尝试使用re.VERBOSE获取输出

我正在尝试更改模式代码，如图所示

我尝试了一些代码，但未显示任何内容，因为它未返回任何内容

原始

    taf_header_pattern = """
        ^
        (TAF)?    # TAF header (at times missing or duplicate)
        \s*
        (?P<type> (COR|AMD|AMD\sCOR|COR\sAMD|RTD)){0,1}
        \s* # There may or may not be space as COR/AMD/RTD is optional
        (?P<icao_code> [A-Z]{4}) # Station ICAO code
        \s* # at some aerodromes does not appear
        (?P<origin_date> \d{0,2}) # at some aerodromes does not appear

        (?P<origin_minutes> \d{0,2}) # at some aerodromes does not appear
        Z? # Zulu time (UTC, that is) # at some aerodromes does not appear

test_string02 = "KGEG FIXED BASE AMD02 COR01 3119Z-0110Z 311958Z"

header_taf = re.match(taf_header_pattern, string, re.VERBOSE)

print(header_taf)

它不返回不应执行的操作

这有效

在正则表达式中使用模式
