处理“另存为和保存”按钮的功能不起作用

Question

我正在尝试构建一个记事本，但是我的保存和另存为按钮遇到问题，因为TextField中的内容没有保存，文本文档始终返回空，这是我的代码：

def saveFile():
    global infile
    global in_path
    global txt
    try:
        if in_path == '':
    #save as new file
            in_path = asksaveasfile(initialfile='Untitled.txt', defaultextension='txt',filetypes=[("All Files","*.*"),("Text Documents","*txt")])
            if in_path == "":
                in_path = None
            else:
                #try to save file
                with open(in_path, "w") as infile:
                   data = (txt.get(1.0, END))
                   infile.write(data)

                    #change the window title
                root.title(os.path.basename(in_path))
        else:
            #try to save file
            with open(in_path, "w") as infile:
                infile.write(txt.get(1.0, END))
                #change the window title
                root.title(os.path.basename(in_path))
    except:
        pass        
def saveAs():
    global infile
    global in_path
    global txt
    try:
    #save as new file
        in_path = asksaveasfile(initialfile='Untitled.txt', defaultextension='txt',filetypes=[("All Files","*.*"),("Text Documents","*txt")])
        if in_path == " ":
            in_path = None
        else:
                #try to save file
            with open(in_path, "w") as infile:
                infile.write(txt.get(1.0, END))
                #change the window title
            root.title(os.path.basename(in_path))
    except:
            pass

def saveFile（）：全局输入路径全局txt

if in_path == '':
#save as new file
    in_path = asksaveasfilename(initialfile='Untitled.txt', defaultextension='.txt',filetypes=[("All Files","*.*"),("Text Documents","*.txt")])
    if in_path == "":
        in_path = None
    else:
        try:
            #try to save file
            with open(in_path, "w") as infile:
               infile.write(txt.get(1.0, END))


                #change the window title
            root.title(os.path.basename(in_path))
        except:
            pass
else:
        #try to save file
    with open(in_path, "w") as infile:
        infile.write(txt.get(1.0, END))
            #change the window title
            #infile.close()
        root.title(os.path.basename(in_path))

def saveAs（）：全局输入路径全局txt尝试：＃另存为新文件in_path = asksaveasfilename（initialfile ='Untitled.txt'，defaultextension ='。txt'，filetypes = [（“所有文件”，“ 。”），（“文本文档”，“ *。txt”）] ）如果in_path ==“”：in_path =无其他：＃尝试保存文件使用open（in_path，“ w”）作为infile：infile.write（txt.get（1.0，END））＃更改窗口标题root.title（os.path.basename（in_path））除：通过
