Python Standard Deviation - Efficiency issues with assigning variables

Question

I'm currently working on a program to find standard deviation, z score, etc from some numbers, but my program is extremely inefficient. The way I'm doing it right now by assigning each number its own variable, adding, dividing, assigning that a new variable, so it becomes an infinitely large wall of code. What would be a more efficient way of calculating this than assigning each number its own variable? Also, is there a way to make a list of these numbers based on the number of numbers the user inputs and append these numbers to the list AND THEN do the math?

Answer 1

If you want speed, use numpy . With just using the numpy array things are going to go MUCH faster.

Also scipy has what you want, see this .
