我做了一个简单的选择游戏，就像使用Python的Rock，Paper，Scissors一样。问题是，在你获胜并输入胜利者的名字之后，while循环仍然会再次执行。这是无法接受的！我看了看它，然后又看了一遍。据我所知，我似乎无法解决问题。这是一个很好的学习时刻。

答案 0 :(得分：3)
这可能是因为您在
中致电winner()之后
if enemyHP == 0:
file = open("wonMessage.txt", "r")
content = file.read()
print(content)
over = True
winner()
你不会立即break退出循环。
相反，在进行while循环检查（over != True）之前，您仍然会继续处理下面的逻辑：
isHitCalc2 = random.randint(1,10)
if isHitCalc2 > 3:
isHitMe = True
else:
isHitMe = False
print("Your enemy missed!")
if isHitMe == True:
randomHitMe = random.randint(1,100)
randomHitDamageMe = math.ceil(randomHitMe * enemyHitFactor)
yourHP -= randomHitDamageMe
if yourHP < 0:
yourHP = 0
print("The enemy hit you for ", randomHitDamageMe, " damage.", sep='')
print("Your HP: ", yourHP)
if yourHP == 0:
file = open("lostMessage.txt", "r")
content = file.read()
print(content)
over = True
您可以通过添加以下内容来修复此特定情况：
if enemyHP == 0:
file = open("wonMessage.txt", "r")
content = file.read()
print(content)
over = True
winner()
break
答案 1 :(得分：0)
如果在函数内调用函数，一旦完成第二个函数，它将继续执行第一个函数：
>>> import time
>>> def repeat():
... num = 0
... while True:
... num+=1
... print num
... time.sleep(1)
... if num == 10:
... stop()
...
>>> def stop():
... print 'This program has stopped!'
... time.sleep(1)
...
>>> repeat()

^CTraceback (most recent call last):

num到达10后，它会调用stop()，但一旦stop()完成，它就会继续循环。而是在调用函数后添加break或空白return：
>>> import time
>>> def repeat():
... num = 0
... while True:
... num+=1
... print num
... time.sleep(1)
... if num == 10:
... stop()
... break
...
>>> def stop():
... print 'This program has stopped!'
... time.sleep(1)

这基本上会在此代码中的return之后添加winner()：
if enemyHP == 0:
file = open("wonMessage.txt", "r")
content = file.read()
print(content)
over = True
winner()
return
