How to divide two columns element-wise in a pandas dataframe
<p>I have two columns in my pandas dataframe. I'd like to divide column <code>A</code> by column <code>B</code>, value by value, and show it as follows:</p>
<pre><code>import pandas as pd

csv1 = pd.read_csv('auto$0$0.csv')
csv2 = pd.read_csv('auto$0$8.csv')

df1 = pd.DataFrame(csv1, columns=['Column A', 'Column B'])
df2 = pd.DataFrame(csv2, columns=['Column A', 'Column B'])

dfnew = pd.concat([df1, df2])
</code></pre>
<p>The columns:</p>
<pre><code>Column A  Column B
12        2
14        7
16        8
20        5
</code></pre>
<p>And the expected result:</p>
<pre><code>Result
6
2
2
4
</code></pre>
<p>How do I do this?</p>
