显示错误、矩阵、向量的python函数，读取csv文件

try:
    # 代码块
except Exception as e:
    print("发生错误：", str(e))

import numpy as np

# 创建矩阵
matrix = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]])
print("矩阵：")
print(matrix)

# 创建向量
vector = np.array([1, 2, 3])
print("向量：")
print(vector)

import csv

# 打开CSV文件
with open('data.csv', 'r') as file:
    # 创建CSV读取器
    reader = csv.reader(file)
    
    # 逐行读取并显示内容
    for row in reader:
        print(row)
