeles', 'New Jersey', 'Boston', 'Miami', 'Mexico']
start_station = 'New York'
end_station = 'Boston'
print (bus_stops.index(end_station)-1) - bus_stops.index(start_station)

Umm... There is no need for a loop here.

PHP Code


<?php 
bus_stops= ['New York', 'Los Angeles', 'New Jersey', 'Boston', 'Miami', 'Mexico']

start_station = input("What is your start destination")
end_station = input("What is your end destination")

total = max(bus_stops.index(start_station), bus_stops.index(end_station)) - min(bus_stops.index(start_station), bus_stops.index(end_station))

Thanks for this, it does make it simpler. 🤝
