You can use math.pi to calculate the area and the circumference of a circle. When you are doing mathematical calculations with Python and you come across a formula that uses π, it’s a best practice to use the pi value given by the math module instead of hardcoding the value....

For example, plugging in Euler’s formula to the trigonometric form will turn it into the exponential one. You can either call the cmath module’s exp() or raise the e constant to a power to get the same result: Python >>> import cmath >>> algebraic = 3 + 2j >>> geometric =...
