what is the right way to explore bitcoin blockchain ?

hi,

I want to explore bitcoin blockchain for instance get address' information, transactions, and so on. what is the right place where I can grab this info. I tried https://blockchain.info but they blocked me because too many requests. Maybe somebody can explain me or point me where I can read the answer on my question?
I would prefer python library but I tend to think I have to install kind of node on my PC and read data from there? can somebody advice me ? if it is wrong place for this question - could somebody pint me right place?
