Open a Datafile(csv,xls,xlsx,ods, etc) using "FILEPICKER" python?
<p>I got to know how to open a data file when we know the name and type of the file but how do we code to pick a file with file picker?</p>

<pre><code>import pyexcel as pe  
records = pe.get_records(file_name="your_file.xls")  
for record in records:  
     print("%s is aged at %d" % (record['Name'], record['Age']))
</code></pre>

<p>I got the problem, Now this code runs!</p>

<pre><code>def loadCsv(self):


    self.progressBar.setValue(0)

    tab_table_view = QtGui.QWidget()
    self.Tab.insertTab(0, tab_table_view, self.File_Name)
