I don't know if/where this is documented, but there are structural limits:
>>> def nested(N):
... return "".join(" " * i + "if 1:\n" for i in range(N)) + " " * N +
"print('hi')"
...
>>> print(nested(3))
if 1:
if 1:
if 1:
print('hi')
>>> exec(nested(99))
hi
>>> exec(nested(100))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 101
print('hi')
