title: How can I fix this 5-line python code?
body: <p>This code is running good on my local computer, but it gives error message on this online platform. The link is here: <a href="https://repl.it/GXl0/1" rel="nofollow noreferrer">https://repl.it/GXl0/1</a></p>
  
  <p>The code:</p>
  
  <pre><code>import numpy as np
  import matplotlib.pyplot as plt
  
  x = np.arange(0, 5, 0.1);
  y = np.sin(x)
  plt.plot(x, y)
  </code></pre>
