【问题描述】：

这是我目前用python编写的代码的一小部分，系统在 else 块中打印的“p”处给我一个无效的语法错误。

def bookticket():
        enteredname=name.get()
        enteredage=age.get()
        enteredgender=selectedgender.get()
        enteredtime=selectedtime.get()
        enteredfrom=selectedfrom.get()
        enteredto=selectedto.get()
        enteredemail=email.get()
        if (enteredname=="") or (enteredage=="") or (enteredemail==""):
            messagebox.showerror("ERROR","YOU SEEMED TO HAVE MISSED SOME DETAIL")
        else:
            entereddate=str(selecteddateday.get())+" "+selecteddatemonth.get()+"
"+selecteddateyear.get()
            ticketno=random.randrange(10000,99999)
            ticketnolabel=Label(book,text="YOUR TICKET NUMBER IS:\n"+str(ticketno),font=allfont).grid(row=5,column=6,columnspan=3)
            pleasenotelabel=Label(book,text="PLEASE MAKE NOTE OF TICKET
NUMBER",font=allfont).grid(row=6,column=6,columnspan=5)
            ticketcommand=("insert into details values ('"+enteredname+"','"+enteredage+"','"+enteredgender+"','"+enteredfrom+"','"+enteredto+"','"+entereddate+"','"+enteredtime+"','"+ticketprice+"','"+str(ticketno)+"','"+str(enteredemail+"');")
        
            print(ticketcommand)
            cursor.execute(ticketcommand)
            con.commit()

【解决方案1】：

上一行中缺少str(enteredemail) 的结束)。

ticketcommand=("insert into details values ('"+enteredname+"','"+enteredage+"','"+enteredgender+"','"+enteredfrom+"','"+enteredto+"','"+entereddate+"','"+enteredtime+"','"+ticketprice+"','"+str(ticketno)+"','"+str(enteredemail)+"');")
