尝试从csv生成字典，但结果为空

import csv

def csv_to_dict(file_path, delimiter=','):
    result = []
    try:
        with open(file_path, mode='r', encoding='utf-8') as csvfile:
            csvreader = csv.DictReader(csvfile, delimiter=delimiter)
            for row in csvreader:
                result.append(row)
    except FileNotFoundError:
        print(f"文件 {file_path} 未找到")
    except Exception as e:
        print(f"读取文件时发生错误: {e}")
    return result

# 使用示例
file_path = 'example.csv'
data_dict = csv_to_dict(file_path)
print(data_dict)
