這可能是一個(gè)新手問(wèn)題，但我在弄清楚如何從函數(shù)中獲取值以用作另一個(gè)函數(shù)的輸入時(shí)遇到問(wèn)題。我還想了解一些有關(guān)代碼組織的技巧。在此示例中，我試圖獲取要在函數(shù) processFile 中使用的 filePath 和 outPut Folder 路徑。謝謝代碼： from tkinter import *from tkinter import ttkfrom tkinter.filedialog import askopenfilenamefrom tkinter.filedialog import askdirectoryimport PyPDF2from PyPDF2 import PdfFileWriter, PdfFileReaderversion = "v0.0.01"root = Tk()def window (main): main.title("File Opener " + version) width = main.winfo_width() main.geometry('500x200')numero = str(1)def OpenFile(): fileName = askopenfilename(initialdir="C:/", filetypes =(("PDF File", "*.pdf"),("All Files","*.*")), title = "Select PDF File", ) labelName = Label(text="File Path: " + fileName) labelName.pack() print(fileName) return fileNamedef outputFolder(): #Bug, label keeps adding paths outPath = askdirectory() labelName2 = Label(text="Output Folder: " + outPath) labelName2.pack() print(outPath) return outPathdef processFile(inFile,outFolder): ''' print(fileName) get input name and output variables print(outPath)'''label = ttk.Label(root, text ="",foreground="black",font=("Helvetica", 16))label.pack()#Button Open-----------button1 = Button (text = "Open File", command = OpenFile)button1.pack()#Button Start---------buttonStart = Button (text = "Start Process", command = processFile)#give as parameter inputFile and linkbuttonStart.place(height=50, width=100)#Button Open-----------button3 = Button (text = "Output Folder", command = outputFolder)button3.pack()#Menu Bar ----------------menu = Menu(root)root.config(menu=menu)file = Menu(menu)file.add_command(label = 'Open', command = OpenFile)file.add_command(label = 'Exit', command = lambda:exit())menu.add_cascade(label = 'File', menu = file)window(root)root.mainloop()

如果您在變量中使用該函數(shù)，則該函數(shù)的返回結(jié)果將存儲(chǔ)在該變量中。
def Function1(x):
return x*2
var1 = Function1(5)
然后 var1 = 10。
但是關(guān)于您的按鈕，您是想從用戶(hù)那里獲取在按下按鈕時(shí)保存的輸入還是希望按鈕發(fā)送一個(gè)設(shè)定值？
