The pipe operator uses what comes before as the first argument of the function. This means in R it would be:

    result <- df
      |> fun1(arg1=1)
      |> fun2(arg2=2)

Python doesn't have a pipe operator, but if it did it would have similar syntax:

    result = df
      |> fun1(arg1=1)
      |> fun2(arg2=2)

In existing Python, this might look something like:

    result = pipe(df, [
      (fun1, 1),
      (fun2, 2)
    ])

(Implementing `pipe` would be fun, but I'll leave it as an exercise for the reader.)

Edit: Realized my last example won't work with named arguments like you've given. You'd need a function for that, which start looking awful similar to what you've written:

    result = pipe(df, [
      step(fun1, arg1=1),
      step(fun2, arg2=2)
    ])
