Lesson5: read_value.py vs Brownie console

[CJ-Rose]

I'm getting confused with the switching between local accounts and Rinkeby accounts. Do we use Brownie console to look at locally deployed contracts, and read_value scripts to look at testnet-deployed contracts?
Also what happened to Ganache? Did we graduate to Brownie and we don't need it any more, because Brownie also gives us addresses to test with?
I guess I'm trying to make a mental map of all these tools and how they relate to each other... and I can't see the forest for the trees?? I'm googling for visual aides but everything is too generic or it's pictures of brownies.
Thanks for any ideas.

Great questions.

I'm getting confused with the switching between local accounts and Rinkeby accounts.

When we work with a local blockchain, the local blockchain is a ganache chain. When brownie spins up a local blockchain, it gives us some fake accounts to work with. We can use also use brownie console to look at contracts on any blockchain. If we look at a testnet with brownie console --network rinkeby we are looking at rinkeby. If we just do brownie console this will be our "default" chain (which defaults to a local ganache chain)

Also what happened to Ganache

Whenever we use the development network (aka, the default network) we are working with a ganache chain that brownie is secretly running in the background for us!

Mental maps are exactly the right way to think about these, thank you for asking these questions.
