python - 如果匹配可以是单个字符串或字符串元组，如何测试字符串中是否存在匹配？

Question

我正在尝试从文本文件中进行直接字符串匹配。有时，匹配意味着一个字符串包含多个目标字符串。目前我的代码看起来像

interesting_matches = [
    "sys/bootdisk.py",
    " engine stalled for ",
    " changed to stalled)",
    "DSR failure",
    "Detected IDI failure",
    "idi_shallow_verify_failure",
    "Malformed block history",
    "Out of order sequence message on",
    "Port reset timeout of",
    "gmp_info",
    "test_thread",
    " panic @ time ",
    ": *** FAILED ASSERTION",
    "filesystem full",]

    for match in interesting_matches:
        # Iterate through simple matches.
        if match in line:
            processed_line_data = self._process_line(
                match,
                line,
                line_datetime,
                line_num,
                current_version)

    if "kern_sig" in line and "pid" in line:
        processed_line_data = self._process_line(
            ("kern_sig", "pid"),
            line,
            line_datetime,
            line_num,
            current_version)

    if "vfs_export" in line and "ignoring" in line:
        processed_line_data = self._process_line(
            ("vfs_export", "ignoring"),
            line,
            line_datetime,
            line_num,
            current_version)

    if "job_d" in line and
        "State transition from state " in line and
        " took longer than " in line:
        processed_line_data = self._process_line(
            (
                "job_d",
                "state transition from state",
                " took longer than "),
            line,
            line_datetime,
            line_num,
            current_version)

    if processed_line_data is not None:
        return_list.append(processed_line_data)

我想做的是类似的事情

interesting_matches = [
        "sys/bootdisk.py",
        " engine stalled for ",
        " changed to stalled)",
        "DSR failure",
        "Detected IDI failure",
        "idi_shallow_verify_failure",
        "Malformed block history",
        "Out of order sequence message on",
        "Port reset timeout of",
        "gmp_info",
        "test_thread",
        " panic @ time ",
        ": *** FAILED ASSERTION",
        "filesystem full",
        ("kern_sig", "pid"),
        ("vfs_export", "ignoring"),
        ("job_d", "State transition from state", " took longer than "),]

for matches in interesting_matches
     if any(match in line for match in matches):
           processed_line_data = self._process_line(
               match,
               line,
               line_datetime,
               line_num,
               current_version)

但是元组和字符串的混合会导致值错误，指出您无法比较字符串和元组。

如果我想检查单个和多个字符串，如何编写单个比较？

编辑:

这是基于 Sean 回答的工作代码

interesting_matches = [
    ("sys/bootdisk.py",),
    (" engine stalled for ",),
    (" changed to stalled)",),
    ("DSR failure",),
    ("Detected IDI failure",),
    ("idi_shallow_verify_failure",),
    ("Malformed block history",),
    ("Out of order sequence message on",),
    ("Port reset timeout of",),
    ("gmp_info",),
    ("test_thread",),
    (" panic @ time ",),
    (": *** FAILED ASSERTION",),
    ("filesystem full",),
    ("kern_sig", "pid"),
    ("vfs_export", "ignoring"),
    ("job_d", "State transition from state", " took longer than "),]

for matches in interesting_matches:
    if all(match in "test_thread" for match in matches):
        print(matches)

非常可行。试试这个:对于单子(monad)字符串签名，无论如何将它们包装在一个元组中。现在你的列表是同质的，你的问题变得简单多了。对于每个签名元组，检查签名中的所有子字符串是否也在该行中。
