class bw2data.proxies.ActivityProxyBase(data, *args, **kwargs)[source]#

A MutableMapping is a generic container for associating key/value pairs.

This class provides concrete generic implementations of all methods except for __getitem__, __setitem__, __delitem__, __iter__, and __len__.

lca(method=None, amount=1.0)[source]#: Shortcut to construct an LCA object for this activity.

class bw2data.proxies.ExchangeProxyBase(data, *args, **kwargs)[source]#

A MutableMapping is a generic container for associating key/value pairs.

This class provides concrete generic implementations of all methods except for __getitem__, __setitem__, __delitem__, __iter__, and __len__.

property uncertainty[source]#: Get uncertainty dictionary that can be used in uncertainty analysis.

property uncertainty_type[source]#: Get uncertainty type as a stats_arrays class.

property unit[source]#

Get exchange unit.

Separate property because the unit is a property of the input, not the exchange itself.

_get_input()[source]#

Get or set the exchange input.

When getting, returns an Activity - this will raise an error if the linked activity doesn’t yet exist.

When setting, either an Activity or a tuple can be given. The linked activity does not have to exist yet.

_get_output()[source]#

Get or set the exchange output.

When getting, returns an Activity - this will raise an error if the linked activity doesn’t yet exist.

When setting, either an Activity or a tuple can be given. The linked activity does not have to exist yet.

lca(method=None, amount=None)[source]#

Shortcut to construct an LCA object for this exchange input.

Uses the exchange amount if no other amount is provided.
