Python中的复杂数据提取
Python中的复杂数据提取
提问于 2018-01-10 08:10:19
我需要有人帮我启动一个程序。我每周都会在网上玩几场扑克比赛。事实证明，我使用的网站记录手的历史，并将它们保存到我的硬盘驱动器作为.txt文件。不幸的是，数据的格式有点粗糙。我想要创建一个程序，以每一只手，并告诉我多少我赢或输。我从下面的一只手上粘贴了一个样本，我想从每只手中提取以下信息。
- 百叶窗和安特。在你向下滚动的例子中，你可以看到“播放器8有小盲(250)”和“播放器1有大盲(500)”。上面提到的每一个玩家“玩家英雄(50)”的antes。在这种情况下，小盲= 250，大盲= 500，ante = 50。
- 我的堆栈大小。我把我的球员称为“英雄”。我的堆栈大小在第6行，上面写着“座位3:英雄(17595)”。在这种情况下，我的堆栈大小是17595。
- 我的手。在这个例子中，表示“玩家英雄接收卡: 10c；Player Hero接收卡:7H”。所以我的手是"10c7h“
- 的玩家数量。在的样本中，有8个播放器。
- 我的位置。这个可能很棘手。我决定从“大盲”开始，并将其赋值为0。小盲= 1，按钮= 2，这在某种程度上违反了“扑克逻辑”，但从编程的角度来看，对我来说更有意义，因为总有一个大盲，而其他一些位置将取决于有多少玩家在桌子上。
- 损益。--这是文本底部的“汇总”标签。“玩家英雄不显示cards.Bets: 50。收藏: 0。输:50。”在这种情况下，我的利润是-50 (即损失50)，这意味着我支付了50赌注和折叠我的手。
下面是.txt文件的外观。注意这是一只手。在实际的.txt文件中，这只手将被几十个或数百个其他手跟随。开头总是用“游戏开始”来表示，最后一行总是表示“游戏结束”。

HandNumber = 000001
BigBlind = 500
Ante = 50
Players = 8
StackSize = 17595
Hand = 10c7h
Position = 6 # small blind = 1; add 5 since I'm 5 positions removed
Profit = -50我的经验水平：--我已经学习了大约6个月的开发、数据科学和SQL的在线课程。我对课程有些熟悉，但对自己的课程却没有太多的经验。我设计了一些程序来帮助使用正则表达式从财务报表中提取数据。

这将是最容易解决的使用正则表达式分裂不同的游戏，然后更多的正则表达式提取信息。我会上一堂课来保存所有这些信息。然后可以使用db或json存储这些信息。
def split_file(file_handle):
pat_str = '''\
^Game started at: (?P<game_start>.*?)
(?P<game>.*?)
^------ Summary ------
(?P<summary>.*)
^Game ended at: (?P<game_end>.*)$\
'''
pat = re.compile(pat_str, flags=re.MULTILINE|re.DOTALL)
text = file_handle.read()
for game in pat.finditer(text):
yield game
class Pokergame:
def __init__(self, game_info, playername = 'Hero'):
self.game_start = datetime.datetime.strptime(game_info['game_start'], "%Y/%m/%d %H:%M:%S")
self.game_end = datetime.datetime.strptime(game_info['game_end'], "%Y/%m/%d %H:%M:%S")
self.game_info = _parse_game(game_info['game'], playername)
self.summary = _parse_summary(game_info['summary'], playername)
def _parse_game(game_str, playername):
pattern_seat = f'Seat (\d+): {playername} \((\d+)\).'
seat_match = re.search(pattern=pattern_seat, string=game_str)
if seat_match:
seat, stack = seat_match.groups()
pattern_cards = f'Player {playername} received card: \[(?P<card>\w+)\]'
cards = tuple(i['card'] for i in re.finditer(pattern_cards, game_str))
result = {
'seat': seat,
'stack': stack,
'cards': cards,
'text': game_str,
}
return result
def _parse_summary(summary_str, playername):
return summary_str
games = []
with StringIO(hand_text) as file_handle:
for game_info in split_file(file_handle):
games.append(Pokergame(game_info))我使用StringIO来模拟open(file)。您将不得不充实__init__和_parse_...，但这将使您走上正确的轨道。
如果您有多个文件，可以使用itertools.chain连接游戏。
games.game_info
{'cards': ('10c', '7h'),
'seat': '3',
'stack': '17595',
'text': "Game ID: 1094127759 250/500 $5,000 GTD, ...\nPlayer Player4 mucks cards"}页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
