let the official steem-python be as easy to use as beem? Dynamically search for available steem API nodes

steem-python :is Steem the official Python library, has a bip38 encryption wallet and a practical cli utility(steempy).

However, for many Chinese users, the pain is that the official steem API node is often inaccessible.

<p dir="auto">The advantage of beem is that it can automatically find the available steem API nodes. Most of the time, you don't need to worry about network access. <p dir="auto">So how to make the official steem-python as easy to use as beem? We can also try to use the function of dynamic switching the steem API node in the steem-python program. <h2>Dynamically switch the stem API node <p dir="auto">Demonstration program (dynamic_nodes.py): <pre><code>import steembase import steem from steem.steemd import Steemd from steem.account import Account from steem.blockchain import Blockchain steemd_nodes = [ 'https://anyx.io', 'https://steemd.minnowsupportproject.org', 'https://rpc.esteem.app', 'https://api.steemit.com', 'https://api.steem.house', 'https://gtg.steem.house:8090', 'https://appbasetest.timcliff.com', ] custom_instance = Steemd(nodes=steemd_nodes) tmpAccount = Account('dappcoder', steemd_instance=custom_instance) print('tmpAccount:', tmpAccount) print('') tmpBlockchain = Blockchain(mode='head', steemd_instance=custom_instance) print('tmpBlockchain:', tmpBlockchain) <p dir="auto">run it:<code>python dynamic_nodes.py
