Is the generator expression stored anywhere semantically intact?

Question

If I set a generator

myra = (x + 100 for x in range(5))

and then later do something with it, like

for i in myra:
    print(i)

the generator has run its course, cannot be iterated over again, got that.

But is there a way, before, during, or after use, to interrogate the generator object so it returns the generating string, or something semantically equivalent? e.g.

>>> print_the_foundation(myra)
a + 100 for a in range(5)

Answer 1

You can get the code object produced from the generator expression.

>>> import dis
>>> myra = (x+100 for x in range(5))
>>> dis.dis(myra.gi_code)
