Pygame .Rect won't "collide" with mouse

Pygame .Rect won't "collide" with mouse

I am working on a simple game and with small circle "systems". I would
like to be able to click each system so that I can do more with it later
in game but I am having difficulty recognizing only a single click. I pass
the randomly generated coords to a dictionary and then the collision for
each rect should be checked with the mouse position but for some reason
that is not working anymore. Any help is appreciated.
Here is some of the more relevent code.
for i in range(NumSystems):
SysSize = random.randint(3,SystemSize)
SysY = random.randint(SystemSize*2,GVPHEIGHT-SystemSize*2)
SysX = random.randint(OverLayWidth+SystemSize*2,WINWIDTH-SystemSize*2)
SysList[str('SysNum')+str(i)] = ((SysSize,(SysX,SysY)))
SysCoords[str('SysNum')+str(i)] = pygame.draw.circle(DISPLAYSURF,
WHITE, (SysX,SysY), SysSize, 0)
pygame.display.update()
#time.sleep(.25)
#Code above is putting the random Coords into a dictionary.
while True:
MousePos=mouse.get_pos()
for event in pygame.event.get():
if event.type == QUIT:
pygame.QUIT()
sys.exit()
elif event.type == KEYDOWN:
# Handle key presses
if event.key == K_RETURN:
#Restarts the map
main()
elif event.type == MOUSEBUTTONDOWN:
if event.button == 1:
SysClicky(MousePos)
if SysClicked == True:
print('Clicked System')
elif SysClicked == False:
print('Something Else Clicked')
def SysClicky(MousePos):
for i in range(NumSystems):
print('Made to the SysClicky bit')
if SysCoords['SysNum'+str(i)].collidepoint(MousePos):
SysClicked = True
print(SysClicked)
return SysClicked
else:
SysClicked = False
return SysClicked
