Can you help with this. Please, only use 1 return statement (at the end of the function). Use python.

4. Write and test a recursive function that calculates a base value to a power. Example: 213 is 8. (2 is the base, 3 is the power). It should work with negative and positive bases and powers. The function signature is: def to power (base, power): - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Calculates base-power. Use: ans = to_power (base, power) - - - - - - - - - - - - - - - - - Parameters: base - base to apply power to (float) power - power to apply (int) Returns: ans - base ^ power (float)
