title: Python how to plot graph sine wave
body: <p>I have this signal :</p>
  
  <pre><code>from math import*
  Fs=8000
  f=500
  sample=16
  a=[0]*sample
  for n in range(sample):
      a[n]=sin(2*pi*f*n/Fs)
  </code></pre>
  
  <p>How can I plot a graph (this sine wave)?</p>
  
  <p>and create name of xlabel as 'voltage(V)' and ylabel as 'sample(n)'</p>
  
  <p>What code to do this?</p>
  
  <p>I am so thanksful for help ^<em>_</em>^</p>
