didn't understand why you kept importing some things directly inside function, especially as you had to reimport it in the same file sometimes. Maybe im missing something, completely possible.

This part in not clear at all and need a rewrite.

I've improved it. This endpoint is used to create a new player. The password field in the data is required in 2 cases:

• When it's an EventTournament, the password must be supplied and must be the same as the team password.
• In the case of a PrivateTournament with password, the password must be supplied and must be the same as the tournament password.

In all other cases (private tournament without password), it makes no difference whether the field is present or not, because for PrivateTournaments, the team has no password.
I hope that's clearer.

Other than that, lgtm !

(I didn't read the tests and didn't try to run most of the code btw)
