class schrodinger.models.diffy.ListDiff(added, removed, moved)

Bases: tuple

added

Alias for field number 0

moved

Alias for field number 2

removed

Alias for field number 1

schrodinger.models.diffy.get_diff_list(new_state, old_state)

Calculate what was added, removed, and moved between two states of a list.

Note that items are compared by identity not equality (ie is rather than ==).

Returns:

A namedtuple describing what was added, removed, and moved between two lists. See get_added, get_removed, and get_moved more details.

Return type:

ListDiff(set, set, set)

class schrodinger.models.diffy.SetDiff(added, removed)

Bases: tuple

added

Alias for field number 0

removed

Alias for field number 1

schrodinger.models.diffy.get_diff_set(new_state, old_state)

Calculate what was added and removed between two states of a set.

Returns:

A namedtuple describing what was added and removed.

Return type:

SetDiff(set, set)

schrodinger.models.diffy.get_removed_set(new_state, old_state)

Calculate what was removed between two states of a set.

Return type:

set

schrodinger.models.diffy.get_removed_list(new_state, old_state)

Returns:

A set of tuples, each describing an item that was removed and and its index in old_state

Return type:

set((object, int))

schrodinger.models.diffy.get_added_list(new_state, old_state)

Returns:

A set of tuples, each describing an item that was added and and its index in new_state.

Return type:

set((object, int))

schrodinger.models.diffy.get_added_set(new_state, old_state)

Calculate what was removed between two states of a set.

Return type:

set

class schrodinger.models.diffy.DictDiff(added, removed, updated)

Bases: tuple

added

Alias for field number 0

removed

Alias for field number 1

updated

Alias for field number 2

schrodinger.models.diffy.get_diff_dict(new_state, old_state)

Return dictionary items that have been added, removed, and updated.

Returns:

A namedtuple describing what was added, removed, and moved between two dicts. See get_added, get_removed, and get_updated more details.

Return type:

DictDiff(dict, dict, dict)

schrodinger.models.diffy.get_added_dict(new_state, old_state)

Returns:

A dictionary with items in new_state but not in old_state.

schrodinger.models.diffy.get_removed_dict(new_state, old_state)

Returns:

A dictionary with items in old_state but not in new_state.

schrodinger.models.diffy.get_updated_dict(new_state, old_state)

Returns:

A dictionary with values that have changed from old_state to new_state. The values in the returned dictionary will be those from new_state.

schrodinger.models.diffy.get_moved_list(new_state, old_state)

Returns:

A set of tuples, each describing an item that was moved and and its index in new_state

Return type:

set((object, int))
