I'm not sure what you mean - do you want to change it while the program is running? Why can't you just change it in the code before you run the program? my is a list of tuples - you can't change tuples the way they are (they're immutable). The only open would be to loop through and create new tuples.

my=[(0, 1), (0, 2), (0, 3)]

my2 = my #copy my into a new list
my = [] #clear my
for element in my2: #loop through the old elements
    first = element[0]+1  #you can't change the element itself, so we'll get the value and make a new one
    second = element[1]  #it's not necessary to create a new variable for second, but it's clearer
    my.append((first, second)) #add a new tuple made of the old values
