When using the .get() method whatever is in the entry widget will be converted into a string. For example, regardless of the type of input(It can be a number or sentence), the resulting outcome will be a string. If the user types 4 the output will be "4" as in a string. To get an int from an Entry Widget, first, call the .get() method.
What_User_Wrote = Entry.get()
Now we convert that string into an int like so:
Convert_To_Int = int(What_User_Wrote)
Likewise, if you want to save time you can simply do:
Convert_To_Int = int(Entry.get())
You can use the above method if you don't want to convert str to int.
