Efficient way of adding one character at a time from one string to another in Python -

-

I am currently creating a function using pygame that draws a message on the screen, one letter is each frame ( I.e. red hunting for October ). I know that I can slowly copy (or pass) large slices from the original string, but I know that this will be very resource-intensive. Is there a better way to do this?

Code, gradually using large slices: 

  def full_screen_dialog_tt (thesurface, thefont, theclock, message, thebeep): i = 0 while (i & lt; Len (message): # theclock.tick (60) thesurface.fill ((0, 0, 0)) Start the string display thesurface.blit (thefont.render (message [i] + "_")) Pygame. Display.flip () thebeep.play () while (1): # the entire string is hereclock.tick (60) for event in pygame.events.get (): if event.type == MOUSEBUTTONDOWN: For return < / Code>

In a place where you are deliberately slowing the game (for text fade -i ) - Does it really matter? You can cross the entire string, and change the display routine to display another letter in each frame.

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).
