Depends on the company. I would not hire any programmer who only knows python. I am a silicon valley CTO. This shows a technologist at the very earliest stages of their development. Going carefully through online courses in Node/Javascript, Java, Scala, Objective C, Go, Ruby, PHP and writing example programs in each one should take you more than a few months of nights and weekends, but is the kind of work a programmer enjoys. In my first 10 years in the valley, I worked most weekend on my own projects, I would occasionally take a full weekend off. I still have to learn new things many weekends, just to keep up. The good news: no one cares about "certification" or "classes". The bad news: you're on your own. Learn a few languages. Should you take the job? If you want to be a programmer, what's the environment where you'll be able to learn on your own? Which gives you the most free time, and access to Gurus?
