title: Loading multiple csv files of a folder into one dataframe
body: <p>i have multiple csv files saved in one folder with the same column layout and want to load it into python as a dataframe in pandas.</p>
  
  <p>The question is really simliar to this <a href="https://stackoverflow.com/questions/38330524/speed-up-the-process-of-import-multiple-csv-into-python-dataframe">thread.</a></p>
  
  <p>I am using the following code:</p>
  
  <pre><code>import glob
  import pandas as pd
  salesdata = pd.DataFrame()
  for f in glob.glob("TransactionData\Promorelevant\*.csv"):
      appenddata = pd.read_csv(f, header=None, sep=";")
      salesdata = salesdata.append(appenddata,ignore_index=True)
  </code></pre>
  
  <p>Is there a better solution for it with another package?</p>
  
  <p>This is taking to much time.</p>
  
  <p>Thanks</p>
