Generators with input

Usage

  • cat(<generator-with-input>…)
  • <pipelined-iterable> | <generator-with-input>

Use the special STDIN to access your input.

Examples

>>> from grapevine import *

>>> cat((1, 2, 3)) | (-x for x in STDIN) | tuple
(-1, -2, -3)

>>> cat(x + 1 for x in (1, 2, 3)) | (x * x for x in STDIN) | tuple
(4, 9, 16)

>>> def tmp():
...     n = 0
...     for i in STDIN:
...             n += i
...             if n > 10:
...                     yield n
...                     n = 0
...
>>> xrange(10) | cat([4], tmp(), [2]) | tuple
(4, 15, 13, 17, 2)
