🍈 一、快递分练小程序

 🍉二. 综合实战-股票数据分析&处理

 🍉二. 炸金花

🍈 一、快递分练小程序

• 数据源为嵌套列表
• 结果为字典样式，key为省份，value为嵌套列表
• 取前三字符判断是否可行，特殊区域特殊处理

1.嵌套列表

infos=[
    ['王*龙', '北京市海淀区4层'],
    ['庞*飞', '北京市昌平区四楼403'],
]
print(infos[0])
print(infos[0][0])

结果
['王*龙', '北京市海淀区4层']
王*龙

 2.切片的进阶

 

# -*- coding: utf-8 -*-
infos=[
    ['王*龙', '北京市海淀区4层'],
    ['庞*飞', '北京市昌平区四楼403'],
    ['顾*锐', '江苏省扬州市畜禽有限公司'],
    ['王*飞', '上海市徐汇区广场B座5E'],
    ['华*升', '北京市海淀区大厦'],
    ['朱*锴', '上海市浦东新区'],

    ['司*鹏', '河南省鹤壁市'],
    ['聂*睿', '河北省石家庄市'],

results = {}
others = ['新疆','宁夏']
print("-----分练开始-----")
for info in infos:
    province = info[1][:3]
    if info[1][:2] in others:
        province = info[1][:2]
    if province in results:
        results[province].append(info)
    else:
        results[province] = [info]

    print(f"\t'{province}':[")
    for value in results[province]:
        print(f"\t\t{value},")
    print(f"\t],")
print('}')
结果：

 🍉二. 综合实战-股票数据分析&处理 把以下股票数据存⼊ stock_data.txt 开发程序对 stock_data.txt 进⾏以下 *** 作： 1. 程序启动后，给⽤户提供查询接⼝，允许⽤户᯿复查股票⾏情信息 ( ⽤到循环 ) 2. 允许⽤户通过模糊查询股票名，⽐如输⼊ “ 啤酒 ”, 就把所有股票名称中包含 “ 啤酒 ” 的信息打印出来 3. 允许按股票价格、涨跌幅、换⼿率这⼏列来筛选信息，⽐如输⼊ “ 价格 >50” 则把价格⼤于 50 的股票 都打印，输⼊ “ 市盈率 <50“ ，则把市盈率⼩于 50 的股票都打印，不⽤判断等于。 思路提示：加载⽂件内容到内存，转成 dict or list 结构，然后对 dict or list 进⾏查询等 *** 作。 这样以后 就不⽤每查⼀次就要打开⼀次⽂件了，效率会⾼。

# 1. 程序启动后，给用户提供查询接口，允许用户**重复查**股票行情信息。
#
import re

stock_dic = {}
f = open("stock_data.txt", encoding="utf-8")

headers = f.readline().strip().split(",")

for line in f:
    line = line.strip().split(",")
    stock_dic[line[0]] = line
f.close()

# for i,j in stock_dic.items():
#     print(i,j)


while True:
    cmd = input("请输入要查询的股票指令")

    for s_id, s_data in stock_dic.items():
        s_name = s_data[1]
        if cmd in s_name:
            print(s_data)

    # if cmd == "退出":
    #     break

# 2. 允许用户通过**模糊查询**股票名，比如输入“啤酒”,
# 就把所有名称当中包含啤酒的股票都打印出来。
#
# 3. 允许按 **当前价、涨跌幅、换手率**这几列来筛选信息，
# 比如输入**“当前价>50**”则把价格大于50的股票都打印，
# 输入“**涨跌幅<50**“，则把涨跌幅小于50的股票都打印，不用判断等于。

# 格式是否合法（正则表达式）
    cmd_parser = re.split("[<>]", cmd)
    if len(cmd_parser) != 2:
        continue

# 列名是否合法
    filter_column, filter_val = cmd_parser
    if filter_column not in ["当前价", "涨跌幅", "换手率"]:
        continue

# 数值的合法性
    try:
        filter_val = float(filter_val)
    except ValueError:
        continue

# 根据列名，找到想查的列的索引
    column_index = headers.index(filter_column)

    for s_id, s_data in stock_dic.items():
        if ">" in cmd:
            if float(s_data[column_index].strip("%")) > filter_val:
                print(s_data)
        else:
            if float(s_data[column_index].strip("%")) < filter_val:
                print(s_data)




结果
请输入要查询的股票指令N晶科
['SH601778', 'N晶科', '6.29', '+1.92', '+43.94%', '+43.94%', '259.66万', '1625.52万', '0.44%', '22.32', '-', '173.95亿']
请输入要查询的股票指令

 🍉二. 炸金花

# 一付扑克牌，去掉大小王，每个玩家发3张牌，最后比大小，看谁赢。
#
# 有以下几种牌：
#
# 豹子：三张一样的牌，如3张6.
#
# 顺金：又称同花顺，即3张同样花色的顺子， 如红桃 5、6、7
#
# 顺子：又称拖拉机，花色不同，但是顺子，如红桃5、方片6、黑桃7，组成的顺子
#
# 对子：2张牌一样
#
# 单张：单张最大的是A
#
# 这几种牌的大小顺序为， **豹子>顺金>同花>顺子>对子>单张**


# 单牌之间如何比大小
# A：红桃J 红桃K 黑桃A  11 + 130 + 1400 = 1541
# B：方片2 方片2 梅花3  2 + 20 + 300 = 322 * 10 = 3220

# 不同牌型之间如何比大小
# 如何判断玩家是什么牌(不同牌型有不同的判断方法) 高内聚 低耦合
