URL params doesn't accept character '.' as a parameter

Hello there i've been using the tool for a while now and i encountered an issue recently.
I have the following code line:
`status_search_customer, data_search_customer = cms.customers.search.get(f_users.login = csv_dicc["login"])`
As far as i can see the issue here is that the parameter is taken by python as a method due to the . character in it. Is there a way around this problem?
