How can I remove Somengines from the existing O.engines?

Asked by JINSUN LEE

For example,

O.engines=O.engines+[DomainLimiter(lo=(-.05,-.05,-.05), hi=(.05,.05,.05), iterPeriod = 100, label = 'Domain')]

DomainLimiter is appended to the existing engines.
As I know, O.engines is list type variable.
So, I have tried to remove DomainLimiter as follows:

In [2]: O.engines[5]
Out[2]: <DomainLimiter instance at 0x5610901b5220>

del O.engines[5]

However, it does not work

So, How can I remove the Someengines from the existing O.engines?

Regards.

Hi,

To remove the last engine from the list do this:

O.engines = O.engines[:-1]

That means take all the engines from the existing list, except of the last one.

Cheers,
Karol

Hello,

It is documented in [1]:
"The O.engines sequence must be always assigned at once ..."

To delete specific engine, you simple assign new O.engines without it (possibly using already assigned engines), e.g. to delete some engine "in the middle" you could do
O.engines = O.engines[:2] + O.engines[3:] # deleting engine with index 2

Cheers
Jan
