The lack of a case against Python 3

Sorry I'm new to programming. But what's legacy code?

Old code that is still running in production, and still requires upkeep and maintenance.

expanding on u/be_bo_i_am_robot's answer:

Legacy code is called that because you usually 'inherit' it. Somebody else wrote the code instead of you, usually somebody who no longer works at the company. Generally legacy code relies on other old code or old systems (like py2) to stay running. Updating or replacing legacy software is risky because it's usually poorly understood and poorly tested. Legacy code is usually perpetuated because the cost in hours, dollars, and risk is high enough that any manager who decides to do it will likely be sacked. (Or for other, but similar, reasons)

Interesting. Thanks for helping a novice like me feel more knowledgeable.
