Python-tkinter,combobox - Passing 2 Parameters Using Lambda Function

Background: A GUI table having a 'skip combobox' widget allowing user to skip current line from executing. Amount of lines in this GUI varies. This 'skip' is created using a for l

Solution 1:

It is very common problem with lambda in loop.

It doesn't copy value from i when you create lambda function but it keeps reference to i. So all functions have reference to the same variable (the same place in memory) and they get value from i when they are exceuted.

You have to assign i to argument in lambda (for example x=i) and use this argument x in your function. This way it will copy current value from i and use in lambda function

lambda event, x=i : self.but_callback(event, x)
