I wanted to implement that the player rotates acording too the mouse cursor ( too look around ).
First i calcultate the degree the player needs to rotate in the : get_rotation() method , the result is stored in self.degree. After that i called the pygame.transform.rotate(self.imageF, self.degree) function , but it doesnt rotate the sprite.

import pygame
import settings
import math

WHITE = (255, 255, 255)
BLACK = (0, 0, 0)

class Player(pygame.sprite.Sprite):
    

    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = pygame.image.load('sprites/Sprite-0001-player.png').convert_alpha()
        self.imageF = pygame.transform.scale_by(self.image, 3)
        self.rect = self.imageF.get_rect()
        self.rect.center = (600, 400)
        self.degree = 0

    def get_rotation(self):
        # Using Geometry to calculate the degree needed to rotate the player

        posM = pygame.mouse.get_pos()

        c = int(posM[0]) - self.rect.x
        a = int(posM[1] - self.rect.y)
        try:
            tan = a/c
            self.degree = round(math.degrees(math.atan(tan)), 1)
            print(self.degree)
        except:
            print("0")
    


    def update(self):
        
        keys = pygame.key.get_pressed()
        if keys[pygame.K_a]:
            self.rect.x -= 5
        if keys[pygame.K_d]:
            self.rect.x += 5
        if keys[pygame.K_w]:
            self.rect.y -= 5
        if keys[pygame.K_s]:
            self.rect.y += 5

        # Should rotate the player
        Player.get_rotation(self)
        pygame.transform.rotate(self.imageF, self.degree)

First of all i thought i maybe messed up the calculation but if i print the self.degree in the terminal it works just fine. So i guess there has to be a problem with my implemntation of pygame.
Thats how i came up with the Calculations
