今天小编就为大家分享一篇python 基本数据类型占用内存空间大小的实例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

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
