Python和.randrange if-else语句设置

Question

我的程序非常复杂，下面我提供一个更简单的版本：

while True:#This first part asks the user if he wants to run in deterministic mode(explained later) If he does then deterministic is given a value of 1, else, it is given a value of two.
    mode= input("Would you like to start the program in deterministic mode?(y/n)")
    for i in mode:
        if i not in ('yYnN'):
            print('Please enter either a \'y\' or an \'n\', Please try again')
            break
    else:
        break

if mode=='y' or mode== 'Y':
    deterministic= 1
elif mode=='n' or mode=='N':
    deterministic= 2

下面是一些使用上述代码的代码。这是一条if-elif语句，其中如果确定性值为==1，则函数将运行；如果为deterministic==2，则运行不同的函数。

        if deterministic==2:#position,time, and energy variables will come from the function updateDisplayAllVar(....)

            position,time,energy=updateDisplayAllVar(selection,position,time,energy)
        elif deterministic==1:#position,time, and energy variables will come from the function deterministic(....)

            position,time,energy=deterministic(selection,position,time,energy)

现在我将向您展示上述代码中的两个函数。我认为问题出在他们身上。第一个函数给出一个随机数，并且每次都可能给出一个不同的随机数。第二个函数使用.seed将随机数限制为每次相同的“随机”数。

def updateDisplayAllVar(选择，位置，时间，能量)：

if selection=='w' or selection =='W':
    energy= energy
    position= position+1
    time=time+1
elif selection=='j' or selection =='J':
    energy= energy-1
    position= position+2
    time=time+1 
elif selection=='r' or selection =='R':
    energy= energy-random.randrange(1,2+1)
    position= position+random.randrange(1,4+1)
    time=time+1
elif selection=='f' or selection =='F':
    energy= energy- random.randrange(3,5+1)
    position= position+random.randrange(3,8+1)
    time=time+1



def deterministicMode(selection,position,time,energy):

    if selection=='w' or selection =='W':
        energy= energy
        position= position+1
        time=time+1
    elif selection=='j' or selection =='J':
        energy= energy-1
        position= position+2
        time=time+1 
    elif selection=='r' or selection =='R':
        random.seed(1)
        energy= energy-random.randrange(1,2+1)
        position= position+random.randrange(1,4+1)
        time=time+1
    elif selection=='f' or selection =='F':
        random.seed(3)
        energy= energy- random.randrange(3,5+1)
        position= position+random.randrange(3,8+1)
        time=time+1

现在我的问题是。有了这段代码，即使我不选择确定性(无随机数)模式，我仍然可以得到非随机的、基于第二个函数的数字。也就是说，尽管上面有两个函数，并且我要求每个函数都根据用户的输入运行……运行的总是deterministicMode(selection,position,time,energy)。有没有人知道怎么解决。如果有任何不清楚的地方，请让我知道，我会修复它。

只需用当前系统时间重新设定RNG的种子，使其再次“随机”即可：

def deterministicMode(selection,position,time,energy):
    random.seed()  # <-- Add this line right here

    if selection=='w' or selection =='W':
        energy= energy
        position= position+1
        time=time+
