tkinter 抽奖小程序

团队聚会,难免抽奖环节,这里就需要一个抽奖小程序,于是花2个小时用tkinter快速实现了一个比较灵活实用的小程序。

图1

程序已打包好如图1,peopleList.csv 是参与抽奖名单。

运行程序,双击lucky_Gift.exe 如图2


图2

在小窗口中可以设置抽奖人数,是否允许重复抽取,同时抽动过程中可以让名单滚动起来如图3,可以导出抽奖记录csv格式,默认以导出时间命名。


图3

这里面有个细节,python 读取csv 用pandas 很方便,但是打包成exe就头疼了,就为了读个csv让打包后的程序大了好几倍,不划算,于是自己实现了一个读取和写csv的函数。大大提高了程序运行效率。

读取csv代码如下:

# -*- coding: utf-8 -*-

def read_csv(path):
    try:
        keys = []
        list_dict = []
        with open(path,'r',encoding='utf-8') as file:
            for index,line in enumerate(file.readlines()):

                if index == 0:
                    line = line[1:]
                    line = line.strip()
                    row = line.split(',')
                    keys = row
                else:
                    line = line.strip()
                    row = line.split(',')
                    dict1 = {}

                    for index2,key in enumerate(keys):
                        dict1[key] = row[index2]
                    list_dict.append(dict1)

        return list_dict
    except Exception as e:
        return []

def to_csv(name,list_dict):
    # print(list_dict)
    try:
        with open(name, 'w', encoding='utf-8') as file:
            s = ''
            for index,dict1 in enumerate(list_dict):
                for key in dict1:
                    dict1[key] = str(dict1[key])
                if index == 0:
                    line1 = '\ufeff' + ','.join(dict1.keys()) + '\n' #“\ufeff”解决Excel 打开不乱码
                    s = s + line1
                lineX = ','.join(dict1.values()) + '\n'
                s = s + lineX
            file.write(s)
    except Exception as e:
        print(e)
