为什么我的全局变量不起作用？ （蟒蛇）

Question

我正在为学校制作一款基于文本的游戏，并且希望它具有个性化的名称功能，但是每当我经过定义变量的函数时，其他函数仅使用原始值0 。这是一个示例：

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.')

这是我拥有的确切代码段，当我点击“运行”时，它可以正常工作，直到def prologue（）：我已经排除了它可能是其他东西的可能性，因为在复制器窗口中它说“未定义”名称“名称””

Answer 1

global用于内部函数，该函数指示应被视为局部变量的名称应改为全局名称。

def naming():
    global name

    ...

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

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

此外，您的意思是choice in ["Yes"]，或者更好的是choice == "Yes"

Answer 2

从名称中删除全局，则它应该起作用

Answer 3

这是一个有效的示例，但是将名称传递给序言函数而不是使用全局变量会更好吗？这是另一个主题，但是您必须避免使用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()
