9 Python Components
Python components (we will use the term ``component'' here to mean
regular components, data components or top-level documents)
are a way to write components and/or data components using straight
Python. They are useful for when the operation of the component is
code-heavy and/or not terribly markup-intensive.
To call other components from within Python components, there is a
function in the AE.Component module called, aptly enough,
callComponent whose definition looks like this:
def callComponent (name, argDict, cache = 0,
defer = None, compType = DT_REGULAR)
The arguments are:
- name
- the path to the component (can be relative)
- argDict
- dictionary of arguments to the component
- cache
- equivalent to the cache parameter in the
component tags, but see section 4.2, page
for actual values to use.
- compType
- either the default (a regular
component), AE.Component.DT_REGULAR,
AE.Component.DT_DATA for a data component or
AE.Component.DT_INCLUDE
The return value is either the output of the component, in the case of
a regular component, or the return value of the component, in the case
of a data component.
