编写一个collect_sim函数(nsim,N,D,p=0.5,nmax=10000),它运行run_sim函数nsim times(参数N,D,p),并返回一个numpy数组,该数组的长度为nmax,给出模拟在指定步数下停止的次数。例如,假设nsim为8,连续运行run_sim得到3,4,4,3,6,5,4,4。你可以把它列为“两个3,4个4,1个5,1个6,0 7,0 8…”

def collect_sims(nsim, N, D, p=0.5, nmax=10000):
    run_sim(N=20, D=6, p=0.5, itmax=5000)
    onecount = 0
    twocount = 0
    threecount = 0
    fourcount = 0
    fivecount = 0
    sixcount = 0
    for k in range (n):
        if D == 1:
            onecount += 1
        if D == 2:
            twocount += 1
        if D == 3:
            threecount += 1
        if D == 4:
            fourcount += 1
        if D == 5:
            fivecount += 1
        if D == 6:
            sixcount += 1

return(k)

print(onecount, "1",twocount,"2",threecount,"3",fourcount,"4",fivecount,"5",sixcount,"6")

它说我的6个变量onecount、twocount等没有定义,我如何定义它们?另外,我可以做些什么来修复我的代码?在

我不知道你为什么还k

不管怎样,问题是oncount,twocount。。。etc在不同的打印范围内。可以将print()放入函数中,也可以返回一个包含计数的元组

像这样的人:

def collect_sims(nsim, N, D, p=0.5, nmax=10000):
    run_sim(N=20, D=6, p=0.5, itmax=5000)
    onecount = 0
    twocount = 0
    threecount = 0
    fourcount = 0
    fivecount = 0
    sixcount = 0
for k in range (n):
    if D == 1:
       onecount += 1
    if D == 2:
       twocount += 1
    if D == 3:
       threecount += 1
    if D == 4:
       fourcount += 1
    if D == 5:
       fivecount += 1
    if D == 6:
       sixcount += 1

return(onecount, twocount, threecount, fourcount,fivecount,sixcount)

onecount, twocount, threecount, fourcount,fivecount,sixcount = collect_sims (...)

print(onecount, "1",twocount,"2",threecount,"3",fourcount,"4",fivecount,"5",sixcount,"6")

不同的解决方案

也许这另一个解决方案可以帮助您:

缩进for循环:在您发布的代码中,它回到原始缩进级别(none,对于for语句)。这就结束了函数,循环在主程序中。您的变量尚未定义(因为它们与函数中的变量不同),并且您的返回值是非法的。在

试试这个吧?在

def collect_sims(nsim, N, D, p=0.5, nmax=10000):
    run_sim(N=20, D=6, p=0.5, itmax=5000)
    onecount = 0
    twocount = 0
    threecount = 0
    fourcount = 0
    fivecount = 0
    sixcount = 0
    for k in range (n):
        if D == 1:
            onecount += 1
        if D == 2:
            twocount += 1
        if D == 3:
            threecount += 1
        if D == 4:
            fourcount += 1
        if D == 5:
            fivecount += 1
        if D == 6:
            sixcount += 1

    print(onecount, "1",twocount,"2",threecount,"3",fourcount,"4",fivecount,"5",sixcount,"6")

collect_sims()

我不能测试,因为你没有提供足够的代码。另外,请注意,我只是将print语句留在原处作为调试跟踪。你必须返回一个数组,但你还没有尝试这么做。原始代码返回的值必须是n+1。这对调用程序没有用处。在


进一步帮助

学习使用6个元素的列表来计算计数,而不是使用六个单独的变量。更妙的是,将所有的模卷放入一个列表中,然后简单地使用count函数来确定每一个的数量。在
