python - Python Tkinter 如何在 txt 文档中编辑脚本的变量？

Question

我试图弄清楚如何打开一个包含脚本的 txt 文件并编辑if not testfolder.filtertxt 文件中循环内的所有变量。我使用 tkinter 作为 GUI，我有一些输入字段，我想用它们来替换这些变量并在按下名为Add Alert的按钮后保存 txt 文件

我要更新的script.txt ：

from exchangelib import Credentials, Account, UTC_NOW,  EWSTimeZone, EWSDateTime, EWSDate, Q
from collections import defaultdict
from datetime import timedelta, datetime
from kayako import KayakoAPI
from kayako import Department, TicketCount, TicketStatus, TicketPriority, TicketType, TicketNote, TicketAttachment, Ticket




#Kayako RESTAPI forbindelse
API_URL = 'https://hidden.com/api/index.php'
API_KEY = 'hidden'
SECRET_KEY = 'hidden'
api = KayakoAPI(API_URL, API_KEY, SECRET_KEY)


credentials = Credentials('[e-mail]', 'hidden')
a = Account('[e-mail]', credentials=credentials, autodiscover=True)

testfolder = a.public_folders_root / 'Hidden' / '[e-mail]'

since = UTC_NOW() - timedelta(hours=24)

high = api.first(TicketPriority, title="High")
openTicket = api.first(TicketStatus, title="Open")
task = api.first(TicketType, title="Task")
departmentid = 5



if not testfolder.filter(subject__icontains=Subj, datetime_received__gt=since, sender=EmailAdr).exists():
    ticket = api.create(Ticket, tickettypeid=task.id, ticketstatusid=openTicket.id, ticketpriorityid=high.id, departmentid=departmentid, userid="unassigned")
    ticket.subject = TicketSubj
    ticket.fullname = TicketName
    ticket.email = TicketEmail
    ticket.contents = TicketBody
    ticket.add()
    print('Log mangler! Opretter kayako ticket....')
else:
    print('Log er fundet.')

我的 tkinter .py 脚本

from tkinter import *


root = Tk()

Timer = 0
timer1 = int(Timer)
EmailAdr = StringVar()
Subj = StringVar()
TicketSubj = StringVar()
TicketName = StringVar()
TicketEmail = StringVar()
TicketBody = StringVar()

root.geometry("400x250")  

e1 = Entry(root, textvariable=Subj)
e1.grid()
e2 = Entry(root, textvariable=EmailAdr)
e2.grid()
e3 = Entry(root)
e3.grid()
e4 = Entry(root, textvariable=TicketSubj)
e4.grid()
e5 = Entry(root, textvariable=TicketName)
e5.grid()
e6 = Entry(root, textvariable=TicketEmail)
e6.grid()
e7 = Entry(root, textvariable=TicketBody)
e7.grid()

def func1():
    global Subj
    Subj = e1.get()

def func2():
    global EmailAdr
    EmailAdr = e2.get()

def func3():
    global Timer
    Timer = e3.get()

def func4():
    global TicketSubj
    TicketSubj = e4.get()

def func5():
    global TicketName
    TicketName = e5.get()

def func6():
    global TicketEmail
    TicketEmail = e6.get()

def func7():
    global TicketBody
    TicketBody = e7.get()

def demAlle():
    func1()
    func2()
    func3()
    func4()
    func5()
    func6()
    func7()



aButton = Button(root, text="Add Alert", command=demAlle)
aButton.grid()


root.mainloop()

您不需要将条目与变量相关联。如果您只是在没有必要时阅读它们。我还添加了一个带有标签的列，以查看我正在使用的字段。

您可以通过多种方式进行替换，具体取决于“script.txt”的变化方式。我假设它可能会改变并首先找到 if 语句的第一行。

假设 if 语句和以下行将始终保持相同的顺序，我将根据条目替换字段，但前提是在条目中输入了某些内容。

在处理文件时，我首先将其读入行列表，因为这很容易使用。处理后，我用替换编写文件（但名称为“new_script.txt”。我假设您使用 Utf-8 编码，否则将其更改为您的首选编码。

from tkinter import *

root = Tk()
root.geometry("400x250")

Label(root, text='Subj:').grid(row=0, column=0, sticky='w')
Subj_entry = Entry(root)
Subj_entry.grid(row=0, column=1)
Label(root, text='EmailAdr:').grid(row=1, column=0, sticky='w')
EmailAdr_entry = Entry(root)
EmailAdr_entry.grid(row=1, column=1)
Label(root, text='TicketSubj:').grid(row=3, column=0, sticky='w')
TicketSubj_entry = Entry(root)
TicketSubj_entry.grid(row=3, column=1)
Label(root, text='TicketName:').grid(row=4, column=0, sticky='w')
TicketName_entry = Entry(root)
TicketName_entry.grid(row=4, column=1)
Label(root, text='TicketEmail:').grid(row=5, column=0, sticky='w')
TicketEmail_entry = Entry(root)
TicketEmail_entry.grid(row=5, column=1)
Label(root, text='TicketBody:').grid(row=6, column=0, sticky='w')
TicketBody_entry = Entry(root)
TicketBody_entry.grid(row=6, column=1)

def demAlle():
    # Read from Entries
    Subj = Subj_entry.get()
    EmailAdr = EmailAdr_entry.get()
    TicketSubj = TicketSubj_entry.get()
    TicketName = TicketName_entry.get()
    TicketEmail = TicketEmail_entry.get()
    TicketBody = TicketBody_entry.get()
    # Read file into a list of rows which is easy to work with
    with open('script.txt', encoding='utf-8') as script:
        rows = script.readlines()
    # Find the place where you want to alter the code
    for index, row in enumerate(rows):
        if row.startswith('if not testfolder.'):
            break
    # Altering lines; this can be done in many ways...
    if Subj != '':          # Check if field is empty
        rows[index] = rows[index].replace('Subj', Subj)
    if EmailAdr != '':
        rows[index] = rows[index].replace('EmailAdr', EmailAdr)
    if TicketSubj != '':
        rows[index+2] = rows[index+2][:21] + TicketSubj + '\n'
    if TicketName != '':
        rows[index+3] = rows[index+3][:22] + TicketName + '\n'
    if TicketEmail != '':

    if TicketBody != '':
        rows[index+5] = rows[index+5][:22] + TicketBody + '\n'
    # Open file and write the new contents
    with open('new_script.txt', 'w', encoding='utf-8') as script:
        for row in rows:
            script.write(row)

aButton = Button(root, text="Add Alert", command=demAlle)
