今天小编就为大家分享一篇python中in在list和dict中查找效率的对比分析，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

首先给一个简单的例子，测测list和dict查找的时间： import time query_lst = [-60000,-6000,-600,-60,-6,0,6,60,600,6000,60000] lst = [] dic = {} for i in range(100000000): lst.append(i) dic[i] = 1 start = time.time() for v in query_lst: if v in lst: continue end1 = tim
