python"""WHILE statement@see: https://docs.python.org/3/tutorial/controlflow.html@see: https://docs.python.org/3/reference/compound_stmts.html#the-while-statement The while loop executes as long as the condition remains true. In Python, like in C, any non-zero integer value is true; zero is false. The condition may also be a string or list value, in fact any sequence; anything with a non-zero length is true, empty sequences are false.The test used in the example is a simple comparison. The standard comparison operators are written the same as in C:  (greater than), == (equal to), = (greater than or equal to) and != (not equal to)."""def test_while_statement():"""WHILE statement"""# Let's raise the number to certain power using while loop.number = 2 power = 5 result = 1 while power > 0:result *= number power -= 1# 2^5 = 32 assert result == 32
