Python Write a function called myPi(terms) that will return an approximation of PI. Use the Leibniz approximation (https://en.wikipedia.org/wiki/Leibniz formula for %CF%80). The argument called terms defines the number of terms in the Leibniz formula. Use a for loop for the terms value and use this as the result: result result + (-1.0)**n/(2.0*n+1.0). Return the appropriate result (4 result)
