[Tutor] Splitting a string

[tee chwee liong]

hi all,
 
i have a function which returns a string. for eg: X='101110'. i want to search for 0 and highlight the location. 
i am thinking of defining X as a list. but how can i split 101110 as there are no spaces in between? i'm thinking if i can put it into a list: X=['1','0','1','1','1','0'], then i can use index to point out the locations of the 0. pls advise. 
i'm using Python2.5 and WinXP.
 
thanks
