Dear quy-nh,

I started to use the libraries recently. to update custom attributes you can use:
https://github.com/pvizeli/pycognito#update-profile

Note that custom attributes need to be prefixed by "custom:" e.g. if you want to update the custom attribute country =>
u.update_profile({''custom:countyr':'Austria'},attr_map=dict())

The custom attributes need also to be read/writeable for your app. (https://medium.com/graymatrix/using-custom-attributes-in-amazon-cognito-user-pool-288cd3128bae)
