Tkinter中的按鈕錯誤 - 選擇文件，添加它們的路徑

Question

我遇到了Tkinter代碼的問題。代碼的目標是有4個按鈕，2個瀏覽按鈕，用來選擇要相互比較的場景。第三種是爲輸出文件選擇一個目的地。第四個是拉我的python代碼與兩個文件將被計算。

我有我的瀏覽按鈕，在那裏，每當我在窗口中選擇一個文件時遇到困難，他們返回：

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

或

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

的預期結果是所選擇的文件保存它們的路徑，以便我可以在Python代碼中使用這些路徑。

1. 我在網上查找有關pathlabel和infile函數的文檔，並沒有看到任何有用的東西。任何人都可以看到我出錯的地方，爲什麼會出現這些錯誤？

2. 有沒有人有任何關於如何在本地保存路徑的建議（也許是一個變量），以便以後可以將它們拉出來？迄今爲止，我一直沒有成功。

謝謝。

下面是我的代碼：

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，這個代碼可以優化，但這應該讓你去：

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())
