如何获取一串数字，并找出数字是否在增加？

def get_numbers():
    numbers = input("请输入一串数字，以空格分隔：")
    numbers = numbers.split()
    numbers = [int(num) for num in numbers]  # 将输入的数字转换为整数类型的列表
    return numbers

def is_increasing(numbers):
    for i in range(1, len(numbers)):
        if numbers[i] <= numbers[i-1]:
            return False
    return True

numbers = get_numbers()
if is_increasing(numbers):
    print("数字在增加")
else:
    print("数字不在增加")
