东莞找公司网站,淘宝联盟推广做网站违法,南苑网站建设,网络营销理论基础我有一个大字典#xff0c;我必须从中寻找价值观很多次。我的键是整数#xff0c;但代表标签#xff0c;所以不需要添加#xff0c;减法等…我最终尝试评估字符串键和整数键字典之间的访问时间#xff0c;这里是结果。from timeit import TimerDint dict()Dstr dict()fo…我有一个大字典我必须从中寻找价值观很多次。我的键是整数但代表标签所以不需要添加减法等…我最终尝试评估字符串键和整数键字典之间的访问时间这里是结果。from timeit import TimerDint dict()Dstr dict()for i in range(10000):Dint[i] iDstr[str(i)] iprint string key in Dint,print(Timer(7498 in Dint, from __main__ import Dint).timeit(100000000))print int key in Dint,print(Timer(7498 in Dint, from __main__ import Dint).timeit(100000000))print string key in Dstr,print(Timer(7498 in Dstr, from __main__ import Dstr).timeit(100000000))print int key in Dstr,print(Timer(7498 in Dstr, from __main__ import Dstr).timeit(100000000))每次运行之间产生轻微的变化string key in Dint 4.5552944017int key in Dint 7.14334390267string key in Dstr 6.69923791116int key in Dstr 5.03503126455是否证明使用字符串作为键的字典比使用整数作为键更快访问
