当我尝试运行此代码时，出现语法错误

Question

当我尝试运行此代码时，出现语法错误，但未说明它是什么行。我不知道我能说些什么..这里是代码，获得误差位：

if "q" in attack: 
     if random.randint(1,100) != range(1,21): 
      print("You hit with a quick attack!") 
      ehp -= 20 
      print("The",enam,"loses 20 damage! It now has",ehp,"health.") 
     else: 
      print("You missed.. :(") 
    elif "p" in attack: 
     if random.randint(1,100) != range(1,51): 
      print("You hit with a power attack!") 
      ehp -= 50 
      print("The",enam,"loses 50 damage! It now has",ehp,"health.") 
     else: 
      print("You missed.. :(") 
    elif "1" in attack: 
     if mana >= skill1[2]: 
      print("You hit with",skill1[0]) 
      ehp -= skill1[1] 
      mana -= skill1[2] 
      print("The",enam,"loses",skill1[1],"damage! It now has",ehp,"health.") 
      print("You now have",mana,"mana.") 
    elif "2" in attack: 
     if mana >= skill2[2]: 
      print("You hit with",skill2[0]) 
      ehp -= skill2[1] 
      mana -= skill2[2] 
      print("The",enam,"loses",skill2[1],"damage! It now has",ehp,"health.") 
      print("You now have",mana,"mana.") 
    elif "3" in attack: 
     if mana >= skill3[2]: 
      print("You hit with",skill3[0]) 
      ehp -= skill3[1] 
      mana -= skill3[2] 
      print("The",enam,"loses",skill3[1],"damage! It now has",ehp,"health.") 
      print("You now have",mana,"mana.") 
    else: 
     print("You typed something wrong.") 

顺便说一句，skill1，skill2和skill3是在比赛中我要作不同的技能所有列表技能1 [0]是技能的名称，技能[1]是技能的攻击力和技能[2]是用来使用技能的法力值。

skill1 = [] 
skill2 = [] 
skill3 = [] 

skill1.append("Very Weak Fireball") 
skill1.append(20) 
skill1.append(30) 
skill2.append("Weak Fireball") 
skill2.append(30) 
skill2.append(40) 
skill3.append("Average Fireball") 
skill3.append(40) 
skill3.append(50) 

Answer 1

不能嵌套的，如果里面的elif：

if "q" in attack: # in line with the elif's 
    if random.randint(1,100) > 21: # cannot compare to range use > 
     print("You hit with a quick attack!") 
     ehp -= 20 
     print("The",enam,"loses 20 damage! It now has",ehp,"health.") 
    else: 
     print("You missed.. :(") 
elif "p" in attack: 
    if random.randint(1,100)> 51: # greater that 51 
     print("You hit with a power attack!") 
     ehp -= 50 
     print("The",enam,"loses 50 damage! It now has",ehp,"health.") 
    else: 
     print("You missed.. :(") 
elif "1" in attack: 

您的代码语法的其余部分都很好，只是改变范围>。

Answer 2

你的代码有太多问题。例如：

if random.randint(1,100) != range(1,21): 

你在这里做什么比较列表（范围的输出，这是[1,2, ..., 20）一个整数（1到100之间的随机数）。你的意思可能是not (... in range(...));这是可以的，但是检查数字是否在两个其他数字之间的时间和内存消耗最多。但是，这不是语法错误。

但是，这里的要点是，你不能正确缩进;您的elif必须具有与相应的if相同的缩进深度。

Answer 3

空闲的输出对我来说：

unindent does not match any outer indentation level

你没有使用正确的压痕。

检查以下：

if "q" in attack: 
    if random.randint(1,100) != range(1,21): 
     print("You hit with a quick attack!") 
     ehp -= 20 
     print("The",enam,"loses 20 damage! It now has",ehp,"health.") 
    else: 
     print("You missed.. :(") 
elif "p" in attack: 
    if random.randint(1,100) != range(1,51): 
     print("You hit with a power attack!") 
     ehp -= 50 
     print("The",enam,"loses 50 damage! It now has",ehp,"health.") 
    else: 
     print("You missed.. :(") 
elif "1" in attack: 
    if mana >= skill1[2]: 
     print("You hit with",skill1[0]) 
     ehp -= skill1[1] 
     mana -= skill1[2] 
     print("The",enam,"loses",skill1[1],"damage! It now has",ehp,"health.") 
     print("You now have",mana,"mana.") 
elif "2" in attack: 
    if mana >= skill2[2]: 
     print("You hit with",skill2[0]) 
     ehp -= skill2[1] 
     mana -= skill2[2] 
     print("The",enam,"loses",skill2[1],"damage! It now has",ehp,"health.") 
     print("You now have",mana,"mana.") 
elif "3" in attack: 
    if mana >= skill3[2]: 
     print("You hit with",skill3[0]) 
     ehp -= skill3[1] 
     mana -= skill3[2] 
     print("The",enam,"loses",skill3[1],"damage! It now has",ehp,"health.") 
     print("You now have",mana,"mana.") 
    else: 
     print("You typed something wrong.") 

后，如果您没有定义攻击，您将收到另一个错误：

NameError: name 'attack' is not defined

如果攻击是一个字符串不是一个变量，您必须将其替换为“攻击”（加引号）

由于@Padraic坎宁安在评论中说，攻击显然是个变数！所以你必须定义它。 :)
