I've stumbled upon wonderful https://github.com/kachayev/fn.py library. One thing I missed was the ability to use `_.method(args)` syntax. Following quick hack aims to fix that. CAVEAT: it's a hack, it'll work unpredictably for cases different than `_.method(args)`.

Scala-style underscore in Python.py

class Underscore:
  def __getattr__(self, methodname):
    return lambda *args, **kwargs: \
      lambda o: eval("o." + methodname)(*args, **kwargs)

_ = Underscore()

filter(_.startswith("A"), ["Africa", "America", "Europe"])
map(_.upper(), ["hello", "world"])
map(_.count("I"), ["TEAM", "TIM"])

# ['Africa', 'America']
# ['HELLO', 'WORLD']
# [0, 1]
