Open all files in a folder starting with a certain letter
<p>I would like to open all excel files in a folder that start with a certain string. For example, let's say that I want all files that start with 'hello'. From the following list:
1)hello1.xls
2)hello2.xls
3)other2.xls
4)hello3.xls
5)other3.xls</p>

<p>I would like to open files 1, 2, 4. I would like to open each file, process it and then open then next file. So the workflow should something like:</p>

<pre><code>  for i in files:
     if string=='hello'
       pd.read_xls(i)
       do things
</code></pre>

<p>Thanks in advance.</p>
