Hello, I didn't want to edit `__init__` and my solution works in the Workspaces. Shell entries:

from ... import Liar

tmp = Liar(1, 2, 3, 4, 5)

len(tmp)

... random number from doubled original len

Task validation throws following exception: "ValueError: empty range for randrange() (1,1, 0)". What am I doing wrong? Thank you

frustration.py
```import random

class Liar(list):
def __len__(self):
my_len = super().__len__()
rnd_len = random.randint(1, my_len * 2)
while rnd_len == my_len:
rnd_len = random.randint(1, my_len * 2)
else:
return rnd_len
``` MOD

You're on the right path, It's your choice of "lie" can cause an empty range if the initial list has zero length. This causes calling `random.randinit(1,0)` which fails. Choosing another "lie" would work, such as, `random.randint(my_len, (my_len + 1) * 2)` or simply `my_len + 2` Well in this case a simple workaround can be also an "if statement" after requesting original len from super. Something like:

import random

class Liar(list):

```def __len__(self):

my_len = super().__len__()

if not my_len > 0:

my_len = 5

rnd_len = random.randint(1, my_len * 2)

while rnd_len == my_len:

rnd_len = random.randint(1, my_len * 2)

else:

return rnd_len
```

But this is sort of forced fix, since my_len is obviously not assigned as intended. I do not understand how list is passed to the Liar class by the validation script. By the way, correction on my side, in the original post I missed square brackets in this line -> tmp = Liar(1, 2, 3, 4, 5) Thanks, Pavlo
