title: Create a dataframe from arrays python
body: <p>I'm try to construct a dataframe (I'm using Pandas library)
  from some arrays and one matrix.</p>
  
  <p>in particular, 
  if I have two array like this:</p>
  
  <pre><code>A=[A,B,C]
  B=[D,E,F]
  </code></pre>
  
  <p>And one matrix like this : </p>
  
  <pre><code>1 2 2
  3 3 3
  4 4 4
  </code></pre>
  
  <p>Can i create a dataset like this?</p>
  
  <pre><code>  A B C
  D 1 2 2
  E 3 3 3
  F 4 4 4
  </code></pre>
  
  <p>Maybe is a stupid question, but i m very new with Python and Pandas. </p>
  
  <p>I seen this : </p>
  
  <p><a href="https://pandas.pydata.org/pandas-docs/version/0.23.4/generated/pandas.DataFrame.html" rel="noreferrer">https://pandas.pydata.org/pandas-docs/version/0.23.4/generated/pandas.DataFrame.html</a></p>
  
  <p>but specify only 'colums'.</p>
  
  <p>I should read the matrix row for row and paste in my dataset, but I m think that exist a more easy solution with Pandas.</p>
