本文實例講述了Python中list查詢及所需時間計算操作。分享給大家供大家參考，具體如下：

# -*-coding=utf-8 -*-#! python2#filename: list_query#date: 2018-03-25#author: guoswimport timedef cost_time(fun):  def cost(*args,**kwargs):    stime = time.time()    x = fun(*args,**kwargs)    etime = time.time()    print "function name:",fun.__name__    print "time cost:",etime-stime    return x  return cost@cost_timedef list_query(_list,_val):  low = 0  height = len(i) - 1  mid = (height - low) // 2  for n in xrange(height+1):    if _list[n] == _val:      return n  for n in xrange(mid,height+1):    if _list[n] == _val:      return nif __name__ == "__main__":  i = xrange(100000)  subscript = list_query(i,9999)  print subscript

運行結果：

function name: list_query
time cost: 0.00100016593933
9999
