  您没有调用已定义属性的函数 . 只需通过最后添加 _price_inputs() 代码来调用函数：

  from tkinter import *
  import tkinter.messagebox
  
  
  def message():
      text='''sfjkasjdfkjasdfjsdjfjsdlfjasd
              fjsdkfjksadjfsajdjfl    
              sdfasdjflsjdlfsldjflsjd'''
      tkinter.messagebox.showinfo("showing",text)
  
  
  def _price_inputs():
      win2 = Tk()
      win2.title("Transactions for the project Botique")
      win2.geometry("1600x800+0+0")
      win2.configure(bg="black")
  
  
      framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
      frame1 = Frame(win2,width=1000, height=400,bg="white", relief=SUNKEN).pack(side=RIGHT,fill=Y)
      frame2 = Frame(win2, width=775,height=100,bg="white", relief=FLAT).pack(side=BOTTOM)
      frame3 = Frame(win2,width=600,height=430,bg="gray",relief=FLAT).pack(side=LEFT,fill=X)
  
      #framex == heading
      #frame1 == showing the infos 
      #frame2 == bottom_infos
      #frme3 == adding the buttons and widgets
  
      #==++++===========================title=============================
  
      lbl1 = Label(framex,font=("arial", 30, "bold"),bg="powder blue",fg="green",text="Hello this is the title of the page",bd=10,relief=GROOVE).pack(side=TOP)
  
      btn1 = Button(frame1,font=("arial",20,"bold"),bg="powder blue",fg="white",text="click me").pack()
  
  
      win2.mainloop()
  _price_inputs()

  您无法看到新项目 lbl1 和 btn1 ，因为它们是：

  • 孩子到 win2 ，不是任何帧

  • 被另一帧阻止， frame3

  lbl1 和 btn1 是 win2 的子项，因为将None作为第一个位置参数传递，或者默认情况下，窗口小部件的父项被指定为Tk实例 .

  lbl1 和 btn1 使用父参数实例化为 None ，因为：

  framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
  ...
  frame1 = Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)
  

  线条与以下相同：

  Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE).pack(side=TOP)
  framex = None
  ...
  Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)
  frame1 = None
  

  因为 framex 和 frame3 are the return of the method pack which is always None .

  可以通过将几何管理器行与窗口小部件实例化行分开来解决此问题：

  framex = Frame(win2,width=1600,bg="RoyalBlue4",height=100,relief=GROOVE)
  framex.pack(side=TOP)
  ...
  frame1 = Frame(win2,width=600,height=430,bg="red",relief=FLAT)
  frame1.pack(side=LEFT,fill=X)

  注释掉frame3行，看看 lbl1 和 btn1 确实存在：

  #frame3 = Frame(win2,width=600,height=430,bg="red",relief=FLAT).pack(side=LEFT,fill=X)
