sllist

✓ from llist import sllist

dllist

✓ from llist import dllist

Create singly and doubly linked lists, append elements, and convert to list.

from llist import sllist, dllist # Singly linked list s = sllist([1, 2, 3, 4, 5]) print('sllist:', list(s)) s.append(6) print('After append:', list(s)) # Doubly linked list d = dllist([10, 20, 30]) print('dllist:', list(d)) d.appendright(40) print('After appendright:', list(d))

Debug

Known issues

gotchaThe `sllist` and `dllist` classes do not support `len()` in Python 3. Use `sllist.size()` method instead.

fix

Use `len(list(s))` or `s.size()` to get the length.

affects: all

gotchaThe `dllist` does not support indexing (e.g., `d[0]`) because it is not a sequence. Access elements via iteration or conversion to list.

fix

Use `list(d)[0]` or iterate over the list.

affects: all

breakingIn version 0.7, the `sllist` and `dllist` no longer support direct slicing like Python built-in lists. Attempting to slice will raise a TypeError.

fix

Convert to list first: `list(mylist)[start:stop]`.

affects: 0.7+

gotchaThe `llist` module uses the name `dllist` which conflicts in some IDEs with the concept of a doubly linked list. No actual library conflict, but users sometimes confuse with `deque` from collections.

fix

Remember `llist.dllist` is a linked list, not the `collections.deque`.

affects: all

Errors

Common errors & fixes

AttributeError: module 'llist' has no attribute 'dllist'

Import path is incorrect; some users try `import llist` and then use `llist.dllist` but it may not be imported automatically.

fix

Use `from llist import dllist` or `import llist; d = llist.dllist()`.

TypeError: 'sllist' object is not subscriptable

Trying to index into a singly linked list like a Python list.

fix

Convert to list first: `list(s)[index]`.

AttributeError: 'sllist' object has no attribute 'len'

Calling `len(s)` on an sllist object; len() is not defined.

fix

Use `s.size()` or `len(list(s))`.
