1. tuple不可变序列
list1 = (1,2,3)
2. list 可变序列,相当于java中ArrayList
list2 = [1,2,3]
3. dict 字典表,相当于java中HashMap
list3 = {1:'A',2:'B',3:'C'}
4. 内建模块contextlib,可做AOP
@contextmanager
def dstFn(name):
print("before<%s>" % name)
yield
print("after<%s>" % name)
with dstFn("test"):
print("hello")
print("world")
输出结果
before<test>
hello
world
after<test>
5. virtualenv 相当于java中的maven插件,用于创建一套项目专属的Python环境.
