学前班一年级上册20以内口算加减法，乱序_20以内加减法打乱顺序-优快云博客

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
