title: How to go through all the numbers between -1 and 1 with numpy.arange()?
body: <p>I am trying to write a code for random walk, and in the direction part, I met this problem. I want the direction to be any degrees, what I do is try to use py.arrange to generate as many numbers as possible between -1 and 1. I want to ask is there any better solutions to go through all the numbers between -1 and 1? Thanks!</p>
  
  <p>Here is my code:</p>
  
  <pre><code>def fill_walk(self):
      while len(self.x_values)&lt;self.num_points:
          x_direction=choice(np.arange(-1,1,0.00001))
          x_distance=(int(1))
          x_step=x_direction*x_distance
  
          y_direction=choice(np.arange(-1,1,0.00001))
          y_distance=(int(1))
          y_step=y_direction*y_distance
  </code></pre>
