Вот мой код: 

import sys
from PyQt4.QtCore import *
from PyQt4.QtGui import *

# Define Form as a Class
class Form( QDialog):
# Form Constructor
def __init__(self, parent=None):
    super(Form, self).__init__(parent)
    cryptokey = 50
    self.pbuttonName = QPushButton("Developer's Name")
    self.lineeditName = QLineEdit("")
    self.pbuttonSemester = QPushButton("Current Semester")
    self.lineeditSemester = QLineEdit("")
    self.pbutton0 = QPushButton("Open Input File")
    self.lineedit0 = QLineEdit("Input File Name")
    self.label1 = QLabel("Select a Function")
    self.pbutton1 = QPushButton("Character Count")
    self.lineedit1 = QLineEdit("")
    self.pbutton2 = QPushButton("Line Count")
    self.lineedit2 = QLineEdit("")
    self.pbutton3 = QPushButton("Unique Word Count")
    self.lineedit3 = QLineEdit("")
    self.pbutton4 = QPushButton("Average Characters Per Word")
    self.lineedit4 = QLineEdit("")
    self.pbuttonQuit = QPushButton("Quit")
    layout = QVBoxLayout()
    layout.addWidget(self.pbuttonName)
    layout.addWidget(self.lineeditName)
    layout.addWidget(self.pbuttonSemester)
    layout.addWidget(self.lineeditSemester)       
    layout.addWidget(self.pbutton0)
    layout.addWidget(self.lineedit0)
    layout.addWidget(self.lineedit0)
    layout.addWidget(self.label1)
    layout.addWidget(self.pbutton1)
    layout.addWidget(self.lineedit1)
    layout.addWidget(self.pbutton2)
    layout.addWidget(self.lineedit2)
    layout.addWidget(self.pbutton3)
    layout.addWidget(self.lineedit3)
    layout.addWidget(self.pbutton4)
    layout.addWidget(self.lineedit4)
    layout.addWidget(self.pbuttonQuit)
    self.setLayout(layout)
    ck = cryptokey
    self.lineeditName.setFocus()
    self.connect(self.pbuttonName, SIGNAL("clicked()"),self.buttonNamePressed)
    self.connect(self.pbuttonSemester, SIGNAL("clicked()"),self.buttonSemesterPressed)
    self.connect(self.pbutton0, SIGNAL("clicked()"),self.button0Pressed)
    self.connect(self.pbutton1, SIGNAL("clicked()"),self.button1Pressed)
    self.connect(self.pbutton2, SIGNAL("clicked()"),self.button2Pressed)
    self.connect(self.pbutton3, SIGNAL("clicked()"),self.button3Pressed)
    self.connect(self.pbutton4, SIGNAL("clicked()"),self.button4Pressed)
    self.connect(self.pbuttonQuit, SIGNAL("clicked()"),self.buttonQuitPressed)
    s = chr(ck + 20) + chr(ck) + chr(ck-2) +chr(ck-1)+chr(ck+6)
    self.setWindowTitle(s)
# Form Methods
def buttonNamePressed(self):
    self.lineeditName.setText("My Name is Roger Valladares")
def buttonSemesterPressed(self):
    self.lineeditSemester.setText("Fall 2018")
def button0Pressed(self):
    self.lineedit0.setText("FileOpened="+(name))
def button1Pressed(self):
    self.lineedit1.setText("Characters in this file=" +str(numbercharacters))

def button4Pressed(self):
    self.lineedit4.setText("Average characters per word in this file=" +str(averagecharactersperword))
def buttonQuitPressed(self):
    self.done(1)
    app.quit()
    # End of Form Class Definition 
    #this code below is executed based on the file opened.
    d ={}
    uniquewords=[]
    numberlines=0
    numberwords=0
    numbercharacters=0
    averagecharactersperword=0
    uniqueword=0
    x=raw_input ("Enter Filename:")
    filehandle=open(x,'r')
    try:
      print ("This file has been opened=" + (x))
    except:
      print "File not found"
    with filehandle as file:
    for line in file:
      line= line.lower()
      line= line.strip()
      line= line.strip('.')
      line= line.strip('!')
      line= line.strip('?')
      line= line.replace(',','')
      line= line.replace('-',' ')
      words= line.split()
    for ch in line:
        if ch.isalpha()== True:
            numbercharacters= numbercharacters + 1.0
    numberlines = 1+ numberlines
    numberwords += len(words)
    averagecharactersperword = numbercharacters/numberwords
    for word in words:
        d[word]= d.get(word,0)+ 1
    for word in d:
      if word not in d:
        uniqueword=0
      if word in d:
        uniqueword +=1

    #print "Summary of file:"
    #print ("1. Lines in this file=" + str(numberlines))
    #print ("2. Words in this file=" + str(numberwords))
    #print ("3. Characters in this file=" +str(numbercharacters))
    #print ("4. Average characters per word in this file=" 
    +str(averagecharactersperword))
    #print ("5. Unique words, and their responding ocurrences in file="+ 
    str(uniqueword))

Я новичок в Python.Таким образом, в основном пользователь вводит имя файла, которое он хочет, в поле self.lineedit0 = QLineEdit («Имя входного файла»), и мне нужно получить этот ввод в мой код, чтобы открыть указанный файл.
