Can Someone Explain This Statement? Lpadded = Win // 2 * [-1] + L + Win // 2 * [-1]

Given that l is a list of integers and win is an integer, the following code produces a list lpadded: lpadded = win // 2 * [-1] + l + win // 2 * [-1] In lpadded -1 is padded to th

Solution 1:

In Python, you can “multiply” a list by an integer to build a list of repeated elements.

>>> [42] * 4[42, 42, 42, 42]
>>> ['hello', 'world'] * 3['hello', 'world', 'hello', 'world', 'hello', 'world']

So the expression win // 2 * [-1] creates a list object containing win // 2 copies of the number -1.
