How to connect web3 to main ethereum network using python?

Question

I am using web3.py on my private/test network though:

from web3 import Web3, HTTPProvider
w3 = Web3(HTTPProvider("https://private-ip:8545"))

For making connection to my private network i use this method and after performing all the oprations and testing i want to connect my API to main ethereum network.

So, my question is that how can i connect to main ethereum network ?

Just use the URL of a node in the main Ethereum network. That could be one you run or one someone else makes available publicly.

Infura runs one such public node.

So, according to you if i use `https://infura.io/` in `HTTPProvider` in will connect to main ethereum network ? – Abdullah Ahmed Ghaznavi Mar 15 '18 at 10:36
No, but if you use `https://mainnet.infura.io/`, then you will be connected to a node in the main Ethereum network. – user94559 Mar 15 '18 at 10:39
Oohh.. Fine! It seems like i need to sign up for infura first. Is there some other way like connecting via IPCProvider or RPC calls to main network ? – Abdullah Ahmed Ghaznavi Mar 15 '18 at 10:42
You can connect to any node, including one you run yourself. – user94559 Mar 15 '18 at 10:43
Can you provide me a link or some info how to do that ? – Abdullah Ahmed Ghaznavi Mar 15 '18 at 10:45
How to do what? You just enter the URL of the node. – user94559 Mar 15 '18 at 10:45
Oohh.. Ok! Thanks for help! :) – Abdullah Ahmed Ghaznavi Mar 15 '18 at 10:46
