python - 在 tkinter 中构建了一个简单的 GUI 提示用户输入值之后，您如何实际使用他们输入的值？

Question

我感谢你的耐心。我是 Python 和 Tkinter 的新手。

我有以下代码提示用户上传文件和赢率百分比。我在另一个文件中编写了一个脚本，该文件使用 pandas 对文件执行一系列操作。问题是我正在努力实际使用用户输入的值，并且目前不确定如何实际运行我在用户值上编写的脚本。我敢肯定这是一个非常简单的解决方案，但对于我的生活，我正在努力解决这个问题。一旦用户输入了他们的值并单击“开始转换”按钮，我将实际运行脚本。您可以提供的任何帮助将不胜感激，谢谢:)

from tkinter import *
from tkinter import messagebox
from tkinter import filedialog

window = Tk()

window.title("Pipeline tool")
window.geometry("250x170")



lbl = Label(window, text="UPLOAD", font=("Arial Bold", 15))
lbl3 = Label(window, text = "Please upload your files into the fields below, than hit convert.", font = ("Arial Bold ", 10))

plbl = Label(window, text="Revenue File", font=("Arial ", 10))
hclbl = Label(window, text="Win Rate Percentage", font=("Arial ", 10))



lbl.grid(column=10, row=0)
lbl3.grid(column=10, row = 10)
plbl.grid(column = 8, row = 20)
hclbl.grid(column = 8, row = 30)
window.geometry('500x500')


txt = Entry(window,width=100)
txt.grid(column=10, row=20)

txt = Entry(window,width=100)
txt.grid(column=10, row=30)
#files = filedialog.askopenfilenames()

def clicked():

    files = filedialog.askopenfilenames()
    messagebox.showinfo('Successful Upload!', 'Your file has been successfully uploaded!')


def clicked1():


    messagebox.showinfo('Please wait', 'Your files are being read. The output should download shortly. !')

btn = Button(window, text="Start Conversion", command= clicked1)
btn.grid(column=10, row=40)

btn = Button(window, text="UPLOAD", command= clicked)
btn.grid(column=13, row=20)

btn = Button(window, text="ENTER", command= clicked)
btn.grid(column=13, row=30)

window.mainloop()

要存储文件路径，请创建一个全局变量（我称之为userFiles）以在用户单击上传时存储文件。要获取赢率输入框中的值，请使用entry.get()。我还为您的代码添加了一些验证，因此用户必须在进行计算之前上传文件并给出胜率。这是代码：

window.title("Pipeline tool")
window.geometry("250x170")

userFiles = None

lbl = Label(window, text="UPLOAD", font=("Arial Bold", 15))
lbl3 = Label(window, text = "Please upload your files into the fields below, than hit convert.", font = ("Arial Bold ", 10))

plbl = Label(window, text="Revenue File", font=("Arial ", 10))
hclbl = Label(window, text="Win Rate Percentage", font=("Arial ", 10))

lbl.grid(column=10, row=0)
lbl3.grid(column=10, row = 10)
plbl.grid(column = 8, row = 20)
hclbl.grid(column = 8, row = 30)
window.geometry('500x500')


fileEntry = Entry(window,width=100)
fileEntry.grid(column=10, row=20)

winEntry = Entry(window,width=100)
winEntry.grid(column=10, row=30)
#files = filedialog.askopenfilenames()

def clicked():
    files = filedialog.askopenfilenames()
    if files:
        global userFiles
        userFiles = files
        messagebox.showinfo('Successful Upload!', 'Your file has been successfully uploaded!')


def clicked1():
    global userFiles
    winRate = winEntry.get()
    if winRate != "" and userFiles != "" and userFiles != None:
        print(winRate, userFiles)
        #Do your calulations here...
        messagebox.showinfo('Please wait', 'Your files are being read. The output should download shortly. !')
    else:
        messagebox.showwarning("Error","Please fill all fields in")

btn = Button(window, text="Start Conversion", command= clicked1)
btn.grid(column=10, row=40)

btn = Button(window, text="UPLOAD", command= clicked)
btn.grid(column=13, row=20)

btn = Button(window, text="ENTER", command= clicked)
btn.grid(column=13, row=30)
