如何修复“类型错误：不能将序列乘以非整数类型的‘浮点数’？

Question

I'm making a Pokemon Battle Simulator (like pokemon showdown in a way) and, during the creation of the battle step (where damage is calculated), an error TypeError: can't multiply sequence by non-int of type 'float' occurs.

Here's my code:

from tkinter import *
from tkinter import ttk


def fight():
    moveused1 = moveset1.get()
    moveused2 = moveset2.get()
    if moveused1 == "Tackle":
        movetype1 = "Normal"
        moverange1 = "Physical"
        power1 = "40"
    if moveused2 == "Tackle":
        movetype2 = "Normal"
        moverange2 = "Physical"
        power2 = "40"
    if moverange1 == "Physical":
       Pokemon1Damage = ((2 * 100 / 5 + 2) * power1 * Attack1 / Defence1 / 50 + 2)
    if moverange1 == "Special":
       Pokemon1Damage = ((2 * 100 / 5 + 2) * power2 * SpAttack2 / SpDefence2 / 50 + 2)

def start():
    global moveset1
    global moveset2
    global HP1
    global Attack1
    global SpAttack1
    global Defence1
    global SpDefence1
    global HP2
    global Attack2
    global SpAttack2 
    global Defence2
    global SpDefence2
    setup.withdraw()
    battle = Tk()
    battle.title(pokemon1 + " VS " + pokemon2)
    battle.geometry("600x400")
    battle.iconbitmap("icon.ico")
    if pokemon1 == "Bulbasaur":
       HP1 = "231"
       Attack1 = "134"
       SpAttack1 = "166"
       Defence1 = "134"
       SpDefence1 = "166"
    if pokemon2 == "Bulbasaur":
       HP2 = "231"
       Attack2 = "134"
       SpAttack2 = "166"
       Defence2 = "134"
       SpDefence2 = "166"
    move1 = move1select.get()
    move2 = move2select.get()
    move3 = move3select.get()
    move4 = move4select.get()
    Label(battle, text="Battle").pack()
    Label(battle, text="").pack()
    Label(battle, text=pokemon1 + "'s Move").pack()
    moveset1 = ttk.Combobox(battle, state="readonly", values=(move1, move2, move3, move4))
    moveset1.current(0)
    moveset1.pack()
    move5 = move5select.get()
    move6 = move6select.get()
    move7 = move7select.get()
    move8 = move8select.get()
    Label(battle, text="").pack()
    Label(battle, text=pokemon2 + "'s Move").pack()
    moveset2 = ttk.Combobox(battle, state="readonly", values=(move5, move6, move7, move8))
    moveset2.current(0)
    moveset2.pack()
    Button(battle, text="Fight", command=fight).pack()

Edit: Here is the full error:

Exception in Tkinter callback

Answer 1

You are multiplying strings and float. Here:

if moverange1 == "Physical":
   Pokemon1Damage = ((2 * 100 / 5 + 2) * power1 * Attack1 / Defence1 / 50 + 2)
if moverange1 == "Special":
   Pokemon1Damage = ((2 * 100 / 5 + 2) * power2 * SpAttack2 / SpDefence2 / 50 + 2)

power1 , power2 , Attack1 , Defence1 , SpAttack2 , SpDefence2 are all strings. You should replace them with integers where you define them in your code.
