title: How can I set infinity as an element of a matrix in python(numpy)?
body: <p>This is the program</p>
  
  <pre><code>import numpy as n
  m = complex('inf')
  z=n.empty([2,2] , dtype = complex)
  z=n.array(input() , dtype = complex )
  </code></pre>
  
  <p>but in the console when i give 'm' as an input i get the following error massage:
  'NameError: name 'm' is not defined'</p>
