Create a conditional expression that evaluates to string "negative" if user_val is less than 0, and "nonnegative" otherwise. Sample output with input: -9 -9 is negative

ASuppose that x and y are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iff at least oneof the variables is False.B.Suppose that x, y, and z are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iffat least two of the three variables (x, y, z) are True.C. Consider the following function headers and type contracts:def aragorn(x: int, y: str, z: float) -> str:def gandalf(x: list) -> list:def elrond(x: list, y: bool) -> bool:If the following code runs without errors, what is a header and type contractfor treebeard?a = aragorn(11, 'good', 2.0)b = treebeard(5, gandalf([1, 2, 3]), a)print(elrond(gandalf([4, 5]), b))Write the header and type contract for treebeard.

3. Write a program if for example, the input: 6 8 2028 prints the date June 8, 2028.

Create a conditional expression that evaluates to string "negative" if user_val is less than 0, and "non-negative" otherwise.Sample output with input: -9-9 is negative Use Python for this, please.
