SSAS MDX Query Within Python (adodbapi library) with dynamic Parameter '?'

Question

I am using the adodbapi python library to query an SSAS Cube. Essentially, my goal is to ask the user to first input the Account Id. Then, I would like that to be passed as a parameter dynamically in the WHERE section of the query with a ? and include an argument in the cur.execute() part of the code per how it is mentioned in the documentation I have linked below. cur.execute() is where I am getting the error, and I have also copy and pasted most of the error below.

I have narrowed down the issue to the fact that the parameter is not working. Dynamic parameters work well for me with PyODBC and pd.read_sql, but they don't seem to work with adodbapi, which I must use as it is the only library I have ever successfully queried an SSAS cube with from within python.

import adodbapi
import numpy as np
import pandas

account_id_input = input("Select Account ID: ").strip()

def get_df(data):
    ar = np.array(data.ado_results) # turn ado results into a numpy array
    df = pd.DataFrame(ar).transpose() # create a dataframe from the array
    return df


with adodbapi.connect('''Provider=MSOLAP;
Data Source=MyServerName;
Initial Catalog=MySSASModel;
User ID=MyUserLogin;
Password=MyPassword;
Persist Security Info=True;
Impersonation Level=Impersonate''', 7200) as con:
    with con.cursor() as cur:
        sql_str = r'''SELECT
NON EMPTY
{
[Measures].[Revenue]
}
ON COLUMNS,

NON EMPTY
[AccountTable].[Year-Month].[Year-Month]

ON ROWS
FROM [Model]
WHERE([AccountTable].[Account Number].[?])
'''
        args = [account_id_input]
        cur.execute(sql_str, args)
        data = cur.fetchall()
        df = get_df(data)
        df.columns = ['Year-Month','Revenue']
df

I have tried everything and am out of ideas. I was referencing this document: http://adodbapi.sourceforge.net/quick_reference.pdf and some some other stackoverflow posts that were similar: enter link description here , but I could not figure it out! My MDX is horrible, if anyone else has ideas on how I can rewrite the MDX query, so that it plays better with adodbapi in terms of dynamic parameters, if it is in fact an issue with the library.
