问题 I have an application written in C# that needs to be converted to Python, since I have recently switched to Linux. It's a simple GUI application to manage unknown words while learning a new language. Nevertheless, I need remove_item() function for which I also need find_word() function.

问题 I found the following code http://www.dotnetcurry.com/showarticle.aspx?ID=146 and implemented it into my app, however it only finds the string once and to continue looking for other instances of the string you have to keep pressing the search button (bit tedious with 100's of matches).
