Learning Python is fun!

Python + Pyqt 

Apparently, this is a note for myself to memorize something.

• big5中文當成字串比對時，才會正確

# -*- coding: utf8 -*-

 

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

•   Using win's app

import subprocess

 buttonCancel.clicked.connect(eventB)

def eventB():
    appW= subprocess.call(r'C:\Program Files\Autodesk\Maya2013\bin\maya.exe',shell=True )

•  get all the drives in win

import os

dri_all = [ '%s:' % d for d in dri_all if os.path.exists('%s:' % d)]

•  Decryption and Encryption

import win32com.client
def encrypt(key,content): # key,content
    EncryptedData = win32com.client.Dispatch('CAPICOM.EncryptedData')
    EncryptedData.Algorithm.KeyLength = 5
    EncryptedData.Algorithm.Name = 2
    EncryptedData.SetSecret(key)
    EncryptedData.Content = content
    return EncryptedData.Encrypt() def decrypt(key,content): # key,content
    EncryptedData = win32com.client.Dispatch('CAPICOM.EncryptedData')
    EncryptedData.Algorithm.KeyLength = 5
    EncryptedData.Algorithm.Name = 2
    EncryptedData.SetSecret(key)
    EncryptedData.Decrypt(content)
    str = EncryptedData.Content
    return str
s1 = encrypt('lovebread', 'hello world')
s2 = decrypt('lovebread', s1)
print s1,s2
# MGEGCSsGAQQBgjdYA6BUMFIGCisGAQQBgjdYAwGgRDBCAgMCAAECAmYBAgFABAgq
# GpllWj9cswQQh/fnBUZ6ijwKDTH9DLZmBgQYmfaZ3VFyS/lq391oDtjlcRFGnXpx
# lG7o
# hello world

• ComboBox 

using self.comboBox.activated.connect(self.XXX) #self.XXX is the function will be the slot

def XXX(self. idx):  #idx is the singal sended from the comboBox
        print 'singal is:' idx

• QTreeWidget

       For custom Item

itemList = []
for fileName in os.listdir(os.path.expanduser("~/"):filePath = os.path.join(os.path.expanduser("~/"), fileName)
lineCount = sum(1 for line in open(filePath))item = QtGui.QTreeWidgetItem()
item.setData(0, 0, fileName)
item.setData(1, 0, str(lineCount))
itemList.append(item)
