Instead of using the get_fundamentals function, you can simply pass the pe_ratio as a parameter in the screen method of Pipeline. It will look something like this :

        Pipeline( columns = {  
            'Testing factrs': testing_factors,  
            'Bottom Growth Company': bottom_20_secs,  
            'Top Growth Company': top_20_secs,  
        },  
        screen = securities_to_trade & (Fundamentals.pe_ratio.latest > 10) & (Fundamentals.pe_ratio.latest < 30))  

Is it possible to see what the actual PE Ratio is as a column on the Pipeline results?

You can see them by adding them to columns.
Try this: Set a breakpoint on line 57, run it, then type each of these one at a time followed by [enter]:

context.out  
context.out.sort_values(by='pe_ratio', ascending=False).head()  
context.out.sort_values(by='pe_ratio', ascending=False).tail()

I shortened column names for multiple reasons.

    pe_ratio = Fundamentals.pe_ratio.latest

    return Pipeline(  
        columns = {  
            'pe_ratio': pe_ratio,  
            'factrs'  : testing_factors,  
            'BGC'     : bottom_20_secs,  
            'TGC'     : top_20_secs,  
        },  
        screen = securities_to_trade & ((pe_ratio > 10) | (pe_ratio < 30)))  

This includes some code to log the top and bottom 3 also. I always use it.

    if 'log_pipe_done' not in context: log_pipe(context, data)

def log_pipe(context, data):  
        log.info('pipe len {}'.format(len(context.out)))  
        log.info('.\n{}'.format(context.out.sort_values(by='pe_ratio', ascending=False).head(3)))  
        log.info('.\n{}'.format(context.out.sort_values(by='pe_ratio', ascending=False).tail(3)))  
        context.log_pipe_done = 1  

Looks like this

End of logs.
