C and C++ are radically different that is not an accurate comparison. Python 3 has many minor breaking changes and few bigger changes. Most huge codebases that support 3 have huge amount of support code that makes it compatible with 2. Probably 80% of the changes in 3 could've been done in an backwards-compatible way, but they actively chose not to. I'm still surprised that python survived it, the update was so incompetently done. Just the huge amount of wasted developer resources on this mostly unnecessary update is staggering.
