Going from no Python to intermediate proficiency is associated with a $14,000–$22,000 annual salary increase for data-adjacent roles (analyst, data scientist, product manager). In pure software engineering roles, the difference between no Python and intermediate Python is $18,000–$30,000/year in base salary. The Google IT Automation with Python Certificate ($300, 6 months) produces an estimated 10-year NPV of $100,000–$160,000.
