You have to compute the angle of the vector from the player to the mouse. get the mouse position by pygame.mouse.get_pos() and the rectangle (pygame.Rect) around the player:

Calculate the vector from the player to the mouse and compute the angle of vector by math.atan2. The y-axis needs to be reversed (-dy) as the y-axis is generally pointing up, but in the PyGame coordinate system the y-axis is pointing down.

In addition, a correction angle must be deducted (- correction_angle). The correction angle depends on the Sprite. If the Sprite

is looking to the right, the correction angle is 0: correction_angle = 0
is looking up, the correction angle is 90: correction_angle = 90
is looking to the left, the correction angle is 180: correction_angle = 180
is looking down, the correction angle is 270: correction_angle = 270

Rotate the player with pygame.transform.rotate() by the angle around its center:
