我正在做一个项目，该项目将允许我模拟打字，以便我可以自动回复电子邮件。为此，我使用Tkinter创建了一个弹出窗口，它总是在所有其他窗口的顶部(总是在前台(，并带有一个按钮。按下按钮后，我有两秒钟的暂停时间，可以点击不同的窗口，然后执行一个引用字符串变量(电子邮件中的文本响应(的Pynput函数。
在我的变量中，我有几个随机选择方法，其中包括一个同义词列表，以改变响应中的单词选择，每次(或大部分时间(都会有所不同。现在，当我运行脚本时，会出现窗口并键入响应，尽管random.choice不是在每次单击按钮时执行，而是在每次关闭Tkinter窗口并再次运行脚本时执行。我希望能够保持Tkinter窗口打开，而不必每次都重新运行脚本才能使random.choice正常工作。如何修改我的脚本，使random.choice在每次单击按钮时都能工作？
这是代码：
from tkinter import *
from pynput.keyboard import Key, Controller
keyboard = Controller()
import time
import random
def center_window(w=300, h=200):
ws = root.winfo_screenwidth()
hs = root.winfo_screenheight()
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
root.geometry('%dx%d+%d+%d' % (w, h, x, y))
rej = random.choice(["Hey", "Hello", "What's up"]) +", thanks for reaching out!
This " + random.choice(["idea", "concept", "project"]) + " was "
+ random.choice(["unique,", "interesting,", "creative,", "solid,", "clever,"]) +
" although it doesn't quite fit our vision right now. "
"We appreciate the submission and look forward to receiving more from you in the future."
root = Tk()
root.title('Automate')
def Reject():
time.sleep(2)
keyboard.type(rej)
RejectButton = Button(root, text="Reject", padx=50, pady=10, command=Reject, fg="#ffffff",
bg="#000000")
RejectButton.pack()
center_window(300, 250)
root.lift()
root.wm_attributes("-topmost", 1)
root.mainloop()
假设random.choice选择"；嘿"quot；概念"；以及"；独特的"；运行脚本后。然后，每次按下按钮直到关闭Tkinter窗口并重新运行脚本后的输出将是：
嘿，谢谢你的联系！这个概念是独一无二的，尽管不太符合我们现在的愿景。我们感谢您的提交并期待着在未来收到更多您的来信。
作为修复缩进之前的解决方案，请尝试在函数Reject():中移动rej
def Reject():
rej = random.choice(["Hey", "Hello", "What's up"]) +", thanks for reaching out!
This " + random.choice(["idea", "concept", "project"]) + " was "
+ random.choice(["unique,", "interesting,", "creative,", "solid,", "clever,"]) +
" although it doesn't quite fit our vision right now. "
"We appreciate the submission and look forward to receiving more from you in the
future."
time.sleep(2)
keyboard.type(rej)
print(rej)
虽然这给了我一个EOL错误，但这和你发布的一样，或者你也可以说：
rej = random.choice(["Hey", "Hello", "What's up"]) +", thanks for reaching out! This " + random.choice(["idea", "concept", "project"]) + " was " + random.choice(["unique,", "interesting,", "creative,", "solid,", "clever,"]) + " although it doesn't quite fit our vision right now. We appreciate the submission and look forward to receiving more from you in the future."
区别是什么，它都在一行中，而你在多行中使用，为此我建议使用三引号和f字符串来动态插入变量，比如：
def Reject():
rej = f'''{random.choice(["Hey", "Hello", "What's up"])}, thanks for reaching out!
This {random.choice(["idea", "concept", "project"])} was {random.choice(["unique,", "interesting,", "creative,", "solid,", "clever,"])} although it doesn't quite fit our vision right now.
We appreciate the submission and look forward to receiving more from you in the future.'''
time.sleep(2)
keyboard.type(rej)
print(rej)
从代码开始到正常代码块结束的所有内容都将只运行一次，而您的rej位于这一点之间，并且将只执行一次，因此这解释了为什么它在整个mainloop()中保持不变，所以为了在每次单击按钮时使其正确随机化，您必须将其移动到函数内部。因此，每次调用该函数都会运行rej，使其成为随机的。
