Question

到目前为止，这是我的代码：

    n = int(input("Please enter a number between 1 and 10: "))
    if n > 10:
        n = int(input("Please enter a smaller number (must not be greater than 10): "))

    for k in range(1, n+1):
        print(k, end=" ")
        print('-' * 10, end=" ")
    print()

    for i in range(1, n+1):
        print(i, end=" ")
        for j in range(1, n + 1):
            print(i * j, end=" ")
        print()

假设用户输入4为n，我需要显示一个如下所示的乘法表：

1 2 3 4
----------
1 | 1 2 3 4
2 | 2 4 6 8
3 | 3 6 9 12
4 | 4 8 12 16

当前标题如下：

1 ----------- 2 ---------- 3 ----------- 4 ----------

我想念什么？破折号应位于自己的行上。我曾尝试在包括i和j循环在内的不同位置插入标头的行，包括破折号。

Answer 1

您需要将行print('-' * 10, end=" ")移到for循环之外，因为您不希望脚本打印该标题行一次而不是n次。除此之外，您只需要在行索引之后添加一个小节即可获得向下的边界线。

n = int(input("Please enter a number between 1 and 10: "))
if n > 10:
    n = int(input("Please enter a smaller number (must not be greater than 10): "))

for k in range(1, n+1):
    print(k, end=" ")

print()
print('-' * 10)

for i in range(1, n+1):
    print(i, "|", end=" ")
    for j in range(1, n + 1):
        print(i * j, end=" ")
    print()

Answer 2

您可以使用

n = int(input("Please enter a number between 1 and 10: "))
if n > 10:
    n = int(input("Please enter a smaller number (must not be greater than 10): "))

for k in range(1, n+1):
    print(k, end=" ")
    # print('-' * 10, end=" ")
print()
print("----------")

for i in range(1, n+1):
    print(i, end=" | ")
    for j in range(1, n + 1):
        print(i * j, end=" ")
    print()

输出

Please enter a number between 1 and 10: 4
1 2 3 4
----------
1 | 1 2 3 4
2 | 2 4 6 8
3 | 3 6 9 12
4 | 4 8 12 16

我如何格式化该乘法表，如图所示？
