What is it?

• A set which doesn't require hashable contents

Why create it?

• I often have a need to store non-hashable contents in a set. For example storing a dict isn't possible with the builtin set.

  # doesn't work
  someDict = { "key": "value" }
  someSet = { someDict }
  

Simple usage

from all_purpose_set import ApSet

someDict = { "key": "value" }
someSet = ApSet([someDict])

print(someDict in someSet) # prints True

Api

Note: This api is young and subject to change quite a bit. There also may be functionality present in the builtin set which this set doesn't cover. I'm willing to add it so please just raise a github issue or PR with details.

class ApSet([a list])

• all methods return self unless specified otherwise
• iterates in the order of insertion
• currently the internal methods implemented are
  • __contains__
  • __iter__
  • __len__

add(something)

clear()

has(something) => bool

• a function alternative to key in aSet

remove(something)

• raises a KeyError if the element doesn't exist
