在regex verbose中使用Pattern

Question

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，但它没有显示任何内容，因为它没有返回任何代码

原版的

    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

变

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

print(header_taf)

它没有返回它不应该做的事情
