如何将返回值传递给另一个函数

def function1():
    return 10

def function2(value):
    print(value)

result = function1()
function2(result)

def function1():
    return 10

def function2(value):
    print(value)

result = function1()
function2(result)

result = None

def function1():
    global result
    result = 10

def function2():
    global result
    print(result)

function1()
function2()

def function1():
    return 10

def function2(func):
    result = func()
    print(result)

function2(function1)
