我正在制作一个投票系统并进行设置，以便用户可以立即将所有候选人放入Tkinter Entry中的位置，并用逗号分隔，然后按一个按钮，为那些候选人创建该位置的新投票。 / p>
以下是我认为相关的代码。
# positions drop down
newVoteChoosePositionLabel = Label(admin, text="Choose the position you are voting for", font=("Arial", 12))
newVoteChoosePositionLabel.place(x=265, y=170)
position = StringVar(admin)
position.set("Chief")
newVoteOption = OptionMenu(admin, position, "Chief", "First Lieutenant", "Second Lieutenant", "Third Lieutenant",
"Fourth Lieutenant")
newVoteOption.place(x=355, y=195)
#add candidates
addCandLabel = Label(admin, text="Add candidates below, separate each candidate with a comma then press enter when all candidates have been entered"
, font=("Arial", 11), wraplength=300, anchor=W)
addCandLabel.place(x=255, y=235)
addCandEntry = Entry(admin, width=40)
addCandEntry.place(x=272, y=295)
#new vote
newVoteButton = Button(admin, text="Create Vote", width=15)
newVoteButton.place(x=335, y=325)
def newVote(event):
pos = position.get()
candidates = addCandEntry.get()
formatted = [x.strip() for x in candidates.split(',')]
for x in formatted:
c.execute("INSERT INTO current VALUES(?,?,?)", pos,x,0)
addCandEntry.bind("<Return>", newVote)
newVoteButton.bind("<Button-1>", newVote)
我会把完整的代码放在这篇文章的底部。
我遇到的问题是，每当我点击按钮时，我都会收到错误TypeError: function takes at most 2 arguments (x given)，其中x是for循环运行的次数。
我一直无法弄清楚为什么会发生这种情况，因为for循环应该在每次运行时将三个提供的值插入到sqlite表中，所以我不确定为什么它会导致错误的基础上for loop runs。
以下是我的完整代码。小心它是凌乱的
