title: matlab and Python in numeric calculations
body: <p>I am kind of new in Python. I am trying to convert some MATLAB code to Python. This MATLAB code uses a lot of arrays, such as x = [-0.22258   0.50889  -0.35733  -0.22992  -0.26910]. I need to do all kinds of mathematical operations on these arrays, e.g. +/-/* and division. What is the best way to express an array of numbers in Python for this purpose?</p>
  
  <p>Thank you. </p>
