如何獲得結構尺寸?我已經使用sys.getsizeof()
,但它沒有給出所需的輸出。混淆結構尺寸
讓我們來看下面的代碼:
#using bit fields for storing variables
from ctypes import *
def MALE():
return 0
def FEMALE():
return 1
def SINGLE():
return 0
def MARRIED():
return 1
def DIVORCED():
return 2
def WIDOWED():
return 3
class employee(Structure):
_fields_= [("gender",c_short, 1), #1 bit size for storage
("mar_stat", c_short, 2), #2 bit size for storage
("hobby",c_short, 3), #3 bit size for storage
("scheme",c_short, 4)] #4 bit size for storage
e=employee()
e.gender=MALE()
e.mar_status=DIVORCED()
e.hobby=5
e.scheme=9
print "Gender=%d\n" % (e.gender)
print "Marital status=%d\n" % (e.mar_status)
import sys
print "Bytes occupied by e=%d\n" % (sys.getsizeof(e))
輸出:
Gender=0
Marital status=2
Bytes occupied by e=80
我想Bytes occupies by e=2
對於任何解決方案?
