I'm fairly sure Python would throw an error if you treated that as a regular expression.

Success is when one remains true to self & others. If we must use Python, then - Any of these is considered False: None, '', [], (), {} and False itself. So, one is bound to achieve success by being truthful to self and others, always create value and make no empty promises and know when to "raise" an exception. Never giving up but knowing when to abandon a bad venture can also be seen as success.

There must be some +ve energy between a startup & an investor. Timing is also everything. Investors can only invest in so many pet food startups. While a pet food startup is making money and is considered a success, that doesn't mean investors have to invest.

Investors sometimes walk away from a B-team founders of a startup no matter how successful the startup really is. A-team with B-plan is always prefered over B-team with A-plan.

Sometimes, Founders decide not take money from investors, if they believe that the investor may only bring money and without any intellect and/or networking.

With that said, the final transaction is not everything.
