What could be regex which match anystring followed by daily but it must not match daily preceded by m?
什么可以是正则表达式匹配anystring后跟每天，但它必须不匹配每天前面的m？
For example it should match following string
例如，它应匹配以下字符串
beta.daily- beta.daily
abcdaily- abcdaily
dailyabc- dailyabc
daily- 日常
But it must not match
但它一定不匹配
-
mdailyor - mdaily或
-
abcmdailyor - abcmdaily或
mdailyabc- mdailyabc
I have tried following and other regex but failed each time:
我试过跟随和其他正则表达式，但每次失败：
-
r'[^m]daily': But it doesn't match withdaily - r'[^ m]每日'：但它与每日不匹配
-
r'[^m]?daily': It match with string containingmdailywhich is not intended - r'[^ m]？daily'：它与包含mdaily的字符串匹配，这不是预期的

Just add a negative lookbehind, (?<!m)d, before daily:
在每天之前添加一个负面的lookbehind，（？<！m）d：
(?<!m)daily
The zero width negative lookbehind, (?<!m), makes sure daily is not preceded by m.
零宽度负向后观（？<！m）确保每天不以m为前提。
