Hello. I'm trying to run blockchain api from github. https://github.com/blockchain/api-v1-client-python
My code:

from blockchain.wallet import Wallet
wallet = Wallet('identifier', 'password', 'http://127.0.0.1:3000', 'api_code')
newaddr = wallet.new_address()

When i run it i get error:

I think this error is because port 3000 is not open.
I tried to blockchain-wallet-service start --port 80 and blockchain-wallet-service start --port 443
but got errors:
1530693477439 - error: listen EACCES 127.0.0.1:443
1530693477439 - error: listen EACCES 127.0.0.1:80

I really need someone's help. It is very important for me.

Unfortunately it looks like that library is trying to start a socket server, which won't work on PythonAnywhere :-(

can you advise hosting on which I can realize this?

I can't recommend a specific company, but what you need is a VPS -- google around and you should be able to find one that looks good to you.
