我的功能在遇到条件后无法正确执行/完全执行

Question

我正在编写一个注册计划来注册大量学生并将其信息保存在数据库中，但是我的功能没有运行。

这是示例代码；我没有收到任何错误，所以我不确定怎么了。

# imported modules
if __name__ == "__main__":
    # creating instance of window stuff
    def erase(f):
        email.delete(0,"end")

    def erase1(e):
        name.delete(0,"end")

    # Password generator (To be sent on user's email)
    mxchars = string.ascii_letters+string.digits

    for pwd in range(1):
        pw = ''
    for c in range(10):
        pw += random.choice(mxchars)

    def aft():
        rot = tk.Tk()
        rot.title("zZ |Ξηr:book:llado")
        rot.iconbitmap(r"C:\PYTHON\Python310\share\Enrolladoico.ico")

        # Simply set the theme
        rot.tk.call("source", r"C:\PYTHON\Python310\Sun-Valley-ttk-theme-master\sun-valley.tcl")
        rot.tk.call("set_theme", "dark")

        # Set a minsize for the window, and place it in the middle
        rot.update()
        rot.minsize(rot.winfo_width(), rot.winfo_height())
        x_cordinate = int((rot.winfo_screenwidth() / 2) - (rot.winfo_width() / 2))
        y_cordinate = int((rot.winfo_screenheight() / 2) - (rot.winfo_height() / 2))
        rot.geometry("+{}+{}".format(x_cordinate, y_cordinate))

        pane_1 = ttk.Frame(paned, padding=0)
        paned.add(pane_1, weight=0)

        tab_1 = ttk.Frame(notebook)

            tab_1.rowconfigure(index=index, weight=0)
            notebook.add(tab_1, text="The Development of Enrollado")

        # Label
        label = ttk.Label(tab_1,text="‎‎‎‎‎‎‎‎",justify="center",font=("-size", 104, "-weight", "bold"),)
        label.grid(row=0, column=0, pady=10, columnspan=2)

        # BG image
        introu = Image.open(r"C:\PYTHON\Python310\share\form.jpg")
        intr = ImageTk.PhotoImage(introu)
        intro = ttk.Label(tab_1,image=intr)
        intro.place(x=0, y=0)

        fr = ttk.Label(tab_1,text="The goal of this system is to assist admissions staff in enrolling more students.\nThis system was devised in order to make the enrollment process for the\nupcoming school year 2022–2023 more efficient and effective in the most convenient\nway possible.

该部分与上面的代码有关。它执行似乎并未完全执行的函数

    def entries_check():

        mail = email.get()
        fname = name.get()
        
        # import re module
        import re
        
        # Make a regular expression for validating an Email
        
        regex = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b'
        # define a function for validating an email
        
        if(re.fullmatch(regex, email.get()))and 'makatiscience.edu.ph' in email.get():
                # some email stuff
            else:
                aft()
        else:
            email.state(["invalid"])
