程序不断运行-无限循环

Question

我一直在创建组合计算器，这在我创建过程中很困难。 我一直试图解决的问题是处理代码中的无限循环。

oglist = ["a","b","c","d"]
combocounter = 3
lists = {}
comboloop = True
combolist = ["lol"]
pendinglist = ["lol"]
for x in range(0, combocounter):
    lists["list" + str(x)] = ["lol"]
def loop(counter1):
    global recursion1
    global recursion2
    if len(lists["list" + str(counter1)]) == 0:
        lists["list" + str(counter1 - 1)] = lists["list" + str(counter1 - 1)][1:]
        print(lists)
        recursion1 = True
        recursion2 = True
    else:
        lists["list" + str(counter1 + 1)] = lists["list" + str(counter1)][1:]
        print(lists)
        recursion2 = False
    return
def startingloop():
    global recursion1
    if len(lists["list0"]) == 0:
        comboloop = False
    else:
        lists["list1"] = lists["list0"][1:]
        print(lists)
        recursion1 = False
    return
def endingloop():
    global counter2
    global recursion2
    if len(lists["list2"]) == 0:
        lists["list1"] = lists["list1"][1:]
        print(lists)
        recursion2 = True
    else:
        combolist[counter2] = lists["list0"][0]
        for y in range(1, combocounter):
            combolist[counter2] = combolist[counter2] + lists["list" + str(y)][0]
        combolist.append("lol")
        lists["list2"] = lists["list2"][1:]
        counter2 += 1
        print(lists)
        print(combolist)
    return
lists["list0"] = oglist
counter2 = 0
while comboloop == True:
    startingloop()
    while recursion1 == False:
        loop(1)
        while recursion2 == False:
            endingloop()
combolist.remove("lol")
print(combolist)

我放置了一堆打印功能： print(lists)和print(combolist) 。 当我运行它时，列表和组合列表会不断更新和打印。 然后它停止了预期的打印，但是我的程序继续运行。 它也永远不会到达

combolist.remove("lol")
print(combolist)

我努力按照代码的逻辑查找任何问题，但没有找到。 我的代码中不断循环的是什么？

comboloop = False正在创建一个局部变量，该局部变量遮盖了全局变量comboloop。 如果添加

global comboloop

在startingloop（）函数中，程序退出
