为什么我的全局变量不起作用?(Python)

Question

我正在为学校制作一个基于文本的游戏，我希望它具有个性化的名称功能，但每当我通过定义变量的函数时，其他函数都只使用原始值，即0。这里有一个例子：

global name = 0 #this part is at the top of the page, not actually just above the segment
def naming();
print("A long, long time ago, there was a person who was born very ordinary, but would live to become very extraordinary.n")
time.sleep(2)
while True:
name=input("Who are you? Give me your name.n")
choice = input(f'You said your name was {name}, correct?n')
if choice in Yes:
prologue();
else:
return
def prologue():
print(f'Very well, {name}. You were born with a strange gift that nobody could comprehend, at the time. You were born with the Favor of the Gods.')

这正是我所拥有的代码段；运行"；，它一直工作得很好，直到def-prolog((：我已经排除了它是其他东西的可能性，因为在replicator窗口中，它说"未定义的名称"name"；

Answer 1

这是一个工作示例，但将name传递给prologe函数而不是使用全局变量不是更好吗？这是另一个主题，但你必须避免使用global。

import time
name = 0 #this part is at the top of the page, not actually just above the segment
def naming():
global name
print("A long, long time ago, there was a person who was born very ordinary, but would live to become very extraordinary.n")
time.sleep(2)
while True:
name=input("Who are you? Give me your name.n")
choice = input(f'You said your name was {name}, correct?n')
if choice == "Yes":
prologue()
else:
return
def prologue():
global name
print(f'Very well, {name}. You were born with a strange gift that nobody could comprehend, at the time. You were born with the Favor of the Gods.')

if __name__ == '__main__':
naming()

Answer 2

global在函数内部使用，以指示原本被视为局部变量的名称应该是全局的。

def naming():
global name
...
def prologue():
print(f'Very well, {name}. ...')

只要在调用name之前不调用prologue，就不需要在全局范围内初始化name；则CCD_ 5内部的分配就足够了。

另外，你指的是choice in ["Yes"]，或者更好的是，choice == "Yes"

Answer 3

从名称中删除global，那么它应该可以工作
