title: Read all lines of csv file using .read_csv
body: <p>I am trying to read simple <code>csv</code> file using <code>pandas</code> but I can't figure out how to not "lose" the first row.</p>
  
  <p>For example:</p>
  
  <p><code>my_file.csv</code></p>
  
  <p>Looks like this:</p>
  
  <pre><code>45
  34
  77
  </code></pre>
  
  <p>But when I try to to read it:</p>
  
  <pre><code>In [18]: import pandas as pd
  
  In [19]: df = pd.read_csv('my_file.csv', header=False)
  
  In [20]: df
  Out[20]: 
     45
  0  34
  1  77
  
  [2 rows x 1 columns]
  </code></pre>
  
  <p>This is not what I am after, I want to have 3 rows. I want my <code>DataFrame</code> to look exactly like this:</p>
  
  <pre><code>In [26]: my_list = [45,34,77]
  
  In [27]: df = pd.DataFrame(my_list)
  
  In [28]: df
  Out[28]: 
      0
  0  45
  1  34
  2  77
  
  [3 rows x 1 columns]
  </code></pre>
  
  <p>How can I use <code>.read_csv</code> to get the result I am looking for?</p>
