python - How to center a window on the screen in Tkinter? -

-

I am trying to focus a typewriter window. I know that I can get the window size and the size of the screen in terms of program and I can use it to set that geometry, but I am thinking that an easy way to center the window on the screen is.

You can use the winfo_screenwidth and winfo_screenheight You can try to use, which come back respectively your Tk the width and height of the example (window) and in pixels (in pixels), and with some basic math you can focus your window: 

  TK Diff Center (Toplevel) as imported connector: toplevel.update_idletasks () w = toplevel.winfo_screenwidth () h = toplevel.winfo_screenheight () size = tuple (int (_) toplevel .geometry (for)) Split ('+ ') [0]. Partition ('x') x = w / 2 - size [0] / 2 y = h / 2 - size [1] / 2 toplevel.geometry ("% dx% d +% d +% d"% (size) + (X, y))) If __name__ == '__main__': root = tk.Tk () root.title ("not centered") win = tk.Toplevel (root) win.title ("centered!") (Win) root.mainloop ()

I agree that before returning the values ​​to the width and the height of the window, before I get to the update_idletasks method The call is accurate

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
