python - 用于从 tkinter 中的按钮事件中弹出警报框的异常，无法找出问题的根源
问题描述
所以我的程序使用一行包含 excel 文件的目录，并将它们全部合并为一个。gui 有两个按钮，一个用于选择路径，一个用于保存所需路径。
我创建了一个 gui 类，我基本上试图在事件发生后将 OptionMenu 选择的文本向前传递，但是引发了一个异常并且我正在努力解决，
长话短说：
import os
from tkinter import *
from tkinter import filedialog
from CombineExcelFiles import *
class GUI:
def __init__(self, master):
self.master = master
master.title('מיזוג קבצי אקסל')
master.geometry('220x100')
self.credit = Label(master, text='')
self.credit.pack()
self.variable = StringVar(master)
self.variable.set('חלבי')
self.opt = OptionMenu(master, self.variable, 'חלבי', 'פרווה')
self.opt.pack()
Button(window, text='בחר תיקייה למיזוג', command=upload).pack(side=RIGHT)
Button(window, text='בחר תייקת הורדה', command=save).pack(side=LEFT)
def upload():
global basepath
basepath = filedialog.askdirectory()
def save():
#print(self.variable.get())
try: #This is line 25
basepath
file_list = []
download_path = filedialog.askdirectory()
for entry in os.listdir(basepath):
if os.path.isfile(os.path.join(basepath, entry)):
if entry[len(entry)-5:] == '.xlsx' and len(entry) == 17:
file_list.append(entry)
data = getData(basepath, file_list)
writeToFile(data, file_list, download_path, master.variable.get())
except NameError:
tkinter.messagebox.showerror('ERROR', 'בחר תיקיית מקור')
这是来自 CombineExcelFiles 的 writeToFile：
def writeToFile(data, files,download_path,variable):
file = Workbook()
ws = file.active
center = Alignment(horizontal='center', vertical='center')
br = Border(left=Side(style='thin'),
right=Side(style='thin'),
top=Side(style='thin'),
bottom=Side(style='thin'))
.
.
.
col = 'C'
row = 3
count = 0
for i in data:
temp = files[count]
for j in i[::-1]:
if type(j) == int or type(j) == float:
ws[col + str(row)].value = ('%.2f' %j)
ws[col + str(row)].alignment = center
ws[col + str(row)].border = br
col = chr(ord(col)+1)
ws['J' + str(row)].value = temp[6:8] + '/' + temp[4:6] + '/' + temp[:4]
ws['K' + str(row)].value = temp[8:10] + ':' + temp[10:12]
row +=1
col = 'C'
ws = fitToCell(ws)
temp_date = datetime.now()
file.save(download_path + '/' + 'מעקב ' + variable + str(temp_date.month) + '-' +
str(temp_date.year) + '.xlsx' )
给出的错误是：
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\******\Anaconda3\lib\tkinter\__init__.py", line 1699, in __call__
return self.func(*args)
File "C:/Users/******/CombineExcels/mainProject.py", line 25, in save
print(self.variable.get())
TypeError: writeToFile() missing 1 required positional argument: 'variable'
先感谢您
编辑，我将代码放在一个文件中，以便它可以运行：

这是错误：
runfile('C:/Users/*****/Desktop/תכנות/untitled2.py',
wdir='C:/Users/*****/Desktop/תכנות')
Exception in Tkinter callback
Traceback (most recent call last):

return self.func(*args)

TypeError: writeToFile() missing 1 required positional argument: 'var'
由于某种原因，它不断从另一条路径返回
解决方案
解决了它，将所有方法放在对象中，而事件在 init 中运行。
我也运行了太多次程序，所以错误与我的代码无关......
