Need help with python pi approximation function in 3.7 python: This function accepts no input and returns approximate value of pi. Round the number 10 spaces past decimal point. The number is calculated as: pi = 4*(((-1.0)**n)/((2.0 * n) + 1.0)). The program will expand the series until the absolute value of the next term in the series is less than 10^-7; that term will not be included in the sum.
