Python动态特性

动态特性:
不需要输个数
import inspect
import dis

def howmany():
f=inspect.currentframe()
f=f.f_back
dis.disassemble(f.f_code,f.f_lasti)
n=ord(f.f_code.co_code[f.f_lasti+4])
print n
return range(n)

if __name__=='__main__':
x,y=howmany()
print x,y

>>> import inspect
>>> def howmany():
f=inspect.currentframe().f_back
return range(ord(f.f_code.co_code[f.f_lasti+4]))

>>> x,y=howmany()
>>> x
0
>>> y
1
>>> x,y,z=howmany()
>>> x
0
>>> y
1
>>> z
2
