如何在python中运行一个函数的变量到另一个函数？

def function1(variable):
    # 执行一些操作
    return variable

def function2(variable):
    # 执行一些操作
    print(variable)

result = function1("Hello")
function2(result)

def function1():
    global variable
    variable = "Hello"

def function2():
    print(variable)

function1()
function2()

def function1():
    variable = "Hello"
    return variable

def function2(variable):
    print(variable)

result = function1()
function2(result)
