Python：推导式关于列表和元组的区别案例

def num1():
    return [lambda x:x+i for i in range(3)]  # 生成函数，并且函数已经执行，循环已经结束,i=2
print(num1())  # [<function num1.<locals>.<listcomp>.<lambda> at 0x000001A6AA9729D0>, <function num1.<locals>.<listcomp>.<lambda> at 0x000001A6AA972A60>, <function num1.<locals>.<listcomp>.<lambda> at 0x000001A6AA972AF0>]
result1 = [m(3) for m in num1()]
print(result1) # [5,5,5]

def num2():
    return (lambda x:x+i for i in range(3))  # 生成生成器，函数未执行，未开始循环
print(num2())  # <generator object num2.<locals>.<genexpr> at 0x000001A6AA939C80>
result2 = [m(3) for m in num2()]
print(result2) # [3, 4, 5]
