python通用的列表解析结构
通用的列表解析结构如下：for target1 in iterable2
for target1 in iterable3
for target1 in iterable4
... .... ... .... ... ... ... ... ... ... ... ... ... ... .
for targetN in iterableN ]
例如：
rs = ]
print rs
#output:
等价于：
rx = []
for x in range(7):
if x % 2 == 0:
for y in range(-10, 5):
if (y + 1) % 3 == 1:
for z in :
rx.append(x + y + z)
print rx
测试相等性：
print rs == rx #True
