You could still use the same idea and delay evaluation of the lists. E.g.

prg1 = """[
    [PUSH, [get_modified_interface, req]],
    [TIMEOUT, 3],
    ...
"""

prg2 = """[
    [OPCODE, [arguments, blah]],
    ...
"""

...

prgN = """..."""

for prg in prg1, prg2, ..., prgN:
    try:
        prg = eval(prg)
    except NameError:
        continue
    f(prg)
