How do i rotate this in pygame?

Question

I need to rotate my 'player' for this game of asteroids and then move it along that same path it would get rotated, but I can't seem to think how to do so(btw i am an extreme beginer). This is my code so far:

import pygame
import random
import time
import math
from pygame import mixer

print('Wassup.')

pygame.init()

screen = pygame.display.set_mode((800,600))

#player
playerimg =pygame.image.load('player.png')
playerx = 370
playery =270
playerx_c = 0
playery_x = 0


def player(x,y):
    screen.blit(playerimg,(x, y))

screen.fill((25,50,100))    
player(playerx,playery)
pygame.display.update()
