有了python，我怎么能在周三而不是周日或周一开始我的周开始？(With python how can I have the start of my weeks start on Wednesday instead of Sunday or Monday?)

 我正在使用gmtime, strftime and datetime. 
 
 为了给出上下文，我正在建立一个随叫随到的时间表，并且允许人们轻松切换人们的通话时间表我写了一个脚本来更改xml文件来完成它。 为了让每个随叫随到的人都更容易，我设置了脚本，以便您可以询问特定日期的周数。 大多数内置功能使用星期日或星期一作为开始日期，这不是我需要的。 
 
 有问题的功能： 
 
 我知道%U在星期天开始，我只需要一个解决方案，以便计算它在星期三开始。 
 
`#option 2
def getWeek():
    print("\n\n")
    date = input("Enter the date you want the week number of (MM DD YYYY): ")
    if(len(date) != 10):
        print("You typed it in wrong. Try it again.")
        getWeek()
    else:
        d = time.strptime(date, "%m %d %Y")
        print(strftime("%U" + 2, d))`

I am using gmtime, strftime and datetime.
 
To give context I am setting up an on call schedule, and to allow people to easily switch people's on call schedules I wrote a script to change the xml file to accomplish that. To make it a bit easier on everyone on call I set the script up so that you can ask what the week number of a specific date is. Most of the built in functionality uses Sunday or Monday as the starting date, and that is not what I need. 
 
The Function in question:
 
I know %U starts on Sunday, I just need a work around so that it will calculate for it to start on wednesday.
 
`#option 2
def getWeek():
    print("\n\n")
    date = input("Enter the date you want the week number of (MM DD YYYY): ")
    if(len(date) != 10):
        print("You typed it in wrong. Try it again.")
        getWeek()
    else:
        d = time.strptime(date, "%m %d %Y")
        print(strftime("%U" + 2, d))`
