Python九九乘法表代码实例详解

下面是一个简单的Python代码示例，用于打印九九乘法表：

pythonCopy codefor i in range(1, 10):
    for j in range(1, i + 1):
        print(f"{j} * {i} = {i * j}", end="t")
    print()

运行以上代码，将输出如下的九九乘法表：

Copy code1 * 1 = 1
1 * 2 = 2     2 * 2 = 4
1 * 3 = 3     2 * 3 = 6     3 * 3 = 9
1 * 4 = 4     2 * 4 = 8     3 * 4 = 12    4 * 4 = 16
1 * 5 = 5     2 * 5 = 10    3 * 5 = 15    4 * 5 = 20    5 * 5 = 25
1 * 6 = 6     2 * 6 = 12    3 * 6 = 18    4 * 6 = 24    5 * 6 = 30    6 * 6 = 36
1 * 7 = 7     2 * 7 = 14    3 * 7 = 21    4 * 7 = 28    5 * 7 = 35    6 * 7 = 42    7 * 7 = 49
1 * 8 = 8     2 * 8 = 16    3 * 8 = 24    4 * 8 = 32    5 * 8 = 40    6 * 8 = 48    7 * 8 = 56    8 * 8 = 64
1 * 9 = 9     2 * 9 = 18    3 * 9 = 27    4 * 9 = 36    5 * 9 = 45    6 * 9 = 54    7 * 9 = 63    8 * 9 = 72    9 * 9 = 81

以上代码使用两个嵌套的循环来遍历九九乘法表的每一行和每一列，并使用字符串格式化（f-string）将乘法表达式和结果打印出来。每一行结束后使用print()函数打印一个换行符，以确保每一行的乘法表达式在不同行显示。
