while loop completion (Python) [duplicate]

• How do I test one variable against multiple values? 12 answers

I have a while loop that isn't functioning correctly, but I can't work out why. When I run the code, only 'while' is supposed to carry out multiplication on 'overallPrice', but 'else' also does it, making the whole loop useless. The loop also repeats endlessly and I don't know how to stop it.

e.g. If 'numberOfRooms' = 2 and 'paperRemove' = Y or y, price correctly displays at £140. However, if 'numberOfRooms' = 2 and 'paperRemove' = N or n, the price still displays as £140, although it is meant to be £0. The latter result makes the whole loop useless to me.

Here is the section of code. Please note, everything is indented once extra because everything is within a function. Also, 'overallPrice' is set to 0 at the beginning of the code, but is not included here.

#Asking if wallpaper needs to be removed. 

    print ("\nDoes the customer's original wallpaper need to be removed?")
    paperRemove = input ("\nPlease type Y for yes, or N for no: ")

#If paper does need removing, adds £70 to 'overallPrice' multiplied by 'numberOfRooms' if paper does not need
#removing, 'overallPrice' remains at 0?

    while paperRemove == "Y" or "y":
        overallPrice = overallPrice + 70 * numberOfRooms
        print ("The overall Price (Exc VAT.) is currently £",overallPrice)
    else:
        overallPrice = overallPrice + 0
        print ("The overall Price (Exc VAT.) is currently £",overallPrice)


#Next code beneath this.
