So basically i am trying to create my own crypto wallet application in python, i have generated the random entropy, calculated the checksum, generated the 12 words and then generated the root seed using pbkdf2, but after generating the seed I'm kinda lost, i dont know how i can generate the master key and the chaincode, and then generating the public and private keys, lets put for example i have this root seed 1f8c67bc66355f62f6c63752803599cc6e4a05eac6dd63e05e858329f3656ed3c868bd428a4218b4eb92e0fe5e774874c4ab270b8d1377ddc0aea6a797682342
what should i do with it to generate the master private key and then the following child public/private keys? thanks, i'm very new to this in general so sorry if there is any issue with my question
