I need advise with developing a brute forcing script

[fatjuicypython]

I need some advise on developing a script to brute force a 4 digit pin.

I know the pin has to be from 0000 to 9999

However, on the game website there is a slot for me to add 4 digit pin. How can I instruct python, to brute force every number from 0000 - 9999 in that specific part of the website asking for pin ?
