我有一个程序，使用tkinter和openpyxl制作一个excel比较程序。这是我的代码：
import openpyxl, csv
from tkinter import *
from tkinter.filedialog import askopenfilename
from openpyxl.utils import get_column_letter, column_index_from_string
output = open('differences.csv', 'w', newline='')
output_writer = csv.writer(output)

sheet1, sheet2 = '', ''
column_1, column_2 = '', ''
root = Tk()
root.configure(background='light green')
root.geometry("500x500")
root.wm_title("BananaCell")
e1 = Text(root, width=15, height=1)
e1.pack()
e1.place(x=70, y=150)
e2 = Text(root, width=15, height=1)
e2.pack()
e2.place(x=300, y=150)
column1_entry = Text(root, width=5, height=1)
column1_entry.pack()
column1_entry.place(x=135, y=250)
column2_entry = Text(root, width=5, height=1)
column2_entry.pack()
column2_entry.place(x=385, y=250)
def destroy():
root.destroy()
def ask_for_filename_1():
global wb1
wb1 = askopenfilename(title="Select Workbook 1")
print(str(wb1))
return wb1
def ask_for_filename_2():
global wb2
wb2 = askopenfilename(title="Select Workbook 1")
print(str(wb2))
return wb2
def ask_for_sheet1():

mainloop()
程序崩溃并给出以下错误：
No such file or directory ''，我不确定它是否会完全按计划运行。有人能重写我的代码使其顺利编译吗？一切都很好 最佳答案
从您的代码中我可以看到，问题是因为您没有实际地将文件名添加到要使用的变量中。
因此，当程序到达workbook1、workbook2、worksheet1和worksheet2所在的行时，程序将在创建变量openpyxl.load_workbook(str(wb1))、wb1、wb2、wb1和sheet1之前尝试运行命令sheet2。在创建以下内容之前，需要具有要求将文件名分配给要调用的变量的函数：
workbook1 = openpyxl.load_workbook(str(wb1))
workbook2 = openpyxl.load_workbook(str(wb2))
worksheet1 = workbook1.get_sheet_by_name(str(sheet1))
worksheet2 = workbook2.get_sheet_by_name(str(sheet2))
下面是一个例子，说明为了实现这一点，您可能需要做些什么。
这不是最好的方法，甚至不是一个好的方法，但它会很快满足你的需要，并举例说明你的工作手册和工作表需要什么来妥善处理。
def ask_for_filename_1():
global wb1
wb1 = askopenfilename(title="Select Workbook 1")
print(str(wb1))
return wb1
ask_for_filename_1() # add this line
def ask_for_filename_2():
global wb2
wb2 = askopenfilename(title="Select Workbook 1")
print(str(wb2))
return wb2
ask_for_filename_2() # add this line
在使用上述变量之前，您需要执行一个将文件名应用于变量的函数。
请记住，我给出的示例只是为了说明在对变量
workbook1、workbook2、worksheet1和worksheet2执行任何操作之前需要执行的操作。您可能需要检查和更改代码，以便以后不再出现此问题。可能添加此部分：
workbook1 = openpyxl.load_workbook(str(wb1))
workbook2 = openpyxl.load_workbook(str(wb2))
worksheet1 = workbook1.get_sheet_by_name(str(sheet1))
worksheet2 = workbook2.get_sheet_by_name(str(sheet2))
在创建每个
wb1、wb2、wb1、sheet1和sheet2之后调用的函数。
