The expression uses Python list slicing syntax. Given my_list = [42, 'Life, the Universe, and Everything', 'A duck', 3.14159], the slice my_list[:2] means: take elements from the start of the list up to, but not including, index 2.

Index 0 contains 42, and index 1 contains 'Life, the Universe, and Everything'. Therefore, the slice includes these two elements and stops before index 2.

As a result, the value of my_list[:2] is the sublist containing the first two elements: [42, 'Life, the Universe, and Everything'].

Note on notation: Python represents strings with quotes and lists with square brackets, exactly as shown in the expression and the resulting value.
