I installed the Smartsheet Python sdk, imported the smartsheet module but am getting an error when I want to run the script. The error is localized to the smartsheet module and says that collections module is missing Mutable Sequence. I have already tried adding:

from collections.abc import MutableSequence

and had no change.

import smartsheet
import logging
import os

_dir = os.path.dirname(os.path.abspath(__file__))

This is what pops up in the terminal.

A "quick and dirty" solution (I have this one - Python 3.10):
Path you-python-installation\python\Lib\site-packages\smartsheet
File types.py Line 29
class TypedList(collections.MutableSequence):

Replace with

class TypedList(collections.abc.MutableSequence):

I think Сolleagues from smartsheet - will fix the compatibility problem (at least - I believe it)
The main reason is Deprecated since version 3.3, will be removed in version 3.10

  • Hi! Thanks for the answer! I edited my original post. Those lines underneath the code are the error message/console output, not my actual code. Sorry about that! – jhorvath Feb 01 '22 at 20:55

If you are not able to edit the package as recommended in the first solution, use Python 3.9 that is the last version to support collections Mutable Sequence.

Another solution I used is to modify the affected .py file in downloaded library from Smartsheet and change

import collections

to

import collections.abc as collections
