Tkinter 按钮不出现

Question

I am trying to build a small GUI for my D&D character but my second attack button does not appear.

Tried to make it read as easy as possible. Its my second try on programming, I find the Tkinter really difficult to work with:(

Written in Python 3:

# Tkinter_buildframe #

root = tk.Tk()
frame = tk.Frame(root)
frame.pack( side = TOP )
frame.pack()
root.geometry("300x200")


# This is the charicter stats #
w = Label(root, text="""
charisma modifier = 4
spellcast attack_bonus = 7
""", font="12")
w.pack()


# Quit_button #
button = tk.Button(frame,
                   text="QUIT",
                   fg="red",
                   command=quit)
button.pack(side=tk.BOTTOM)

# Attack1 eldritch_blast_with_hex #

slogan = tk.Button(frame,
                   text="Eldritch Blast with Hex",
                   command=eldritch_blast_with_hex)
slogan.pack(side=tk.LEFT)


root.mainloop()
def popupmsg(msg):
    popup = tk.Tk()
    popup.wm_title("Eldritch Blast with Hex")
    label = ttk.Label(popup, text=msg, font=NORM_FONT)
    label.pack(side="top", fill="x", pady=10)
    B1 = ttk.Button(popup, text="Okay", command = popup.destroy)
    B1.pack()
    popup.mainloop()

# Attack2 eldritch_blast_without_hex#

slogan = tk.Button(frame,
                   text="Eldritch Blast without Hex",
                   command=eldritch_blast_without_hex)
slogan.pack(side=tk.LEFT)


root.mainloop()
def popupmsg(msg):
    popup = tk.Tk()
    popup.wm_title("Eldritch Blast without Hex")
    label = ttk.Label(popup, text=msg, font=NORM_FONT)
    label.pack(side="top", fill="x", pady=10)
    B1 = ttk.Button(popup, text="Okay", command = popup.destroy)
    B1.pack()

Answer 1

You have multiple root.mainloop() in the code, it just pauses the code from continuing the execution of rest of the code. So remove one of the root.mainloop() and place one at the end of the code.
