Finding items in lists using the in operator

August 18, 2022

I created some code where I try to find elements in a list given by the user using the in operator.

productNums = []

nums = int(input("How many numbers should be in your list?"))

while nums > 0:
    productNums.append(input("Add a number: "))  
    nums -= 1

numFind = int(input("What number are you trying to find? "))

if numFind in productNums:
    print("This product number is in the list")
elif numFind not in productNums:
    print("Ahh, sorry. This product number is NOT in this list!")
else:
    print("Huh, you're confusing me now, check your numbers pal!")

When I run this, I get the outcome that the number is not in this list, even though it is in it. Can someone tell me what I am doing wrong?

>Solution :

As people said above, just small issue with you integers and strings.
This is your code working:
Be careful with the indentention, initially was a mess.

productNums = []

nums = int(input("How many numbers should be in your list?"))

while nums > 0:
    productNums.append(int(input("Add a number: ")))  
    nums -= 1

    numFind = int(input("What number are you trying to find? "))

    if numFind in productNums:
      print("This product number is in the list")
    elif numFind not in productNums:
      print("Ahh, sorry. This product number is NOT in this list!")
    else:
      print("Huh, you're confusing me now, check your numbers pal!")
