How to ignore the need of using \n or wrapping command inside () when writing multi-line Python command

[ntluong95]

Sometimes, one wants to write codes that are not too Pythonic, for example when chaining function in pandas, or plotnine command

summary = (
    sales
    .query('date.dt.year == 2021')  # Step 1
    .pipe(add_vat)  # Step 2
    .groupby(['region', 'category'])  # Step 3
    .agg(total_sales=('sales_amount', 'sum'), total_vat=('vat', 'sum'))  # Step 4
    .assign(average_vat=lambda x: x['total_vat'] / x['total_sales'])  # Step 5
)

ggplot() + \
    geom_map(aes(fill='covid_mobility_correlation'), data=gdf, color='white', \
             tooltips=layer_tooltips().line('@name')\
                                      .format('@covid_mobility_correlation', '.2f')\
                                      .line('correlation value|@covid_mobility_correlation')) + \
    scale_fill_gradient(name='correlation', low='#d7191c', high='#1a9641') + \
    ggtitle('Correlation between Mobility and CRI') + \
    ggsize(600, 450) + \
    theme_void()

In R, when using the pipe %>% in almost functions and + in ggplot2 functions, they are automatically connected. Can we implement the same thing for Python code in Positron?

This would be tough, I think, given that whitespace is syntactically meaningful in Python (unlike most languages including R). It's an interesting idea to think about how we might improve the experience, though! Would you say you are thinking about this when typing out Python code in a regular .py file? Or a Quarto file?

I am thinking on normal .py file. I know this feature might be tough, but at least having support for common usage like method chaining, ggplot would be the good starting point?
