我正在制作一个excel比较程序并将其导出为CSV文件。这是我的代码：
import openpyxl, csv
from tkinter import *
from tkinter.filedialog import askopenfilename
from openpyxl.utils import column_index_from_string
output = open('differences.csv', 'w', newline='')
output_writer = csv.writer(output)
wb1, wb2 = '', ''
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():
global sheet1
sheet1 = e1.get("1.0", "end-1c")
print(sheet1)
return sheet1
def ask_for_sheet2():
global sheet2
sheet2 = e2.get("1.0", "end-1c")
print(sheet2)
return sheet2
def get_col_1():
global column_1
column_1 = column1_entry.get("1.0", "end-1c")
print(column_1)
return column_1
def get_col_2():
global column_2
column_2 = column2_entry.get("1.0", "end-1c")
print(column_2)
return column_2
filename_button1 = Button(root, text="Workbook 1", width=12, height=2, command=ask_for_filename_1)
filename_button1.pack()
filename_button1.place(x=100, y=100)
filename_button2 = Button(root, text="Workbook 2", width=12, height=2, command=ask_for_filename_2)
filename_button2.pack()
filename_button2.place(x=300, y=100)
col_button1 = Button(root, text="Enter", width=5, height=1, command=get_col_1)
col_button1.pack()
col_button1.place(x=185, y=248)
col_button2 = Button(root, text="Enter", width=5, height=1, command=get_col_2)
col_button2.pack()
col_button2.place(x=435, y=248)
sheet_button1 = Button(root, text="Enter", width=6, height=0, command=ask_for_sheet1)
sheet_button1.pack()
sheet_button1.place(x=15, y=147)
sheet_button2 = Button(root, text="Enter", width=6, height=0, command=ask_for_sheet2)
sheet_button2.pack()
sheet_button2.place(x=430, y=147)
label1 = Label(root, text="Sheet 1 column letter: ", bg="light green")
label1.pack()
label1.place(x=10, y=250)
label2 = Label(root, text="Sheet 2 column letter: ", bg = "light green")
label2.pack()
label2.place(x=260, y=250)
def write_csv(col1, col2, worksheet1, worksheet2):
for (col, col_1) in zip(worksheet1.iter_cols(min_col = column_index_from_string(col1), max_col=column_index_from_string(col1)), worksheet2.iter_cols(min_col = column_index_from_string(col2), max_col=column_index_from_string(col2))):
for (cell, cell_1) in zip(col, col_1):
if cell.value != cell_1.value and cell.row == cell_1.row:
output_writer.writerow(['Sheet 1 value: ' + ' ' + str(cell.value) + ' ' + 'is not equal to ' + ' ' + 'Sheet 2 value: ' + ' ' + str(cell_1.value) + ' ' + 'on row ' + ' ' + str(cell.row)])
dButton = Button(root, text="Exit", width=8, height=1, command=destroy)
dButton.pack()
dButton.place(x=100, y=60)
mainloop()
workbook1 = openpyxl.load_workbook(str(wb1))
workbook2 = openpyxl.load_workbook(str(wb2))
global sheet1
sheet1 = e1.get("1.0", "end-1c")
global sheet2
sheet2 = e2.get("1.0", "end-1c")
worksheet1 = workbook1.get_sheet_by_name(str(sheet1))
worksheet2 = workbook2.get_sheet_by_name(str(sheet2))
col1 = column1_entry.get("1.0", "end-1c")
col2 = column2_entry.get("1.0", "end-1c")
write_csv(col1, col2, worksheet1, worksheet2)
但是，当我运行以下代码时，我输入所需的条件并最终出现以下错误：_tkinter.TclError: invalid command name ".71847552"。
当我将mainloop()作为文件的最后一行时，我收到此错误：self.fp = io.open(file, modeDict[mode])
FileNotFoundError: [Errno 2] No such file or directory: ''任何人都可以重写我的代码以便成功编译吗？任何帮助都非常感谢你
答案 0 :(得分：1)
在销毁窗口后，这意味着您的代码将继续mainloop，然后尝试引用已被销毁的包含主文件root及其关联方法get的窗口小部件。如果您在窗口被销毁后尝试执行此操作，则会引发错误。
