每個循環的字符串的新值

Question

我正在製作一個類似於遊戲的RPG。玩家和敵人輪流戰鬥。 敵方和玩家都有一個傷害範圍[ex（4,10）]，並且攻擊時攻擊範圍內有一個隨機數。

我有這個功能循環，直到其中一個字符達到0 HP。 唯一的問題是它只需要一個隨機數的第一個循環，然後在其餘的循環使用相同的數字。我如何爲每個新循環獲得一個新的隨機數？

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

Answer 1

將dmg = random.randint(dmg_min, dmg_max)在功能fightmode的while循環中，所以，它的重新計算的每個循環，並重新定義函數爲：

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

Answer 2

需要時就產生一個新的隨機數：

而不是：

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

此更改爲：

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

而稍微改變功能：

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.'
