how to correctly get R sessionInfo() from python script with rpy2 api?

I am trying to get R sessioninfo() by using rpy2 in python script, the reason because I am going to make api call from python to custom R library. The basic thing I want to try is get current R sessioninfo() using simple python script.

my attempt:

here is the attempt that I tried by following this SO post:

import rpy2.robjects as robjects
import os

os.environ['R_HOME'] = "C:/PROGRA~1/R/R-36~1.3"
robjects.r('''
       source('myfunc.r')
''')

myfunc = function(){
  return(sessionInfo())
}

I got R_HOME by using Sys.getenv('R_HOME') or R.home() in R studio.

new updated attempt:

based on @Parfait suggestion, I aso tried this way:

pip install .\rpy2-2.9.5-cp37-cp37m-win_amd64.whl

import os
os.environ['PYTHONHOME'] = r"C:\Users\mia\AppData\Local\Programs\Python\Python37"
os.environ['PYTHONPATH'] = r'C:\Users\mia\AppData\Local\Programs\Python\Python37\Lib\site-packages'
os.environ['R_HOME'] = r'C:\Program Files\R\R-3.6.3'
os.environ['R_USER'] = r'C:\Users\mia\AppData\Local\Programs\Python\Python37\Lib\site-packages\rpy2'

# importing rpy2
import rpy2
import rpy2.robjects as robjects

# test : evaluating R code
robjects.r('''
        # create a function `f`
        f <- function(r, verbose=FALSE) {
            if (verbose) {
                cat("I am calling f().\n")
            }
            2 * pi * r
        }
        ''')

r_f = robjects.r['f']
res = r_f(3)
print(res[0])

but now I get another error:

now I can import rpy2 also can import rpy2.robjects, but can't able to get R sessionInfo() correctly. any further thoughts? thanks

desired output:

I just want to print out R sessionInfo() in jupyternotebook or python script by using rpy2? any solution to make this happen? any thoughts? thanks a lot
