Arguably this is too 1-dimensional a description to be able to say. Having learned Python before Java, spending time with the latter has only helped me understand Python's simplicity. That said, if it was the other way around this same might not apply, since Java will force a certain level of boilerplate, but Python can't force you to not over-complicate things.

Learning the fundamentals of interpreters, compilers, etc. can also give understanding transferable between almost all languages.
