passing function parameters in rpy2

i am interested in passing function parameters using rpy2. my function in R is normally called as follows:

rtn_val <- fn(param1="str_param1",
              a.b.param2=NULL,
              param3=7,
              param4=FALSE)

fn is contained in a library called MyLib. so far, my python code looks like this:

from rpy2.robjects.packages import importr
my_lib = importr("MyLib")

i am not sure how to pass the relevant parameters to my_lib.fn. any guidance is much appreciated. thanks!

Go ahead and call it like any named Python function but be sure to replace periods in parameters with underscores, NULL value as None, and proper case of False:

from rpy2.robjects.packages import importr
my_lib = importr("MyLib")

rtn_val = my_lib.fn(param1 = "str_param1",
                    a_b_param2 = None,
                    param3 = 7,
                    param4 = False)
