Module Importing Utilities - `kombu.utils.imports`¶

Import related utilities.

kombu.utils.imports.symbol_by_name(name, aliases=None, imp=None, package=None, sep='.', default=None, **kwargs)[source]¶

Get symbol by qualified name.

The name should be the full dot-separated path to the class:

modulename.ClassName

Example:

celery.concurrency.processes.TaskPool
                            ^- class name

or using ‘:’ to separate module and symbol:

celery.concurrency.processes:TaskPool

If aliases is provided, a dict containing short name/long name mappings, the name is looked up in the aliases first.

Examples

>>> symbol_by_name('celery.concurrency.processes.TaskPool')
<class 'celery.concurrency.processes.TaskPool'>

>>> symbol_by_name('default', {
...     'default': 'celery.concurrency.processes.TaskPool'})
<class 'celery.concurrency.processes.TaskPool'>

# Does not try to look up non-string names. >>> from celery.concurrency.processes import TaskPool >>> symbol_by_name(TaskPool) is TaskPool True
