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
