Is there an python process for this R code

i am working on python and i want to group by my data by to columns and at the same time add missing dates from a date1 corresponding to the occurrence of the event to another date2 corresponding to a date that a choose and fill the missing values into the columns i decided by forwarfill .

I tried the code bellow on r and its works i want to do the same in python

library(data.table)
library(padr)
library(dplyr)

data = fread("path", header = T)
data$ORDERDATE <- as.Date(data$ORDERDATE)
datemax = max(data$ORDERDATE)
data2 = data %>% 
    group_by(Column1, Column2) %>% 
    pad(.,group = c('Column1', 'Column2'), end_val = as.Date(datemax), interval = "day",break_above = 100000000000) %>% 
    tidyr::fill("Column3")

I search for the corresponding package library(padr) in python but couldn't find any.
