python - How to add enumerate or a simple counter inside a message box

Question

I developped a small application, but I would like to know how to add a simple counter inside a message box.

The message box, from QT designer, can appear 3 times. I would like to see the number in the message box.

Let's say it appears the first time, I should see -> 1, a second time, I should see -> 2, a third time -> 3.

Here is the part of the code:

            else:
                second_message_box(QMessageBox.Critical,
                                   "Attention!",
                                   "Il n'est pas possible d'ajouter L'inspecteur " + employeesChosen[i],
                                   QMessageBox.Ok)

I tried this, but it always gives me "1", it never iterate, even when the message box opens more than one time.

else:
    count = 0
    count += 1
    second_message_box(QMessageBox.Critical,
                       str(count),
                       "Il n'est pas possible d'ajouter L'inspecteur " + employeesChosen[i],
                       QMessageBox.Ok)

edit 3:

I did that

count = 0

def foo():
   ...

   else:
    global counter
    count += 1
    second_message_box(QMessageBox.Critical,
                       str(count),
                       "Il n'est pas possible d'ajouter L'inspecteur " + employeesChosen[i],
                       QMessageBox.Ok)

Answer 1

What you can do is create a variable named count and modify that every time that else statement is called.

Here's an example:

def foo():
    count = 0

    for i in range(5):
       count += 1

The += operator increments the variable by the count of the integer on the right. If you happen to place the variable outside any function def blocks, be sure to indicate that the global variable of count needs to be modified.

count = 0

def foo():
   
   for i in range(5):
        global count
        count += 1

You can just print it after a certain line if you need to see it in the console.
