A developer returns an inner function from an outer function. What does this print, and what keeps the captured variable alive after outer() returns?

Code

def outer(msg):
    def inner():
        return f"Message: {msg}"
    return inner

greet = outer("hello")
farewell = outer("goodbye")

print(greet())
print(farewell())
print(greet is farewell)
print(greet.__closure__[0].cell_contents)

def outer(msg): def inner(): return f"Message: {msg}" return inner greet = outer("hello") farewell = outer("goodbye") print(greet()) print(farewell()) print(greet is farewell) print(greet.__closure__[0].cell_contents)
