Tkinter中的按钮错误 - 选择文件，添加它们的路径

Question

我遇到了Tkinter代码的问题。代码的目标是有4个按钮，2个浏览按钮，用来选择要相互比较的场景。第三种是为输出文件选择一个目的地。第四个是拉我的python代码与两个文件将被计算。

我有我的浏览按钮，在那里，每当我在窗口中选择一个文件时遇到困难，他们返回：

pathlabel.delete(0, END) 
NameError: name 'pathlabel' is not defined 

或

content = infile.read(filename2) 
TypeError: integer argument expected, got str" 

的预期结果是所选择的文件保存它们的路径，以便我可以在Python代码中使用这些路径。

1. 我在网上查找有关pathlabel和infile函数的文档，并没有看到任何有用的东西。任何人都可以看到我出错的地方，为什么会出现这些错误？

2. 有没有人有任何关于如何在本地保存路径的建议（也许是一个变量），以便以后可以将它们拉出来？迄今为止，我一直没有成功。

谢谢。

下面是我的代码：

import os 
from Tkinter import * 
from tkinter import filedialog 

content = 'apple' 
file_path = 'squarebot' 

#FUNCTIONS 
def browsefunc(): #browse button to search for files 
    filename = filedialog.askopenfilename() 
    infile = open(filename, 'r') 
    content = infile.read() 
    pathadd = os.path.dirname(filename)+filename 

    pathlabel.delete(0, END) 
    pathlabel.insert(0, pathadd) 

    return content 

def browsefunc2(): #browse button to search for files 
    filename2 = filedialog.askopenfilename() 
    infile = open(filename2, 'r') 
    content = infile.read(filename2) 
    pathadd = os.path.dirname(filename2)+filename2 

    pathlabel.delete(0, END) 
    pathlabel.insert(0, pathadd) 

    return content 

def process_file(content): #process reconciliation code 
    print(content) 

def directoryname(): 
    directoryname = filedialog.askdirectory() # pick a folder 


#GUI 

root = Tk() 

root.title('Reconciliation Converter') 
root.geometry("598x150") 

mf = Frame(root) 
mf.pack() 


f1 = Frame(mf, width=600, height=250) #file1 
f1.pack(fill=X) 

f2 = Frame(mf, width=600, height=250) #file2 
f2.pack(fill=X) 

f3 = Frame(mf, width=600, height=250) #destination folder 
f3.pack(fill=X) 

f4 = Frame(mf, width=600, height=250) #reconcile button 
f4.pack() 

file_path = StringVar 


Label(f1,text="Select file 1 (Only txt files)").grid(row=0, column=0, sticky='e') #file1 button 
entry = Entry(f1, width=50, textvariable=file_path) 
entry.grid(row=0,column=1,padx=2,pady=2,sticky='we',columnspan=25) 

Label(f2,text="Select file 2 (Only csv files)").grid(row=0, column=0, sticky='e') #file2 button

注意，这个代码可以优化，但这应该让你去：

import os 
from tkinter import * 
from tkinter import filedialog 

content = 'apple' 
file_path = 'squarebot' 

#FUNCTIONS 
def browsefunc(): #browse button to search for files 
    filename = filedialog.askopenfilename() 
    infile = open(filename, 'r') 
    content = infile.read() 
    pathadd = os.path.dirname(filename)+filename 
    file_path1.set(pathadd) 
    return content 

def browsefunc2(): #browse button to search for files 
    filename2 = filedialog.askopenfilename() 
    infile = open(filename2, 'r') 
    content = infile.read() 
    pathadd = os.path.dirname(filename2)+filename2 
    file_path2.set(pathadd) 
    return content 

def browsefunc3(): #browse button to search for files 
    directory = filedialog.askdirectory(initialdir='.') 
    directoryname.set(directory) 
    return content 

def process_file(content): #process reconciliation code 
    print('------------------------------') 
    print(file_path1.get()) 
    print(file_path2.get()) 
    print(directoryname.get())
