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 sysa = 100b = Truec = 100Ld = 1.1e =""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
