QFileDialog closes window when called

This if my first time asking a question here so please forgive me for any mistakes. So my problem is when I run my program it works fine. But as soon as I click Search the program closes. I use self.pushButton_5.cicked.connect(run) to call on a function that runs: openfile = QtGui.QFileDialog.getOpenFileName(self) # Filename line f = open(openfile, 'r') # New line data = f.read() and this is what causes my program to close. If I replace this with print('Hello') it works fine. I am using Qt Creator to make the GUI and modifying it using Pycharm. I'm Running PyQt5 on windows 7 using Python 3.5. I'm very new to this (4-5 hours tops) however I have been using python in school for the full year (still very basic but I have an okay understanding). This if for a class project that makes up a large portion of the end of year marks. My full code is below: # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'input.ui' # # Created by: PyQt5 UI code generator 5.6 # # WARNING!
