You can't extend with just 6 since it's not iterable. And the second output in your example is wrong. 'abc' gets added as a single element since you passed it in to extend as a list with one element ['abc']: [1, 2, 3, 4, 5, 'abc']. To make your example output correct, change the abc line to: x.extend('abc'). And remove the x.extend(6) or change it to x.extend([6]).

Also "The extend() method takes one argument, a list," is wrong
