user60125: I need a good library for bitcoin and other BTC-like cryptocurrencies in python.
I'm looking for something similar to bitcoinjs but in python. 
Minimal requirements: 

generate an EC keypair and get public address from the public key
generate an EC keypair and compress it to WIF format.
get an EC keypair from WIF
generate a number of EC keypairs (a HD wallet) from a given seed
build a transaction 
broadcast transaction

If you know any good cryptocurrency libraries let me know!

user30511: Check-out the node-directory within my Github repo experimenting with a scalable cryptocurrency.

user63817: Take a look at Peter Todd's python-bitcoinlib.
From the github repo:

This Python2/3 library provides an easy interface to the bitcoin data structures and protocol. The approach is low-level and "ground up", with a focus on providing tools to manipulate the internals of how Bitcoin works.
