• Complete the examples in the docstring and then write the body
of the following function:
def same_first_last(L: list) -> bool:
Precondition: len(L) >= 2
Return True if and only if first item of the list is the same as the
last.
>>> same_first_last([3, 4, 2, 8, 3])
True
>>> same_first_last(['apple', 'banana', 'pear'])
>>> same_first_last([4.0, 4.5])
• Complete the examples in the docstring and then write the body
of the following function:
def is_longer(L1: List, L2: list) -> bool:
"Return True if and only if the length of L1 is longer than the
length
of L2.
>>> is_longer([1, 2, 3], [4, 5])
True
>>> is_longer(['abcdef'], ['ab', 'cd', 'ef'])
>>> is_longer(['a', 'b', 'c'], [1, 2, 3]
• Draw a memory model showing the effect of the following
statements:
|values = [0, 1, 2]
|values[1] = values
