Python I'；我试图使用.get（）从复选框中获取一个值，但该值不'；似乎没有改变

基本上，当点击复选框时，我假设InputPriority的值会改变，我可以使用它来附加到上面的数组中，以便在其他地方使用它。但当我点击复选框时，它不会改变。因此，我尝试在由复选框触发的命令中使用另一个变量，但这也不会改变。我不明白为什么不会。任何帮助都将不胜感激。（抱歉，代码有点乱）

要获取信息，您可以使用类似于复选按钮的单选按钮，使用下面的代码，您可以获取所选信息

def AddNewFile():
    global Date
    global DateCreated
    global DateModified
    global Action
    global Project

    global ReportNo

    path=Path.get()
    extracted_data=extract_information(path+'.pdf')
    print(extracted_data)
    if '/CreationDate' in extracted_data:
        use=str(extracted_data['/CreationDate'])
        creationdate=datetime.strptime(use[2:10],"%Y%m%d")
        DateCreated.append(str(creationdate)[0:10])
    if '/ModDate' in extracted_data:
        use=str(extracted_data['/ModDate'])
        moddate=datetime.strptime(use[2:10],"%Y%m%d")
        DateModified.append(str(moddate)[0:10])
    if '/Author' in extracted_data:
        Author.append(extracted_data['/Author'])
    if '/Subject' in extracted_data:
        ReportNo.append(extracted_data['/Subject'])
    today=datetime.today()
    print(Prio)  #I think this is where the problem is
    if Prio==1:
        Priority.append(str(Prio))
    else:
        Priority.append('0')
    Date.append(str(today)[0:10])
    Action.append(CalculateActionRequired(str(today)[0:10],len(Priority)-1))
    Project.append(InputProject.get())
    Tag.append(InputTag.get())
    Completion.append(0)
    Comments.append(comments_split(Com.get()))
    Vessel.append(vess.get())
    total_rows = len(Date)+1
    t=Table(root)
    AddNewFileToFile(Com.get())
    closewindow(AddFileWindow)

#This was my attempt of trying to fix the problem myself using another variable
def add_value_to_Priority():
    global Prio
    global InputPriority
    """if Prio==1: #This part was one attempt
        Prio=0
    else:
        Prio==1"""
    print(InputPriority.get())
    Prio=int(InputPriority.get())#This was another attempt

# this is the function called when the button is clicked, and calls the other subroutines above
def AddFileCmmd():
    global Prio
    global AddFileWindow
    global Path
    global InputPriority
    global InputProject
    global InputTag
    global vess
    global Com
    Prio=0
    AddFileWindow=Tk()
    AddFileWindow.title('Add file')
    AddFileWindow.geometry('500x500')
    Label(AddFileWindow,text='Enter File Name').grid()
    Path=Entry(AddFileWindow)
    Path.grid(sticky=E)
    InputProject=StringVar(AddFileWindow)
    InputProject.set('Input Project')
    w = OptionMenu(AddFileWindow, InputProject, "one", "two", "three")
    w.grid()
    InputTag=StringVar(AddFileWindow)
    InputTag.set('Input Tag')
    z = OptionMenu(AddFileWindow, InputTag, "one", "two", "three")
    z.grid()
    Label(AddFileWindow,text='Enter Vessel').grid()
    vess=Entry(AddFileWindow)
    vess.grid(sticky=E)
    Label(AddFileWindow,text='Enter Comments, seperate by |').grid()
    Com=Entry(AddFileWindow)
    Com.grid(sticky=E)
    InputPriority=IntVar()
# This is the checkbox which is not working
    Checkbutton(AddFileWindow, text='Prioity',variable=InputPriority, onvalue=1, offvalue=0,command=add_value_to_Priority).grid() 
    Button(AddFileWindow,text='Done',command=AddNewFile).grid() #This calls a procedure above
    AddFileWindow.mainloop()

通过使用信息变量，您可以通过“是”表示为“1”，而“否”表示为“0”来判断选择了哪一个

您可以尝试使用复选框来执行此操作，但我不确定它是否工作相同。

您知道您可以使用

global，

将

global

语句组合在一起，您是否可以将代码简化为问题，而不仅仅是转储整个内容。请将代码简化为一个完整的代码。如果问题是如何从复选框中获取值，那么我们只需要复选框、用于获取值的代码以及足够的额外代码就可以了。很可能有多个

Tk（）

实例。

    information = IntVar()
    
    radiobutton_yes = Radiobutton(AddFileWindow, text = "Yes", value = 1,
                                variable = information)
    
    radiobutton_no = Radiobutton(AddFileWindow, text = "No", value = 0,
                                variable = information)
