如何在第二个API函数中访问第一个API函数中的变量

def first_api_function():
    variable = "Hello"
    second_api_function(variable)

def second_api_function(variable):
    print(variable)  # 输出：Hello

variable = "Hello"  # 定义全局变量

def first_api_function():
    global variable
    variable = "World"

def second_api_function():
    print(variable)  # 输出：World

def first_api_function():
    variable = "Hello"
    return variable

def second_api_function():
    variable = first_api_function()
    print(variable)  # 输出：Hello
