Python - 如何分配条目小部件中的数字以列出和汇总它们？

Question

I have created some entry widgets for user to input points for different teams. I would like to know, how is it possible assign them to particular list and sum those points to print the result... My code below showed what have I tried, but it doesn't work and I receive an error: ValueError: invalid literal for int() with base 10: ''

Also, if I will remove sum functions, numbers does not appear in lists. Can anyone explain me how to solve this problem? My code:

AS Your code is written, it do this: When it runs, it tries to get the values on the Entry objects, but there is nothing, so thats the error, you trying to convert to int a ''. The correct thing to do is this:

There are some things to change, you can see them with comments, you are using a list, so, for use the sum() function you need to .append() the value on the list, and every time that you call the function reset the list with pointsTeam1 = [] Use the self.to keep track of the attribute and get the value on the new function get_values() And for last thing, I made a function to check if the value inserted is a numeric value and convert it to int else return 0, you can raise an Error or show some message

I hope I was helpful
