python 3.x - Random colors for a tree map with squarify / RGBA values should be within 0-1 range

Question

I'm creating a few maps with squarify and I'm trying to create a list of random colors with length = len(df). I've seen this similar thread, but don't see the solution there.

for row in range(len(df)):
    random_number = random.randint(0, 16777215)
    hex_number = str(hex(random_number))
    hex_number = '#' + hex_number[2:]
    colors.append(hex_number)
# Plotting
squarify.plot(sizes=df, label=df.index, color=colors)

With the code above, I ended up with Invalid RGBA argument.

So I've tried RBG colors based on this thread/answer:

for row in range(len(df)):
    color = list(np.random.choice(range(256), size=3))
    color.append(0.7) #opacity
    colors.append(color)
# Plotting
squarify.plot(sizes=df, label=df.index, color=colors)

But then I get a RGBA values should be within 0-1 range, but this is not what I'd expect of RGBA values.

Any tip on how I could create generate these random RGBA values for squarify? Thanks!
