======================遍历列表========================
# 直接遍历list：
for elem in list: pass
# 通过索引获取
for i in range(len(list)): elem = list[i] pass
# 基于enumerate()遍历
for i, elem in enumerate(list): pass
# 基于iter()遍历
listIter = iter(list) while True: try: elem = listIter.next() # .... expect StopIteration, ex: // NOOP
=====================遍历dict==========================
# 通过key遍历
for key in dict.keys(): value = dict.get(key) pass
# 直接遍历，本质是先转换成 (key,value)的list
for key,value in dict.items(): pass
# iteritems() 返回值是 items的迭代器
for key,value in dict.iteritems(): pass
