# `[2019-07-21]` hacked seaborn to display vs on pairplots

used inspect to extract directly from local variables, lol  
<https://github.com/mwaskom/seaborn/blob/master/seaborn/axisgrid.py#L1340-L1341>  




## why python is good: patching seaborn bootstrap

I've had nondeterministic behaviour due to random seed  
was not propagated, but with a patch it's possible to achieve  

<https://github.com/mwaskom/seaborn/blob/065d3c1ed58b029d61913cca8fc315cc985ffc91/seaborn/regression.py#L235>  

    # TODO careful.. need to do this ONCE
    bootstrap_orig = sns.algorithms.bootstrap
    def bootstrap_hacked(*args, **kwargs):
        return bootstrap_orig(*args, random_seed=0, **kwargs)
    sns.algorithms.bootstrap = bootstrap_hacked

# hacking logging.Logger to do basicConfig

    logging.basicConfig(
        format='%(asctime)s %(levelname)-8s %(message)s',
        level=logging.INFO,
        datefmt='%Y-%m-%d %H:%M:%S')

However if you are a well-mannered person, you don't want to mess with other loggers and you're probably providing your own logger method  

This is a bit horrible  
<https://stackoverflow.com/a/28330410/706389>  

For my personal projects I'm using logzero which has got a single line setup method. However, for code I'm sharing with other people I prefer to have as little external dependencies as you can  

e.g. libraries should never configure logging

# why generators are good: fbchat export example

separating network retrieval and storing in database. with generators can do it simultaneously  




# another example of cool generator use in fbchat

    mts = int(r.timestamp)
    if newest is not None and oldest is not None and newest > mts > oldest:
        logger.info('Fetched everything for %s', thread.name)
        break # interrupt, thus interrupting fetching data
    db.insert_message(thread, r)

# hacky 'autonaming'

        # TODO end_lineno is not set??
        node = None
        for x in src.body:
            if x.lineno >= lno:
                break
            node = x
        [tg] = node.targets
        return tg.id
    
    class Namer:
