Python is indeed a good tool

I recently studied Python and thought that his Q & A interface is especially suitable for learning programming. Here are two examples.
1. Quick Sort Algorithm Description
>>> Def qsort (aL ):
... If aL = []: return []
... Else:
... Smaller = [x for x in aL [1:] if x <aL [0] # smaller part than aL [0]
... Bigger = [x for x in aL [1:] if x> = aL [0] # greater (or equal) than aL [0]
... Return qsort (smaller) + [aL [0] + qsort (bigger)
...
>>> Qsort ([3, 4, 5, 1])
[1, 3, 4, 5]
>>> Import random
>>> A = range (0,100)
>>>
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]
>>> Random. shuffle ()
>>>
[69, 77, 17, 97, 21, 1, 44, 20, 82, 46, 59, 63, 4, 47, 38, 25, 48, 84, 72, 2, 52, 10, 31, 3, 58, 43, 9, 96, 95, 27, 0, 71, 40, 12, 76, 8, 14, 79, 53, 80, 28, 15, 91, 22, 65, 68, 86, 18, 32, 85, 55, 36, 92, 74, 50, 11, 83, 81, 7, 57, 90, 54, 87, 24, 29, 37, 61, 35, 56, 60, 88, 75, 30, 16, 13, 39, 26, 70, 93, 49, 51, 23, 41, 98, 66, 99, 89, 5, 34, 6, 94, 64, 67, 62, 78, 73, 19, 33, 42, 45]
>>> Qsort ()
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]

Note: although the algorithm efficiency is not high, the meaning is clear.

2. Imitate the QQ tail "Notepad tail"
The"Hook", You need to downloadPyhookModule
Import win32ui, win32con, pyHook, pythoncom
Def hookhandle (event ):
If event. KeyID = 13: # capture the Enter key (Note: QQ tail captures Ctrl + Enter and click send)
Try:
Pwin = win32ui. FindWindow ('notepad ', None) # Find the Notepad window
Textbox = win32ui. find1_wex (pwin, None, 'edit', None) # Find the editing window
Buf = '0x0' * 1024
Oldlen = textbox. sendmessage (win32con. wm_gettext, Buf) # obtain the original text in the editing window.
Textbox. sendmessage (win32con. wm_settext, Buf [0: oldlen] + '/R/nhttp: // www.csdn.net') # Add a tail.
Except t:
Pass
Hm = pyhook. hookmanager () # hook instantiation
Hm. keydown = hookhandle # specifies the callback function
Hm. hookkeyboard () # hook keyboard
Pythoncom. pumpmessages () # message loop

Of course, the QQ tail will certainly not be written in dynamic languages. I am only here to illustrate that python is indeed a good learning tool, as long as you can think of the principle,
