Stupid question

[abradler]

Can someone tell me why my nothing happens when i execute my program. Here is my code and output:

total_cash=0
total_owed=0
total_candy=20
input_var=input("How many candies would you like? ")
if input_var == 1:
    total_cash = total_cash + 40
    total_candy = total_candy - 1
    print (total_cash)
    print (total_candy)

Hello!
The input is a string. So to compare against an integer you have to turn input_var to int.

total_cash=0
total_owed=0
total_candy=20

# the whole while is in case if the user inputs a letter or a symbol instead of an integer
while True:
    try:
        input_var=int(input("How many candies would you like? "))
    except ValueError:
        print('Incorect input!')

if input_var == 1: # or instead you can do if input_var == '1':
    total_cash = total_cash + 40
    total_candy = total_candy - 1
    print (total_cash)
    print (total_candy)

The code snippet, provided by wavic will result in infinite loop, because he missed one break statement. Otherwise his explanation is correct and valid.

This

while True:
   try:
       input_var=int(input("How many candies would you like? "))
   except ValueError:
       print('Incorect input!')

should be

while True:
   try:
       input_var=int(input("How many candies would you like? "))
       break
   except ValueError:
       print('Incorect input!')

However, there is no need for this

if input_var == 1:

you don't compare the user input to every possible value. Instead use the user input as variable in the calculations. Of course, you need to take care if available candles are enough to meet user buy request.

Well, I was in a hurry but this can't be an excuse. Thank you!
