I have a list of rect objects which is randomly generated and i want to take a specific element out of the list with .remove(), how would I be able to do something like that? Here's the snippet:

map = [(x, y) for x in range(0,20) for y in range(0,20)]

def cellGen():
    global mObj
    xr = random.randint(1,21)
    yr = random.randint(1,21)
    tp = (xr,yr)
    if tp in map:
        cell = pygame.Rect(tp\[0\]\*20, tp\[1\]\*20, 20, 20)
        pygame.draw.rect(window, (0,0,0), cell)
        mObj.append(cell)

.

.

.

#k2 is a set of dictionary keys in a list; valCel is all the valid rectangles' coordinates (tuples )in a list
for values in k2:

    if (values[0],values[1]) in valCel:
    
        valCel.remove((values[0],values[1]))
        #if (values[0],values[1]) in mObj:
        mObj.remove((values[0],values[1],20,20))

ValueError: list.remove(x): x not in list

here's mObj's output: [<rect(300, 200, 20, 20)>, <rect(160, 300, 20, 20)>, <rect(380, 120, 20, 20)>, <rect(300, 300, 20, 20)>, <rect(60, 140, 20, 20)>, <rect(100, 20, 20, 20)>, <rect(100, 140, 20, 20)>, <rect(80, 280, 20, 20)>, <rect(320, 380, 20, 20)>, <rect(40, 380, 20, 20)>, <rect(220, 160, 20, 20)>, <rect(140, 200, 20, 20)>, <rect(40, 20, 20, 20)>, <rect(240, 120, 20, 20)>, <rect(100, 220, 20, 20)>, <rect(200, 200, 20, 20)>, <rect(40, 240, 20, 20)>, <rect(100, 40, 20, 20)>, <rect(380, 20, 20, 20)>, <rect(320, 220, 20, 20)>, <rect(60, 260, 20, 20)>, <rect(60, 20, 20, 20)>, <rect(360, 40, 20, 20)>, <rect(360, 320, 20, 20)>, <rect(40, 260, 20, 20)>, <rect(220, 20, 20, 20)>, <rect(160, 140, 20, 20)>, <rect(160, 380, 20, 20)>, <rect(100, 240, 20, 20)>, <rect(300, 260, 20, 20)>, <rect(180, 380, 20, 20)>, <rect(380, 380, 20, 20)>, <rect(240, 60, 20, 20)>, <rect(60, 40, 20, 20)>, <rect(100, 60, 20, 20)>, <rect(160, 260, 20, 20)>, <rect(360, 300, 20, 20)>, <rect(300, 40, 20, 20)>, <rect(160, 360, 20, 20)>, <rect(40, 140, 20, 20)>, <rect(280, 380, 20, 20)>, <rect(380, 60, 20, 20)>]

How would i be able to take <rect(40, 140, 20, 20)> out of the list without calling the index of the element?

The objects in list are of the type pygame.Rect so you have to pass the right object type to it be found. I suggest check if object is in list before call the remove function also.

for values in k2:

    if (values[0],values[1]) in valCel:
    
        valCel.remove((values[0],values[1]))
        object = pygame.Rect(values[0], values[1], 20, 20)
        if object in mObj:
        mObj.remove(object)
