近几日花了挺多时间在这上面，效果也较为显著，PMangar基本被实现了。期间有一些心得在这儿写下来做记录，顺便也分享：
I’ve been working on Python these days and here are some notes for it:

1. Python中不支持在string.find(str)中使用正则表达式，即str只能是string。
   str in string.find(str) can not be a regular expression, it should be a string.
   Code：

   Python

   a='abcd0123.py' a.find("[w]*.py") a.find("0123.py") #Result: #-1 #4

   1 2 3 4 5 6 7

   a='abcd0123.py' a.find("[w]*.py") a.find("0123.py")   #Result: #-1 #4

2. 使用for i in range(a,b)时，i的值可以等于a到不b-1而不会等于b。同理对于i[a:b]会截取i的第a至b-1个元素。
   In Python, any operation involving a range of a to b means the value can be from a to b-1.
   Code:

   Python

   for i in range(0,2) print i a="0123456789" print a[3:7] #Result: #0 #1 #3456

   1 2 3 4 5 6 7 8 9

   for i in range(0,2) print i a="0123456789" print a[3:7]   #Result: #0 #1 #3456

3. 当已知一个字符的Unicode编码时，例如a=”u4eba”,可以通过unichr()和int()将其转换为相应字符的Unicode形式即b=”u4eba”
   When you know the unicode number of a charactor, you can get the corresponding character by using unichr() and int().
   Code:

   Python

   a=r'u4eba' #a is a string with 6 characters, the last 4 characters represents the unicode number of a chinese character “人”. b=int(a[2:7],16) #Converting string to an decimal integer using base 16 c=unichr(int) #Find the corresponding unicode charactor of the number print a print b print c #Result: #u4eba #20154 #<--This is the decimal number for hex num '4eba' #人

   1 2 3 4 5 6 7 8 9 10 11

   a=r'u4eba' #a is a string with 6 characters, the last 4 characters represents the unicode number of a chinese character “人”. b=int(a[2:7],16) #Converting string to an decimal integer using base 16 c=unichr(int) #Find the corresponding unicode charactor of the number print a print b print c   #Result: #u4eba #20154 #<--This is the decimal number for hex num '4eba' #人
