Can someone point me in the right direction to write this code please

Question

Hi guys,

I am having trouble writing this code I have like all the basic input prompts to get the input data from the user but how can I add all the input up to a total and then output messages?

Please enter the route:

Please enter the number of stops on this route:

How many passengers were waiting for the bus at stop #1? 5

How many passengers left the bus at stop #2? 3

How many passengers were waiting for the bus at stop #2? 4

How many passengers left the bus at stop #3? 2

This is the last stop. There should be 4 passengers leaving.

How many passengers left the bus at stop #3? 4

Route number: 999

Passengers left: 4

Answer 1

The type of value returned by input() function is string.
To do calculation with them, you need to cast them to numbers:

def number(s):
try:
if '.' in s:
return float(s)
else:
return int(s)
except:
return None

... use the above function to do that:

value = number(input('Enter a value? '))

... to get the most adapted numerical type ;)

However, what do you want to do with your last lines of code? ( from declaration/assignation of 'a' and 'b' arrays )
What should be the purpose of your ( unused ) sum() function? ( actually she return the concatenation of two inaccessible global variables: you need to defines parameters to your function to pass any list through them, or define your "static" lists so they are accessible inside the function scope -- declare them inside, or declare 'a' and 'b' with 'global' keyword )

Answer 2

This is your output... what's your code? or is it your "expected" output?
What is the purpose of the code to write? ( what to do with all these user entries ^^ )

Thnx @visph,
no this is not my output,

I have most of the user input prompts done I just need to add them up at the end

here is what i got so far

bus_route= 123
bus_route = input("Please enter the route number: ")
if input() != bus_route:
print("Invalid route number. Please enter a positive integer.")
else:

stops = input("Please enter the number of stops on this route: ")
stops = int(stops)

first = input("How many passengers were waiting for the bus at stop #1? ")
first = int(first)

first_stop = input("How many passengers left the bus at stop #2? ")
first_stop = int(first_stop)

second = input("How many passengers were waiting for the bus at stop #2? ")
second = int(second)

second_stop = input("How many passengers left the bus at stop #3? ")
second_stop= int(second_stop)

third = input("How many passengers were waiting for the bus at stop #3? ")
third = int(third)

third_stop = input("How many passengers left the bus at stop #4? ")
third_stop= int(third_stop)

fourth = input("How many passengers were waiting for the bus at stop #4? ")
fourth = int(fourth)

fourth_stop = input("How many passengers left the bus at stop #5? ")
fourth_stop= int(fourth_stop)

fifth = input("This is the last stop. There should be + 'fourth_stop' passengers leaving at this stop")
fifth = int(fifth)

total_stop= first+second+third+fourth+fifth
print(total_stop)

a = [first_stop, second_stop, third_stop, fourth_stop]
b = [first, second, third, fourth, fifth]
def sum():
return (a+b)

Answer 4

I give that a go.
Thank you @visph
