从文件中提取信息的最佳方法

发布于 2024-12-10 12:48:32 字数 786 浏览 0 评论 0原文

例如我的文件是：

Game #51236595 Tourney #123698521 Hand #9865653215
player luisgustavo call
player otherplayer fold
player otherother  check

我想以尽可能最好的方式获取信息。请记住，所有文件都是这种格式。变化的是数字和球员

编辑：好的但这不是作业。我已经这样做了几次，但我认为这不是最好的方法。

with open(".myfile", "r") as myfile:
    for line in myfile:
        if "Game" in line:
            game_number = line[line.find('#')+1 : line.find("Tourney")-2]
            tourney_number = line[line.find('Tourney #')+9 : line.find("Hand")-2]
            hand_number = line[line.find('Hand #')+6 : ]
        elif "player" in line:
            player_name = line[line.find(' ')+1 : line.rfind(' ')]
            player_action = line[line.rfind(' ')+1 : ]

该代码运行完美。但我不认为这是一个好的代码一定有更好的方法来做到这一点。

原文

For example my file is:

Game #51236595 Tourney #123698521 Hand #9865653215
player luisgustavo call
player otherplayer fold
player otherother  check

I want to get the information in best way possible.
Remember that all files are in this format. What changes are the numbers and players

EDIT: Ok but this is not a homework.
I've done this a few times but I do not think is the best way.

with open(".myfile", "r") as myfile:
    for line in myfile:
        if "Game" in line:
            game_number = line[line.find('#')+1 : line.find("Tourney")-2]
            tourney_number = line[line.find('Tourney #')+9 : line.find("Hand")-2]
            hand_number = line[line.find('Hand #')+6 : ]
        elif "player" in line:
            player_name = line[line.find(' ')+1 : line.rfind(' ')]
            player_action = line[line.rfind(' ')+1 : ]

The code works perfectly. But I do not think it's a good code must have a better way to do this.

尝试类似的方法

with open('.myfile', 'r') as myfile:
    header = myfile.readline().split()
    game_number, tourney_number, hand_number = header[1], header[3], header[5]
    for line in myfile:
        player_name, player_action = line.split()[1:]

This using split()^{[ docs]} 并且更加Pythonic。

Try something like

with open('.myfile', 'r') as myfile:
    header = myfile.readline().split()
    game_number, tourney_number, hand_number = header[1], header[3], header[5]
    for line in myfile:
        player_name, player_action = line.split()[1:]

This uses split()^[docs] and is much more pythonic.

您可以将 csv.reader 与自定义方言结合使用，以获得已排序大量详细信息的通用解决方案。

基于上面 @brc 给出的答案：

with open(".myfile", "r") as myfile:
    for line in myfile:
        parts = line.split()

        if parts[0] == 'Game':
            game_tag, game_number, tourney_tag, tourney_number, hand_tag, hand_number = parts
            continue

        player_tag, player_name, player_action = parts

这清楚地以最小的开销提取了您需要的部分。当然，您还需要对这些值进行实际操作。另外，我假设一个文件中可以有多个“游戏”行。如果这不是真的，你可以在第一行检查它。

Building on the answer given by @brc above:

with open(".myfile", "r") as myfile:
    for line in myfile:
        parts = line.split()

        if parts[0] == 'Game':
            game_tag, game_number, tourney_tag, tourney_number, hand_tag, hand_number = parts
            continue

        player_tag, player_name, player_action = parts

This clearly extracts the pieces you need with a minimum of overhead. Of course, you'll also need to actually do something with the values. Also, I'm assuming there can be multiple "game" lines in a file. If that's not true, you can just check for it in the first line.
