A library to inject common functional programming operations as methods into iterable objects.
pip install funcipy==0.5
A library to inject common functional programming operations as methods into
iterable objects. Currently, it injects filter, flat_map, foldl, foldr, map,
and reduce
operations along with sum, count, any, all, max, min,
and zip
operations.
The library can be installed via pip install funcipy
. Similarly, it can be
uninstalled via pip uninstall funcipy
.
When you want to inject common functional programming operations as methods
into an object Obj, invoke funcipy.funcify
function with Obj as the
argument. If Obj is iterable, then the function will return an object that
Otherwise, Obj is returned as is.
Here are few example invocations.
from funcipy import funcify
import functools
import itertools
import operator
i = range(5, 15)
print("Map function: " + ' '.join(map(str, i)))
tmp1 = funcify(i)
print("Map function applied to funcified object: " + ' '.join(map(str, tmp1)))
print("Map method: " + ' '.join(tmp1.map(str)))
print("Map and Filter Method chaining: " +
' '.join(tmp1.filter(lambda x: x % 2).map(str)))
print("Reduce function: " + str(functools.reduce(operator.add, i, 5)))
print("Reduce method: " + str(tmp1.reduce(operator.add, 5)))
print("Reduce function: " + str(functools.reduce(operator.sub, i)))
print("Foldl method: " + str(tmp1.foldl(operator.sub)))
print("Foldr method: " + str(tmp1.foldr(operator.sub)))
print("Flat-map operation: " + ' '.join(itertools.chain.from_iterable(
map(str, i))))
print("Flat-map method: " + ' '.join(funcify(i).flat_map(str)))
print("Sum function: " + str(sum(i)))
print("Sum method: " + str(tmp1.sum()))
print("Count function: " + str(sum(1 for _ in filter(lambda x: x > 10, i))))
print("Count method: " + str(tmp1.count(lambda x: x > 10)))
print("Max function: " + str(max(i)))
print("Max method: " + str(tmp1.max()))
print("Min function: " + str(min(i)))
print("Min method: " + str(tmp1.min()))
print("Any function: " + str(any(map(lambda x: x > 10, i))))
print("Any method: " + str(tmp1.map(lambda x: x > 10).any()))
print("All function: " + str(all(map(lambda x: x > 10, i))))
print("All method: " + str(tmp1.map(lambda x: x > 10).all()))
j = range(0, 7)
print("Zip function: " + ' '.join(map(str, zip(i, j))))
print("Zip method: " + ' '.join(tmp1.zip(j).map(str)))
