Pythonエラー：ValueError：randrange（）の非整数arg 1

Question

私のコードで上記のエラーが発生しています。単なるテキストベースのゲームです。ここで

コードです：

import os 
import sys 
import random 

class Player: 
    def __init__(self, name): 
     self.name = name 
     self.maxhealth = 100

    option = input(" ") 
    start1() 

def dead(): 
    print("You have died!") 
    option = input(" ") 

def store(): 
    pass 

main() 

私は他に、）（DEF実行でエラーが発生します：文を。次のような行：EnemyAttack = random.randint（enemy.attack/2、enemy.attack）

アイデア？私は私の問題について詳しく述べるべきですか？ありがとう:)

Answer 1

EnemyAttack = random.randint(math.floor(enemy.attack/2), enemy.attack)を使用するか、math.ceil()を使用してenemy.attack/2の結果を丸めます。

randrange()は、整数全体を想定しています。 enemy.attack/2の結果が整数ではないため、エラーが発生しています。 enemy.attackが奇数であるときは常に小数点以下桁を持ちます。 1つのオプションは、小数点結果が必要な場合に計算されます の後にの計算されます。例えば

：0.5*randrange(2*(enemy.attack/2), 2*enemy.attack)、
