+#   However, in case of collaboration, if having platform-specific dependencies or dependencies

+
+# poetry
+#   Similar to Pipfile.lock, it is generally recommended to include poetry.lock in version control.
+#   This is especially recommended for binary packages to ensure reproducibility, and is more
+#   commonly ignored for libraries.

+#   Similar to Pipfile.lock, it is generally recommended to include pdm.lock in version control.
