+A module for calculating the lengths of words in a sentence.

+    Takes a sentence and returns a list of word lengths, ignoring punctuation.
+
+    Args:
+        input_sentence (str): The input sentence.
+
+    Returns:
+        list: A list of integers representing word lengths.
+
+    Assumptions:
+        - If the input sentence is empty, the function will return an empty list.
+        - Punctuation is ignored when calculating word lengths.
+        - Case sensitivity does not affect word length calculation.
+
+    Examples:
+        >>> word_lengths("Hello world!")
+        [5, 5]
+        >>> word_lengths("Python is awesome.")
+        [6, 2, 7]
+        >>> word_lengths("co-op re-enter.")
+        [4, 7]
