导读：div class="cnblogs_code" l = [1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31 find(l,aim,start = 0,end = = len(l) end None end mid_index = ( end - start )//2 + start start l[mid_index] find(l,start = mid_index+1,end = l[mid_index]> find(l,start

l = [1,3,5,7,9,11,13,15,17,19,21,23,25,27,29,31 find(l,aim,start = 0,end == len(l)  end  None  end    
    mid_index = ( end - start )//2 + start  
     start <=end:                         
         l[mid_index]< find(l,start = mid_index+1,end = l[mid_index]> find(l,start = start,end = mid_index - 1 

ret = find(l,27
