class documentation

class AsyncFor(For): (source)

Constructor: AsyncFor(lineno, col_offset, parent, end_lineno, ...)

Class representing an ast.AsyncFor node.

An AsyncFor is an asynchronous For built with the async keyword.

>>> import astroid
>>> node = astroid.extract_node('''
async def func(things):
    async for thing in things:
        print(thing)
''')
>>> node

>>> node.body[0]
