[GUI]汇总多个 Excel 文件中的数据到一个新的 Excel 文件中

uupython阅读(1247)

这段代码是一个使用 PyQt5(一个 Python 的 GUI 库)编写的桌面应用程序,用于汇总多个 Excel 文件中的数据到一个新的 Excel 文件中。让我来为你解析一下代码的主要部分:

  1. 首先,导入了必要的模块和库:
   import sys
   import os
   from PyQt5 import QtWidgets
   from PyQt5.QtGui import QIcon
   import xlrd
   import datetime
   import time
   from openpyxl import Workbook
   from openpyxl.styles import Border, Side, PatternFill, Font, GradientFill, Alignment
  1. 创建了一个继承自 QtWidgets.QMainWindow 的类 MainGUI,用于构建 GUI 界面。
  2. MainGUI 类中,初始化了应用程序窗口、设置了窗口标题和初始大小,并创建了主要的窗口部件。
  3. 主要窗口部件包括两个文本输入框 self.inputself.output,两个按钮 self.input_btnself.output_btn 用于选择输入和输出文件夹,一个列表部件 self.show_result 用于显示操作结果,以及一个按钮 self.run 用于执行数据汇总操作。
  4. 绑定了按钮的点击事件,分别调用了 Choice_dir_inputChoice_dir_outputSummary_data 函数。
  5. Choice_dir_inputChoice_dir_output 函数通过调用 QtWidgets.QFileDialog.getExistingDirectory 弹出文件夹选择对话框,让用户选择输入和输出文件夹,并将选择的文件夹路径显示在文本输入框中。
  6. Get_data 函数用于从单个 Excel 文件中提取数据,使用 xlrd 库来读取 Excel 文件。
  7. Get_file_path 函数用于获取指定文件夹下所有的 .xls 文件。
  8. Get_current_time 函数用于获取当前的日期和时间。
  9. Summary_data 函数是核心功能,用于汇总多个 Excel 文件的数据到一个新的 Excel 文件中。它会调用前面的函数来获取数据,然后使用 openpyxl 库创建一个新的 Excel 工作簿,将数据写入工作表,并设置单元格样式。
  10. 最后,在 main 函数中创建了应用程序对象,设置应用程序图标,创建 MainGUI 窗口对象,并启动应用程序的事件循环。

这段代码是一个简单的桌面应用程序,用于处理 Excel 文件数据的汇总,通过 GUI 提供了文件选择和操作结果显示的功能。

生成指定格式的虚拟手机号码

uupython阅读(1383)

这段代码用于生成指定格式的虚拟手机号码,并将这些手机号码保存到一个文本文件中。下面是代码的主要功能和逻辑:

  1. generate_phone_number(province, prefix, suffix) 函数用于生成一个虚拟手机号码,其中 province 表示省份代码,prefix 表示前三位号段,suffix 表示后两位号码。生成的号码格式为 province-prefix-6位随机数字-suffix
  2. generate_unique_phone_numbers(num_numbers, province, prefix, suffix) 函数用于生成指定数量的唯一虚拟手机号码。它通过调用 generate_phone_number 函数生成号码,并使用集合 phone_numbers 来确保生成的号码唯一。直到集合中的号码数量达到指定的 num_numbers 时,循环生成号码。
  3. save_phone_numbers_to_file(phone_numbers, filename) 函数用于将生成的手机号码保存到指定的文本文件中。它遍历 phone_numbers 列表,并将每个号码写入文件中,每行一个号码。
  4. 在代码中设置了自定义的省份代码 (custom_province)、前三位号段 (custom_prefix) 和后两位号码 (custom_suffix)。
  5. 调用 generate_unique_phone_numbers 生成了 100 个唯一的虚拟手机号码,并将它们保存到名为 “phone_numbers.txt” 的文本文件中。

最终,代码会在控制台上输出 “Generated Unique Phone Numbers saved to phone_numbers.txt”,指示已生成并保存虚拟手机号码。如果输入的号码格式不正确,则会输出 “Error: Invalid input”。

完整的源码如下:

import random

def generate_phone_number(province, prefix, suffix):
    if len(province) != 2 or len(prefix) != 3 or len(suffix) != 2:
        return None
   
    middle_digits = ''.join(str(random.randint(0, 9)) for _ in range(6))
    phone_number = f"{province}-{prefix}-{middle_digits}-{suffix}"
    return phone_number

def generate_unique_phone_numbers(num_numbers, province, prefix, suffix):
    phone_numbers = set()
    while len(phone_numbers) < num_numbers:
        phone_number = generate_phone_number(province, prefix, suffix)
        if phone_number:
            phone_numbers.add(phone_number)
    return list(phone_numbers)

def save_phone_numbers_to_file(phone_numbers, filename):
    with open(filename, 'w') as file:
        for number in phone_numbers:
            file.write(number + '\n')

custom_province = "HE"  #省份代码
custom_prefix = "151"   # 前三位
custom_suffix = "27"    # 后二位
output_file = "phone_numbers.txt"

generated_numbers = generate_unique_phone_numbers(100, custom_province, custom_prefix, custom_suffix)
if generated_numbers:
    save_phone_numbers_to_file(generated_numbers, output_file)
    print("Generated Unique Phone Numbers saved to", output_file)
else:
    print("Error: Invalid input")

你可以将这段代码保存为一个 `.py` 文件,然后运行它。运行后,它将生成并保存指定数量的虚拟手机号码到名为 “phone_numbers.txt” 的文本文件中。确保设置了 `custom_province`、`custom_prefix` 和 `custom_suffix` 来自定义号码的格式。

使用python和opencv实现的颜色位置定位与具体色值提取

uupython阅读(1515)

这段代码用于分析图像中的颜色信息并根据颜色值的平均值来判断是接近黄色还是接近紫色。具体步骤如下:

  1. 读取图像:
  • 使用OpenCV的cv2.imread方法读取指定路径下的图像。
  1. 定义需要识别的颜色及其阈值范围:
  • 颜色以RGB颜色空间的阈值范围表示,存在一个颜色字典color_dist,其中包括了需要识别的颜色(’pink’和’yellow’)及其对应的阈值范围。
  1. 对图像进行高斯模糊和颜色空间转换:
  • 使用高斯模糊来平滑图像。
  • 将图像从BGR颜色空间转换为HSV颜色空间,以便更好地处理颜色信息。
  1. 使用腐蚀操作:
  • 使用cv2.erode方法对HSV图像进行腐蚀操作,以消除噪点,使边缘更加清晰。
  1. 查找颜色区域块:
  • 针对每个需要识别的颜色,使用cv2.inRange方法找到在阈值范围内的颜色区域。
  • 使用cv2.findContours方法查找颜色区域的轮廓。
  1. 获取最大颜色区域:
  • 从所有颜色区域中选择面积最大的区域,将其用矩形框出。
  1. 随机生成20个点位:
  • 随机生成20个点位坐标,用于计算平均颜色值。
  1. 计算20个点位的平均颜色值:
  • 遍历这些点位,获取每个点位的颜色值,然后计算这些颜色值的平均值。
  1. 判断平均颜色值接近哪种颜色:
  • 通过计算平均颜色值与黄色和紫色的颜色距离,判断平均颜色值接近哪种颜色。
  1. 输出结果:
  • 根据颜色判断结果,输出是阴性还是阳性。
  • 绘制矩形框和随机点位到图像上,以可视化显示结果。
  1. 显示图像:
    • 使用OpenCV的窗口来显示处理后的图像。

代码中的cv2.namedWindowcv2.imshow方法用于创建窗口并显示图像。最终,根据平均颜色值的判断结果,会在控制台输出相应信息,并在图像上绘制矩形框和随机点位以可视化显示结果。

    colorArr += c

rect = cv2.minAreaRect(mask)

    avg_color += color
avg_color = tuple(map(int, avg_color / len(points)))

# 判断平均颜色值接近黄色还是接近紫色
yellow_dist = np.linalg.norm(avg_color - color_dist['yellow']['Lower'])

爬取生态环境中心每日核辐射检测

uupython阅读(1248)

这段代码用于从网页上抓取数据,并将数据保存到文本文件中。主要步骤如下:

  1. 发送HTTP请求获取网页内容:
  • 使用requests.get方法发送GET请求,获取指定网页的HTML内容。
  1. 使用XPath解析HTML内容:
  • 使用lxml库的etree.HTML方法将HTML文本解析成HTML树。
  • 使用XPath表达式定位网页中的数据。
  1. 遍历HTML元素获取数据:
  • 使用XPath表达式选中需要抓取的数据元素。
  • 遍历每个元素,提取城市、辐射值和检测时间等数据。
  • 将提取的数据构建成字典,并将字典添加到名为datas的列表中。
  1. 写入数据到文本文件:
  • 打开一个文本文件以写入模式,文件名格式为data_日期.txt
  • 遍历datas列表,将每个数据字典的内容格式化为字符串,并写入文本文件。
  • 使用datetime.datetime.now().strftime("%Y%m%d")获取当前日期作为文件名的一部分。

总体来说,这段代码通过HTTP请求和XPath解析,从指定网页上抓取了数据,然后将数据保存到文本文件中,文件名包括日期信息。

青少年读本打包下载

uupython阅读(1405)

这段代码是一个用于批量下载青少年读本文件的脚本,它使用了多线程的方式进行文件下载。以下是代码的主要功能和流程:

  1. 导入所需模块:导入了requests、os和ThreadPoolExecutor模块。
  2. 定义青少年读本文件列表URL:url变量存储了获取青少年读本文件列表的URL。
  3. 定义下载目录:download_dir变量存储了下载文件的目录路径。
  4. 定义下载集合:download_lists变量用于存储下载任务,每个任务由文件的下载链接和保存路径组成。
  5. 定义download_list函数:该函数发送HTTP请求获取青少年读本文件列表的JSON数据,然后遍历每个文件项,提取文件的下载链接和保存路径,并将任务添加到download_lists集合中。
  6. 定义download函数:该函数接收文件的下载链接和保存路径作为参数,通过requests.get方法下载文件内容,然后保存到指定的输出路径。
  7. 主程序入口:在if __name__ == '__main__':中,首先调用download_list函数获取下载任务列表,然后使用ThreadPoolExecutor创建线程池,最大线程数为10。遍历download_lists中的每个任务,使用executor.submit方法提交下载任务给线程池。

这段代码实现了并发下载多个文件的功能,通过多线程的方式加速文件下载过程。需要注意的是,在使用多线程下载时,要注意设置适当的线程数,以避免对目标服务器造成过多的并发请求。同时,也要注意文件保存路径的创建,确保保存文件的目录存在。
