每个循环的字符串的新值

Question

我正在制作类似 rpg 的游戏。玩家和敌人轮流战斗的地方。 敌人和玩家都有一个伤害范围 [ex (4,10)]，当他们攻击时，它会从这个范围内随机取一个数字。

我有这个函数循环，直到其中一个字符达到 0 HP。 唯一的问题是第一个循环只需要一个随机数，然后在其余循环中使用相同的数字。如何为每个新循环获取一个新的随机数？

   import time
import random
global myhp
myhp = 20
global mydmg
mydmg = random.randint(2,5)
mygold = 0
mystr = 2



def start():
    print "Hello there."
    myname = raw_input("What is your name? ")
    print "Welcome %s, this is..." %myname
    uname = myname.upper()
    print "\t\t\tTHE ADVENTURES OF %s" %uname
    choice0 = ''
    allowed = ["y", "n"]
    while choice0.lower() not in allowed:
        choice0 = raw_input("\nWould you like to play the game? Y/N ")
        choice0 = choice0.lower()
    if choice0 == "y":
        game1()
    if choice0 == "n":
        print "Alright, bye!"

def fightmode(name, hp, dmg, gold):
    global myhp
    print '\n\n\nYou are in a fight with %s' %name
    print '%s has %sHP' %(name, hp)
    while myhp > 0 and hp > 0:
        print '\n\t1. Attack \n\t2. Guard \n\t3. Run away.'
        opt1= ''
        allowed = ["1", "2", "3"]
        while opt1 not in allowed:
            opt1 = raw_input("\nWhat will you do? ")
            if opt1 == "1":
                hp = hp - mydmg
                myhp = myhp - dmg
                print "You have inflicted %d damage on %s. %s's HP is %s" %(mydmg, name, name, hp)
                print "%s attacked you and did %d damage. Your HP fell down to %s" %(name, dmg, myhp)
            if opt1 == "2":
                myhp = myhp + 5
                print "You are now guarding yourself. Your HP is now %d" %myhp
                myhp = myhp - dmg
                print "%s attacked you and did %d damage. Your HP fell down to %s" %(name, dmg, myhp)

    if myhp > 0 :
        print"myhp"
    if hp > 0 :
        print"theirhp"





    def fightmode0():
        print """\n\nThis is your first fight. You have 3 seconds each turn

    start()

Answer 1

将dmg = random.randint(dmg_min, dmg_max)放入函数fightmode的while循环内，这样每个循环都会重新计算，并将函数重新定义为：

def fightmode(name, hp, dmg_min, dmg_max, gold):

Answer 2

只需在需要时生成一个新的随机数：

代替：

fightmode("Scrawny Thug", 15, random.randint(1,5), 4)

将其更改为：

fightmode("Scrawny Thug", 15, (1, 5), 4)

并稍微改变一下功能：

def fightmode(name, hp, dmg_range, gold): # takes range as randint parameters
    global myhp    
    print '\n\n\nYou are in a fight with %s' %name    
    print '%s has %sHP' %(name, hp)    
    while myhp > 0 and hp > 0:   
        dmg = random.randint(*dmg_range) # generate new each time
        print '\n\t1. Attack \n\t2. Guard \n\t3. Run away.'
