li.extend(["two", "elements"]),len(li) ,li.index("example"),"c" in li--False,
li.remove("z")--只删一个,li.pop()--还返回值，li += ['two'],li = [1, 2] * 3 ，
li = [elem*2 for elem in li]，
anystring.split(delimiter, 1)---第二个参数是分割的次数
---------
(x, y, z) = v

print range.__doc__
"%s=%s" % (k, v)
-------apihelper.py-----------自省---反射？----可以做个自动提示功能-
-------------------------type、str、dir----
type(apihelper) == types.ModuleType
callable(string.punctuation),callable(string.join)
getattr(li, "append")("Moe")
