There is also Codon, which comes with pre-implemented pipelines, including support for parallel pipelines.
Examples from the Codon documentation:
def add1(x):
return x + 1
2 |> add1 # 3; equivalent to add1(2)
def calc(x, y):
return x + y**2
2 |> calc(3) # 11; equivalent to calc(2, 3)
2 |> calc(..., 3) # 11; equivalent to calc(2, 3)
2 |> calc(3, ...) # 7; equivalent to calc(3, 2)
def gen(i):
for i in range(i):
yield i
5 |> gen |> print # prints 0 1 2 3 4 separated by newline
range(1, 4) |> iter |> gen |> print(end=' ') # prints 0 0 1 0 1 2 without newline
[1, 2, 3] |> print # prints [1, 2, 3]
range(100000000) |> print # prints range(0, 100000000)
range(100000000) |> iter |> print # not only prints all those numbers, but it uses almost no memory at all
