 I am trying to create a match program with 4 fields. There will be 4 games going on at the same time, one at each fields.

一支球队永远不会连续打 2 场比赛 - 并且不能同时在多个场地上比赛。对于 32 个匹配项和 4 个字段，这可能是不可能的。

我正在尝试使用 Python 以尽可能少的错误创建最佳匹配程序。然后，使用错误最少的程序 - 在发生错误的地方创建一个暂停，以便团队有机会休息。

这是我的 matches.txt 文件 Team1、Team2、Team1 ID、Team 2 ID

    if errors < minErrors:
        minErrors = errors
        f = open("pymatches.txt", "a+")
        f.truncate(0)
        f.write(str(errors) + "\n")
        for line in pyMatches:
            if line:
                f.write(line + "\n")
        f.close()
        if errors == 0:
            break
    i += 1

它产生 0 个错误，但仍然会有一支连续打 2 场比赛的球队。我看不出这怎么可能？
