九九乘法表

def print_99_mutiply_table():
    for i in range(1,10):
        for j in range(1,i+1):
            print('{} X {} = {}'.format(j,i,i*j),end='   ')#end参数表每行答应完毕，用空格结尾
        print('\n')

斐波那契数列

def fibonacci():

            break
    while len(flist) < int(print_len):
        flist.append(flist[-1] + flist[-2])
    return flist

        ball[choice-1] += 1
    for j in range(10):
        print('选择球{}的概率为：{:.4f}'.format(j+1,ball[j] / sum(ball)))
