Python doesn't have a built-in pipe operator, but that doesn't mean you can't do it. The pipe [1] library is popular.

    is_even = where(lambda x: x % 2 == 0)
    sum(fib() | is_even | take_while(lambda x: x < 4000000)

The Apache Beam SDK for Python is another example. It has its own pipe expressions (|, >>, |>, etc.).

I would haver have + than | if we introduce "custom" operators.

Like maybe bitshifting strings into streams wasn't the right syntax, Bjarne

datar effectively recreates a pipe operator and the tidyverse approach.

  df >> mutate(z=f.x)
