Extended function semantics¶
Many of funcy functions expecting predicate or mapping function as an argument can take something uncallable instead of it with semantics described in this table:
f passed | Function | Predicate |
---|---|---|
None |
identity |
bool |
string | re_finder(f) |
re_tester(f) |
int or slice | itemgetter(f) |
itemgetter(f) |
mapping | lambda x: f[x] |
lambda x: f[x] |
set | lambda x: x in f |
lambda x: x in f |
Supporting functions¶
Here is a full list of functions supporting extended function semantics:
Group | Functions |

Sequence splitting | dropwhile() , takewhile() , split() , split_by() |
Sequence chunking | group_by() , count_by() , partition_by() , ipartition_by() |
Collection transformation | walk() , walk_keys() , walk_values() |
Collection filtering | select() , select_keys() , select_values() |
Content tests | all() , any() , none() , one() , some() , is_distinct() |
