python 3.x - tkinter frames not working correctly -


i messing around tkinter module first time , not quite sure why widgets aren't being displayed in correct frame?

"text" , "entry" widgets should displayed @ top of top half of window , "button" , "output" widgets @ top of bottom half of window?

thanks

from tkinter import *  main_window = tk() main_window.title("x squared calculator") main_window.geometry("300x300") mw_frame1 = frame(main_window).pack() mw_frame2 = frame(main_window).pack()  text_widget1 = label(mw_frame1, text="please enter value:").pack(side=top) entry_widget1 = entry(mw_frame1, text="please enter value.").pack(side=top) button_widget1 = button(mw_frame2, text='press calculate!').pack(side=top) output_widget1 = label(mw_frame2, text="this number appear").pack(side=top)  main_window.mainloop()

the problem this:

mw_frame1 = frame(main_window).pack()

this sets mw_frame1 none, because pack() returns none. therefore, when try make other widgets children of widget, become children of root window. because children of root window, being packed in place don't expect.

move calls pack() separate statements:

mw_frame1 = frame(...) mw_frame2 = frame(...) ... mw_frame1.pack(...) mw_frame2.pack(...)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
