Python learning-How to make a dictionary orderly

Using the ordereddict in the collections module, the data in the dictionary can be taken out in the order in which it is stored, and the general dictionary holds the data unordered.

Simulates the process of depositing and withdrawing a ordereddict.

From time Import time
From random import Randint
From collections Import Ordereddict

Person=list (' abcdefgh ') #创建一个人员列表 [' A ', ' B ', ' C ', ' D ', ' E ', ' F ', ' G ', ' H ']
Start=time () #创建开始时间
Od=ordereddict () #创建有序集合
For I in range (8): #创建一个循环8次
Input () #每次回车 to store the relevant information in an ordered dictionary of OD
P=person.pop (Randint (0,7-i))
End=time ()
Print (P,i+1,end-start)
od[p]= (I+1,end-start)
Print ('----------')
For x in OD:
Print (X,od[x])
