Translations for python in French

Here are paragraphs from public domain books translated:

"I should be glad, Professor Challenger," said he, "if you could see your way to make any remarks which may occur to you without seizing me by the chin. Even the appearance of a very ordinary rock python does not appear to justify such a liberty."	— Je vous saurais gré, professeur Challenger, dit-il, de faire vos remarques sans me tenir le menton. Il ne me semble pas que même l’apparition d’un vulgaire python autorise une liberté pareille.
The Lost World, by Arthur Conan Doyle	Le Monde perdu, de Arthur Conan Doyle
