How to get rid of newline char

Sep 19th, 2008

Hi,

Below is my test code, i have a list of names in a file, i read the names and i have to insert them as menu options in the menubar. Since its a dynamic menu and people can add new menu's it has to be read from a file everytime its loaded. Problem is that its appending an extra character after everyname in the menu, something line '[]'(check the attached screen shot) which i assume is the newline char, since i'm inserting that too... How can i get rid of that, any suggestions? i tried reading and writing the file in binary mode but makes no difference.

Use string method strip() to remove newline characters.
