We've replaced the results of the four list comparisons in snippets [4] through [7] below with ???. What are those four values? In [1]: a = [1, 2, 3]
In [2]: b = [1, 2, 3]
In [3]: c = [1, 2, 3, 4]
In [4]: a == b
Out[4]: ???
In [5]: a == c
Out[5]: ???
In [6]: a < c
Out[6]: ???
In [7]: c >= b
Out[7]: ???

In Python, list comparison first checks the elements from the start. For [4], a and b are equal, so Out[4] is True. For [5], a and c are not equal because c has an extra element, so Out[5] is False. For [6], a is less than c because all elements in a match those in c and c has an extra element, making a < c, so Out[6] is True. For [7], c is greater than or equal to b because it has all elements of b plus an extra one, so Out[7] is True.
