未定义的变量'player_damage' - Python 文本基础游戏

Question

所以这是我在python中的第二个迷你项目，因为我仍在学习，所以我正在使用参考代码并提出问题来制作项目，但是我不断收到错误"未定义的变量'player_damage'"在第49-52行。

Sample_FIGHT = {
player_damage: "You desperately try to stop the %s for %i damage",
enemy_damage: "%s gores you for %i damage",
player_win: "The %s collapses with a thunderous boom",
enemy_win: "You are squished"
}

但我确实在我的函数战斗中定义了变种。

def combat (player, enemy):
player_damage = random.randint (*WEAPONS[player["weapon"]])
enemy_damage = random.randint(*enemy["attack"])
player_win = player_damage > enemy["health"]
enemy_win= enemy_damage  > player["health"]
return player_damage, player_win , enemy_damage, enemy_win

这是整个代码。

import random
#initial question to start
print ("The Adventures Of Magical Nadia")
Answer = input ("Do you wish to embark on this adventures?")
#Question to start game or end game
if Answer == "Yes" or Answer == "yes":
print ("You have accepted the adventure. God Speed my young rass!")
else:
print ("You are a coward and shall not in bark on a great adventure!")
#function for questions avoide repeat 
def ask(question):
answer = input(question + " [y/n]")
return answer in ["y", "Y", "Yes", "YES", "yes"]

#Dic of all the weapons in the game
WEAPONS = {
"Spear": (3, 10), None:(1,3), "knife":(4,16), "Gun":(16,25), "Glass Bottle":(4,16)
}
#Tracking weapon and player health
player = {"weapon":None, "health": (100)}
#to give the player weapons code
player["weapon"] = "Spear"

#Enemys type
enemy = {"name":None, "health":None, "attack":None }
Gaint_spider = {"health":(45), "attack":(7, 10) } 
Dogs = {"health": (50), "attack":(4,15)}
Dragon = {"health": (150), "attack":(35,45)}
#Function each fight gives random dmg, have a player and enemy, winner and loser
def combat (player, enemy):
player_damage = random.randint (*WEAPONS[player["weapon"]])
enemy_damage = random.randint(*enemy["attack"])
player_win = player_damage > enemy["health"]
enemy_win= enemy_damage  > player["health"]
return player_damage, player_win , enemy_damage, enemy_win
#Structure of a fight 
Sample_FIGHT = {
player_damage: "You desperately try to stop the %s for %i damage",
enemy_damage: "%s gores you for %i damage",
player_win: "The %s collapses with a thunderous boom",
enemy_win: "You are squished"
}
# describe the fight in a function
def describe_combat(player, enemy, fight_description):
player_damage, player_win , enemy_damage, enemy_win = combat(player, enemy)
print (fight_description["player_damage"] % (enemy["name"], player_damage))
print (fight_description["enemy_damage"] % (enemy["name"], enemy_damage))
if player_win:
print (fight_description["player_win"] % enemy["name"])
return True
if enemy_win:
print (fight_description["player_win"] % enemy["name"])
return False
return None # fight is a draw
fight_result = describe_combat(player, Gaint_spider, Sample_FIGHT)
if fight_result is None:
print ("This is a draw")
elif fight_result: 
print ("You have won the fight")
else:
print ("You lost")

Answer 1

你在这里定义一个字典，所以你需要传递一个应该是字符串的关键变量，比如：

Sample_FIGHT = {
"player_damage": "You desperately try to stop the %s for %i damage",
"enemy_damage": "%s gores you for %i damage",
"player_win": "The %s collapses with a thunderous boom",
"enemy_win": "You are squished"
}

Answer 2

您没有定义任何键变量。 这就是错误的原因。 因此，只需在以下代码之前初始化它们

Sample_FIGHT = {
player_damage: "You desperately try to stop the %s for %i damage",
enemy_damage: "%s gores you for %i damage",
player_win: "The %s collapses with a thunderous boom",
enemy_win: "You are squished"
}
