title: How to choose randomly between two values?
body: <p>So basically I'm trying to get a piece of code to randomly choose between two values -40 and 40. </p>
  
  <p>To do so, I was thinking of using good old mathematics like - </p>
  
  <p>random_num = ((-1)^value)*40, where value = {1, 2}. </p>
  
  <p>random_num, as the name suggest should be a random number.</p>
  
  <p>Any help ? </p>
  
  <p>I am using python, solution using libraries is acceptable.</p>
