    '''
    获取斐波那契数列
    斐波那契数列指的是从第3项开始，每一项都等于前两项之和,开始两项是0,1，如：0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233,377,...
    :param n:数列的第几位,默认10位
    :return: sequence 是列表数据
    '''
    sequence = []
    for i in range(n):
        if i < 2:
            sequence.append(i)
        else:
            sum = sequence[i-1] +sequence[i-2]
            sequence.append(sum)
    return sequence

def Prime_number(n=2,m=100):
    '''
    找出[n,m]范围内的质数
    质数:就是只能被1和本身整除的数,1除外,如2,3,5,7,11,13等等
    :param n: 大于1的整数
    :param m: 数据范围值
    :return: 数据在[n,m]的质数列表
    '''
    num = []
    for i in range(n,m):
        flag = True
        for j in range(2,i):
            #/为除数，%为取模
            if i%j == 0:
                flag = False
        #标记为true则为质数
        if flag:
            num.append(i)
    return num

def bubble_sort(data):
    '''
    冒泡排序原理：比较两个相邻的元素，将值大的元素交换到右边,每次都是从头开始进行比较
    :param data: 输入的数据
    :return: 返回排序结果
    '''
    length = len(data)
    for i in range(length):
        for j in range(0,length-i-1):
            if data[j] > data[j+1] :
                data[j],data[j+1] = data[j+1],data[j]
    return data

if __name__ == "__main__":
    print(Fibonacci_sequence(100))
    print(Prime_number(100,300))
    data = [7,6,5,4,3,9,8,2,1]
    print(bubble_sort(data))

输出：
