I've about 7 years experience coding various software in Python (data intensive, web apps, network app, etc). Today when coding in Python I mostly go to the official Python and Django doc directly, that I have installed locally. I open it about 2 to 8 times a day (4-6 hours span) depending on how well I'm familiar with the library I'm dealing with.

For more general questions not covered in the doc I Google about twice to 4 times a day in average. I usually go to stackoverflow.com directly to search.

When coding HTML/CSS/Javascript I clearly lookup caniuse.com about 20 times a day to ensure consistent browser support and learn about corner cases.
