如何打印多个函数的返回值？

result1 = function1()
print(result1)

result2 = function2()
print(result2)

result3 = function3()
print(result3)

results = (function1(), function2(), function3())
print(results)

results = [function1(), function2(), function3()]
print(results)

result1 = function1()
result2 = function2()
result3 = function3()

output = "Result 1: " + str(result1) + "\n"
output += "Result 2: " + str(result2) + "\n"
output += "Result 3: " + str(result3) + "\n"

print(output)
