Perks of Being a Python Core Developer (via) Mariatta Wijaya provides a detailed breakdown of the exact capabilities and privileges that are granted to Python core developers - including commit access to the Python main, the ability to write or sponsor PEPs, the ability to vote on new core developers and for the steering council election and financial support from the PSF for travel expenses related to PyCon and core development sprints.
