   return("The price should be a number")
  
 elif not isinstance(discount,(int, float)):
    return("The discount should be a number")

  
 elif price <= 0:
    return "The price should be greater than 0"
 
 elif discount <= 0 or discount > 100:
    return "The discount should be between 0 and 100"
   
 else:
    apply_discount = price - price*discount/100

Welcome to the forum @mkimaeru,

It’s printing None because your function isn’t returning anything if all validation tests pass.

Also, since a return statement stops processing code at the point, you don’t need to use elif statements.

Happy coding
