Examples

>>> from pathlib import Path
>>> import inspect
>>> from pyyeti.nastran import op2
>>> pth = Path(inspect.getfile(op2))
>>> fname = (
...     pth.parent.parent
...     / "tests"
...     / "nas2cam_extseout"
...     / "assemble.op2"
... )
>>> with op2.OP2(fname) as o2:
...    pos = o2.set_position(0)
...    while next_info := o2.next_db_info():
...        name, start = next_info.name, next_info.start
...        print(f"{name} starts @ {start} bytes")
...        o2.goto_next()
