title: how to use pandas and get csvfile value
body: <p>I have a csv file. test.csv</p>
  <pre><code>1,1,1,1
  </code></pre>
  <p>I want to load this as variables.</p>
  <p>My code:</p>
  <pre><code>import pandas as pd
  ch_file=pd.read_csv(&quot;test.csv&quot;)
  ch1_value=ch_file.columns[0]
  ch2_value=ch_file.columns[1]
  ch3_value=ch_file.columns[2]
  ch4_value=ch_file.columns[3]
  
  print(ch1_value, ch2_value, ch3_value, 
   ch4_value)
  </code></pre>
  <p>Output is <code>1,1.1,1,1.1</code></p>
  <p>Why does it not print <code>1,1,1,1</code>?<br />
  Where is the <code>.1</code> coming from?</p>
