conditional 2.0 – Conditional Context

The conditional context manager comes handy when you always want to execute a with-block but only conditionally want to apply its context manager.

If you find yourself writing code like this:

if CONDITION:
    with CONTEXTMANAGER():
        BODY()
else:
    BODY()

Consider replacing it with:

with conditional(CONDITION, CONTEXTMANAGER()):
    BODY()

Asynchronous context managers are supported since version 2.0:

async with conditional(CONDITION, ASYNCCONTEXTMANAGER()):
    BODY()

The conditional context manager ships with type annotations. Type checkers and IDEs can use this information to implement type safety and auto completion.
