学前班 一年级上册20以内口算加减法,乱序

该代码示例展示了Python中加法与减法的实现,并通过for循环遍历21x21范围内的整数对,打印出和小于21及差大于等于0的组合。此外,讨论了如何将结果导入Excel,乱序后放入Word并分栏打印。
def sum(x,y):
    z = x + y
    return z

def sub(x,y):
    z = x - y
    return z



if __name__ == '__main__':
    for x in range(21):
        for y in range(21):
            if(sum(x,y)<21):
                print('%d + %d =  ' % (x, y))
    for x in range(21):
        for y in range(21):
            if(sub(x,y)>=0):
                print('%d - %d =  ' % (x, y))

输出的结果,放入excel中,增加一列 rand()

乱序后,再放入word中,分多栏打印就好
