打印一个文件中的数字表，然后求出每列的平均值

def print_and_calculate_average(file_path):
    # 读取文件
    with open(file_path, 'r') as file:
        content = file.read()

    # 解析数字表
    rows = content.split('\n')
    table = [row.split('\t') for row in rows]

    # 打印数字表
    for row in table:
        print('\t'.join(row))

    # 计算每列平均值
    num_columns = len(table[0])
    averages = [0] * num_columns
    for row in table:
        for i, num in enumerate(row):
            averages[i] += float(num)

    for i in range(num_columns):
        averages[i] /= len(table)

    # 输出结果
    print("每列的平均值：")
    for i, average in enumerate(averages):
        print(f"第{i+1}列的平均值为：{average}")

# 调用函数并传入文件路径
