如何用python利用列表推导式求九九乘法表

可以使用两层嵌套的列表推导式来生成九九乘法表。代码如下：

[[f"{i}x{j}={i*j}" for j in range(1, 10)] for i in range(1, 10)]

这段代码会生成一个9x9的列表，每个元素是一个字符串，表示对应的乘法表项。可以使用for循环打印出来。

python用列表推导式完成九九乘法表

可以使用两个for循环来生成九九乘法表中的所有元素，然后使用列表推导式来生成一个包含所有元素的列表。以下是代码示例：

mul_table = [(i, j, i*j) for i in range(1, 10) for j in range(1, 10)]

for i, j, product in mul_table:
    print(f"{i} x {j} = {product}")

这将生成一个包含九九乘法表中所有元素的列表，并打印出每个元素的值。

python用列表推导式生成九九乘法表并输出

# 生成九九乘法表
table = [(i, j, i*j) for i in range(1, 10) for j in range(1, 10)]

# 输出九九乘法表
for i in range(0, len(table), 9):
    for j in range(i, i+9):
        print(f'{table[j][0]} × {table[j][1]} = {table[j][2]:2d}', end='\t')
    print()

输出结果为：
