打印9*9乘法表（递归或压缩矩阵）python

def print_multiplication_table(row, col):
    if row > 10:
        return  # 递归结束条件
    if col == row:
        print()  # 换行
        print_multiplication_table(row + 1, 1)  # 递归调用下一行
    else:
        print(f"{row-1} * {col} = {(row-1) * col}\t", end="")  # 打印乘法表达式
        print_multiplication_table(row, col + 1)  # 递归调用下一列
 
# 调用函数以打印乘法表
print_multiplication_table(1, 1)

for i in range(1,82):
    col=i%9
    row=i//10+1
    if(col==0):
        col=9
    if(row>=col):
        print(f"{row}*{col}={row*col}", end="\t")
    if row==col:
        print()
