import output_file, show vs bokeh.plotting output_file, show

  1. from import output_file, show vs
  2. from bokeh.plotting import output_file, show

is there any difference between (both created same output).

Similarly I could not found difference between

  1. from bokeh.model import ColumnDataSource
  2. from bokeh.plotting import ColumnDataSource

You may advice where I can get such information. I browse bokeh documentation > in references. I could not get. Thank you

They are the same. There are a few things transitively imported into bokeh.plotting and made available from there for convenience and/or historical compatibility.

Thank you dear Bryan for your conclusive answer, it supports in moving forward.
