import pandas as pd
import numpy as np
# 读取Excel文件
excel_data = pd.read_excel('order.xlsx', sheet_name='Sheet')
# 提取第一列的数值数据并转换为字符串数组
string_array = excel_data.iloc[:,0].astype(str).tolist()
#存储硬盘
np.save('order.npy',string_array) 
#打印结果
print(string_array)

要实现前要安装python3 并安装相应的依赖库

pip install openpyxl

pip install pyzbar

#pip install Pillow
from pyzbar.pyzbar import decode
from PIL import Image
def decode_qr_code(image_path):
    # 打开图片
    image = Image.open(image_path)
    # 使用pyzbar的decode函数解码图片中的二维码
    decoded_objects = decode(image)
    # 输出解码结果
    for obj in decoded_objects:
        print('Type:', obj.type)
        print('Data:', obj.data.decode('utf-8'))  # 解码数据为utf-8格式
        print('Location:', obj.rect)  # 输出二维码在图片中的位置
# 调用函数，传入图片路径
decode_qr_code('I:/winpython/erweima.jpg')
