to know the attributes of an instance of a class without

Is it not possible with the existing python facilities (without adding
external libraries) ?
To know what a function would do if you were to call it, without
actually calling it, look at the function code with the dis (assembler)
module.
#3.1
>>> import dis
>>> class C:
def __init__(self, a): self.a = a
>>> dis.dis(C.__init__)
2 0 LOAD_FAST 1 (a)
3 LOAD_FAST 0 (self)
6 STORE_ATTR 0 (a)
9 LOAD_CONST 0 (None)
12 RETURN_VALUE
If you read the doc, or know assembler, you would see that the instance
gets attribute a. Use dir(C) to find all the methods to disassemble.
