python 基本数据类型占用内存空间大小的实例

python中基本数据类型和其他的语言占用的内存空间大小有很大差别

import sys
a = 100
b = True
c = 100L
d = 1.1
e =""
f = []
g =()
h = {}
i = set([])

print " %s size is %d "%(type(a),sys.getsizeof(a))
print " %s size is %d "%(type(b),sys.getsizeof(b))
print " %s size is %d "%(type(c),sys.getsizeof(c))
print " %s size is %d "%(type(d),sys.getsizeof(d))
print " %s size is %d "%(type(e),sys.getsizeof(e))
print " %s size is %d "%(type(f),sys.getsizeof(f))
print " %s size is %d "%(type(g),sys.getsizeof(g))
print " %s size is %d "%(type(h),sys.getsizeof(h))
print " %s size is %d "%(type(i),sys.getsizeof(i))

 <type 'int'> size is 12 
 <type 'bool'> size is 12 
 <type 'long'> size is 14 
 <type 'float'> size is 16 
 <type 'str'> size is 21 
 <type 'list'> size is 36 
 <type 'tuple'> size is 28 
 <type 'dict'> size is 140 
 <type 'set'> size is 116
