title: read csv file using string from another df(pandas, python, dataframe)
body: <p>is it possible to read csv file using string from another df?</p>
  <p>normally, to read a csv file, i'd use the code as follow:</p>
  <pre><code>df = pd.read_csv(&quot;C:/Users/Desktop/file_name.csv&quot;)
  </code></pre>
  <p>however, i'd like to automate reading a csv file using string from another df:</p>
  <pre><code>df1_string = df1.iloc[0]['file_name']
  df2 = pd.read_csv(&quot;C:/Users/Desktop/df1_string.csv&quot;)
  </code></pre>
  <p>i got a FileNotFoundError when i tried the above code:
  FileNotFoundError: [Errno 2] File b'C:/Users/Desktop/df1_string,csv' does not exist</p>
  <p>kindly advices, many thanks</p>
