sidekick.op

This module exposes functionality analogous to the operator module in the standard lib. The main difference is that binary operators are curried and all functions are fn-functions. So we can use it as a drop-in replacement to the operator module:

>>> from sidekick import op
>>> op.add(1, 2)
3

But one that accepts additional idioms

>>> succ = op.add(1)
>>> succ(41)
42

Same as a <= b.

sidekick.op.lshift

Same as a << b.

sidekick.op.lt

Same as a < b.

sidekick.op.mod

sidekick.op.length_hint

Return an estimate of the number of items in obj.

This is useful for presizing containers when building from an iterable.

If the object supports len(), the result will be exact. Otherwise, it may over- or under-estimate by an arbitrary amount. The result will be an integer >= 0.

sidekick.op.attrgetter

attrgetter(attr, …) –> attrgetter object

Return a callable object that fetches the given attribute(s) from its operand. After f = attrgetter(‘name’), the call f(r) returns r.name. After g = attrgetter(‘name’, ‘date’), the call g(r) returns (r.name, r.date). After h = attrgetter(‘name.first’, ‘name.last’), the call h(r) returns (r.name.first, r.name.last).

sidekick.op.itemgetter

itemgetter(item, …) –> itemgetter object

Return a callable object that fetches the given item(s) from its operand. After f = itemgetter(2), the call f(r) returns r[2]. After g = itemgetter(2, 5, 3), the call g(r) returns (r[2], r[5], r[3])

sidekick.op.methodcaller

methodcaller(name, …) –> methodcaller object

Return a callable object that calls the given method on its operand. After f = methodcaller(‘name’), the call f(r) returns r.name(). After g = methodcaller(‘name’, ‘date’, foo=1), the call g(r) returns r.name(‘date’, foo=1).
