如何将CSV文件中的int值存储在单独的二维数组元素中

import csv

def read_csv_file(file_path):
    data = []
    with open(file_path, 'r') as file:
        csv_reader = csv.reader(file)
        for row in csv_reader:
            data.append(row)
    return data

def convert_to_int(data):
    int_data = []
    for row in data:
        int_row = []
        for value in row:
            int_row.append(int(value))
        int_data.append(int_row)
    return int_data

def store_int_values_in_array(file_path):
    data = read_csv_file(file_path)
    int_data = convert_to_int(data)
    return int_data

# 调用示例
file_path = 'data.csv'
int_array = store_int_values_in_array(file_path)
print(int_array)
