Reading this
https://github.com/JulienPalard/Pipe
i tried this simple code
import functools
class Pipe:
def __init__(self, function):
self.function = function
functools.update_wrapper(self, function)
def __ror__(self, other):
return self.function(other)
def __call__(self, *args, **kwargs):
return Pipe(lambda x: self.function(x, *args, **kwargs))
@Pipe
def list(x):
return [x]
@Pipe
def count(iterable):
"Count the size of the given iterable, walking thrue it."
count = 0
for x in iterable:
count += 1
return count
Can someone tell me why/how this code gives me the | available in the
console to pipe functions
>> [2,3,4,2,4] | count |list
[5]
Regards
António
