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))
