First, install nodejs if its not on your system already:

apt-get update
apt-get -y install curl
curl -sL https://deb.nodesource.com/setup_10.x | bash
apt-get -y install nodejs

Then install from Pypi packages:

pip3 install eosjs_python

Or from source(if you want to contribute) :

git clone https://github.com/EvaCoop/eosjs_python
cd eosjs_python
python3 setup.py develop

You also need eosjs as a node dependency. You could install it globally

npm install -g eosjs

Or can also install it in the js subdirectory within this package

cd js && npm install

	'key_provider': '5JhhMGNPsuU42XXjZ57FcDKvbb7KLrehN65tdTQFrH51uruZLHi'
})

#cleos push action eosio.token transfer '["eva","rider1","1 EVA","initial balance"]' -p eva

eos.push_transaction('eosio.token','transfer','eva','active',{
	"from":"eva",
	"to":"rider1",
	"quantity":"1 EVA",
	"memo":""
})

eos = Eos({
	'http_address': 'http://127.0.0.1:8888',
	'key_provider': '5JhhMGNPsuU42XXjZ57FcDKvbb7KLrehN65tdTQFrH51uruZLHi'

    'key_provider': '5KR93vcDVtJJ8eZ3td4gU87p8PPhsfgK5NZKyDij83kSRJ2UTrM'
})

eos.get_currency_balance('eosio.token', 'xcdzdbkqamvu', 'EVA')
