我目前正在使用 Tkinter、openpxl 和 selenium。創建一個接受用戶輸入的 GUI，然后使用 selenium 和 openpxl 抓取網站的資訊，然后將它們匯入到檔案中。目前我的 GUI 正在按預期作業。
我計劃用于這個小專案的頭檔案是：
import tkinter as tk
from tkinter import filedialog as fd
from tkinter import ttk
from tkinter.messagebox import showerror, showinfo
from openpyxl import load_workbook
from selenium import webdriver
我的代碼有點復雜和糟糕，因為我只是邊走邊學，并試圖了解高級編程的作業原理。我是一名大三學生，學習電氣工程，而不是 CS 專業。因此，如果能以簡單的方式指出我所做的任何重大禁忌，我們將不勝感激。我不熟悉通常使用的行話。
def file_lookup():
filetypes = (
('All files', '*.*'),
('Application files', '*.exe'),
('Excel files', '*.xlsx')
)
filename = fd.askopenfilename(
title='Insert File',
initialdir='/',
filetypes=filetypes)
if filename != "":
showinfo(
title='Selected File',
message=filename
)
return filename
def selenium(array_product_name, webdriver):
print(array_product_name)
print(webdriver)
web = webdriver
# main website of MTE Corporation
main_page = "https://www.mtecorp.com/click-find/"
driver = webdriver.Chrome(executable_path=web)
# Goes to main page
driver.get(main_page)
# prints page title
print(driver.title)
# to maximize the browser window
driver.minimize_window()
class MainFrame(ttk.Frame):
# Initialization
def __init__(self, container):
super().__init__(container)
# field options
options = {'padx': 5, 'pady': 5}
# file_name
self.filename = str()
# web driver location
self.web_driver = str()
# settings button
self.button = ttk.Button(self, text="Finished Setting", command=self.settings)
self.button.grid(row=9, column=3, sticky=tk.EW, **options)
# excel button
self.exel_button = ttk.Button(self, text='Insert Excel File', command=self.select_excel)
self.exel_button.grid(column=0, row=9, sticky=tk.EW, **options)
# web driver button
self.web_button = ttk.Button(self, text='Select Web driver', command=self.select_webdriver)
self.web_button.grid(column=1, row=9, sticky=tk.EW, **options)
# add padding to the frame and show it
self.grid(padx=10, pady=10, sticky=tk.NSEW)
def settings(self):
self.check_entry
@property
def check_entry(self):
check = True
# Retrieve the of name, date, and MTE Selection
inputs = [self.projectname.get(), self.Date.get(), self.selected_product.get(), self.filename,
self.web_driver]
print(inputs)
if inputs[0] == '':
showerror(
title='Error-Name',
message='Please type in name.'
)
check = False
if inputs[1] == '':
showerror(
title='Error-Date',
message='Please type in Date.'
)
check = False
if inputs[2] == '':
showerror(
title='Error-Selection',
message='User did not Selected Product Line, Please Check.'
)
check = False
if inputs[3] == '':
showerror(
title='Error-Excel File',
message='User did not Inserted an Excel File.'
)
check = False
if inputs[4] == '':
showerror(
title='Error-Webdriver',
message='User did not Inserted a Selenium based Webdriver.'
)
check = False
if check:
showinfo(
title='Success',
message='Settings are successful'
)
self.show_selected_product()
product_name = load_excel(inputs[3])
selenium(product_name, inputs[4])
def select_excel(self):
self.filename = file_lookup()
def select_webdriver(self):
self.web_driver = file_lookup()
目前，我正在解決的錯誤是使用用戶選擇的 selenium webdriver 并打開特定網頁而演變的。將來，我的目標是，每當其他人在他們的計算機上使用此 GUI 時，他們只需選擇他們的 chrome 驅動程式，而不必更改主要代碼和資訊。我有一種感覺，該錯誤是由于用戶輸入的 webdrive 無法訪問 selenium 庫，使其崩潰但又是 idk。
這是錯誤：
Exception in Tkinter callback

uj5u.com熱心網友回復：
我已經完成了你的代碼..... 你犯了一個非常常見的錯誤，你使用 webdriver 作為你的 selenium 函式的引數，但你不能這樣做，因為你已經從 selenium 匯入了 webdriver.....
代碼錯誤：
def selenium(array_product_name, webdriver):
print(array_product_name)
print(webdriver)
web = webdriver
# main website of MTE Corporation
main_page = "https://www.mtecorp.com/click-find/"
driver = webdriver.Chrome(executable_path=web)
回答：
將 webdriver 引數更改為 web...
def selenium(array_product_name, web):
print(array_product_name)
print(web)
# main website of MTE Corporation
main_page = "https://www.mtecorp.com/click-find/"
driver = webdriver.Chrome(executable_path=web)
# Goes to main page
driver.get(main_page)
# prints page title
print(driver.title)
# to maximize the browser window
driver.minimize_window()
更改這部分代碼只需將 webdriver 替換為 web 并擦除 web=webdriver
謝謝
