如何在Python中将参数从一个函数传递到另一个函数？

def function1(param):
    print(f"function1 received: {param}")

def function2():
    param = "Hello, World!"
    function1(param)

function2()

param = None

def function1():
    global param
    print(f"function1 received: {param}")

def function2():
    global param
    param = "Hello, Global!"

function2()
function1()

def function1():
    return "Hello, Return!"

def function2():
    param = function1()
    print(f"function2 received: {param}")

function2()

class MyClass:
    def __init__(self):
        self.param = None

    def function1(self):
        print(f"function1 received: {self.param}")

    def function2(self):
        self.param = "Hello, Class!"
        self.function1()

obj = MyClass()
obj.function2()

def outer_function(param):
    def inner_function():
        print(f"inner_function received: {param}")
    return inner_function

closure = outer_function("Hello, Closure!")
closure()
