Python 3.15+sysfunction

sys.get_lazy_imports_filter()

modules

Returns the installed lazy-import filter, or None if there is none.

Syntax

sys.get_lazy_imports_filter()

The filter is installed with sys.set_lazy_imports_filter and decides, for each potentially lazy import, whether to load the module immediately. Reading it is useful to swap the filter temporarily and then restore the previous one, instead of resetting someone else's setting to None.

Examples

import sys
print(sys.get_lazy_imports_filter())  # → None
