How to type a list values literately in same web form.

I need to fill a web form using list values.For that, I used the below code.When executing the 4th line system will generate an error.I used Selenium IDE to test the script.

lis1 = ["ABC", "DEF", "GHI"]
for n in range(lis1):
    type(Key.ENTER)
    type(lis1)
    type(Key.ENTER)
    sleep(2)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.ENTER)
    type(Key.TAB)
    type("100")
    sleep(1)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    type("100")
    sleep(1)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    type(Key.TAB)
    sleep(1)
