python - TypeError: unsupported operand type(s) for +: 'int' and 'str' even after I change the string to an integer -

-

I am getting an error for my program and I look around the site and now it is understood that I have tried to add a string to an integer error, but when I use the int (variablename) command, I get an error while trying to add it.

This is my code that I am working on: 

  value = input ("how many keys in that value is \ n sum:") int (value) SPC () while a == '1': If price.isdigit (): print (value, 'key') spc () yn = input ("Is this correct? \ N (y / n) Answer:") While yn! = 'Y': spc () price = input ("How much is the value in the key \ n sum:") SPC () print (value, 'key') spc () yn = input ("Is this correct? N (y / n) Answer: "SPC () Brake SPC () print (" This is not a valid key amount ") SPC () Price = input (" How much is the value in keys \ n answer: ")

If you are thinking that what is SPC ()

def (spc): print ("")

I get an error after that and there are other parts of the code but none of these errors Does not belong to not so I left him.

Erorr TypeError: +: Unsupported operation type (s) for 'int' and 'str'

Post-text "itemprop =" text ">

means on this line: 

  total = total + value

value method input Left margin () Input () gives a string and since you can not add + string and anite to the python, it will give you an error. Total = Total + Change the value with: 

  total + = int (value)

winforms - C# Form - Property Change -

I have a form that has a property named car A class with many properties. The Properties is being displayed on the current car on the basis of some user actions that are being displayed. So I have to know whether the property has been allocated or set to zero. I'm aware of INotifyPropertyChanged , but in my case I'm not sure that since this change I have changed my car properties car do not want to monitor the property. Any idea how to accomplish this? In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
