title: Print a two dimension list with format in Python
body: <p>So I have defined a two dimension list in python using:</p>
  
  <pre><code>column = 3
  row = 2
  Matrix =  [['' for i in range(column)] for j in range(row)]
  </code></pre>
  
  <p>Then I started adding values to it:</p>
  
  <pre><code>Matrix[0][0] += 'A'
  Matrix[1][0] += 'AB'
  Matrix[2][0] += 'ABC'
  Matrix[0][1] += 'X'
  Matrix[1][1] += 'XY'
  Matrix[2][1] += 'XYZ'
  </code></pre>
  
  <p>Then I started printing with hope of some sort of format:</p>
  
  <pre><code>for i in range(0, row, 1):
      for j in range(0, column, 1):
          print(Matrix[i][j] + '\t')
  </code></pre>
  
  <p>I was thinking of get result like</p>
  
  <pre><code>A   AB   ABC
  X   XY   XYZ
  </code></pre>
  
  <p>But actually I got:</p>
  
  <pre><code>A   
  AB  
  ABC     
  X   
  XY  
  XYZ 
  </code></pre>
  
  <p>Just wondering what is wrong with my code...</p>
