for index, item in enumerate(sequence): process(index, item)
列表初始化:
multilist = [[0 for col in range(5)] for row in range(3)]
用*初始化,出现的问题:

python内置函数:
int([x[, base]]) #将一个字符转换为int类型,base表示进制 int(‘123‘) int(‘123‘,10)
chr(i) 返回整数i对应的ASCII字符
与之相对应的是ord
一种很棒的先序便利树的方法:
def walk(node): """ iterate tree in pre-order depth-first search order """ yield node for child in node.children: for n in walk(child): yield n

python中__attr,以__开头的属性是private的。外界访问不到。
class A(object): def __init__(self): self.__age=10 a=A() print a.__age Traceback (most recent call last): File "H:\final\code\PyTestService\comz\test\Copy of Copy of Test.py", line 12, in <module> print a.__age AttributeError: ‘A‘ object has no attribute ‘__age‘
