title: for loop in python for log-scale increments
body: <p>I want to know if it is possible to loop over a variable with log-scale increments. More specifically I want to generate values for q from 1E-10 to 1E-2 in log-scale increments as 1E-10, 1E-9, 1E-8, 1E-7,1E-6,1E-5,1E-4,1E-3,1E-2. Can you suggest how I can write a for loop for this? </p>
