where do I get the username and password of crowd application?

[xyz]

I was trying to Authenticate Crowd rest Api using python code https://python-crowd.readthedocs.io/en/latest/  where i can get 

app_user = 'testapp'
app_pass = 'testpass'

How can i find app_user and app_pass in my crowd.

They will be whatever you set up in Crowd for the application you are creating.

Crowd, like any secure system, does not store the password, it stores a hash to validate against.   If you don't know what was set, you'll have to reset it.
