Using Venn Diagram Add-on with Tup

Question

I’m trying to do some stats homework in python and I wanted to create a Venn diagram of some different outcome spaces. I’m trying to pass two-element tuples to the Venn diagram and it doesn’t seem to be too pleased about it. I really appreciate anyone who helps point me in the right direction!

…

combination_storage_container = [] 
for i in range(1,7):

    out = "(" + str(i) + ", " # making the initial string form
    print("n")

    for j in range(1,7):
    
        out += (str(j) + ")") # adding the final piece
        print(out, end=" , ") # printing the piece 
        out = out[:4] 
        combination_storage_container.append(tuple([i,j]))
    
print("nnn",combination_storage_container)
# IF I was making this a permanent piece of code, id do it in one loop
A_space = []
B_space = []
C_space = []
for combo in combination_storage_container:
    if combo[0] + combo[1] > 8: # <------ sum condition
        A_space.append(combo)
    if combo[0] == 2 or combo[1] == 2: # 2 condition
        B_space.append(combo)
    if combo[0] > 4: #<-------------- green bigger than 4 condition
        C_space.append(combo)
print("The A space is:n", A_space)
print("The B space is:n", B_space)
print("The C space is:n", C_space)

venn3([A_space, B_space, C_space], ('A Space', 'B Space', 'C Space'))
plt.show()

…

I get this error:

TypeError: unsupported operand type(s) for |: 'list' and 'list'

When you are passing three subsets like that, the first argument in the venn3 function needs to be a list (or a tuple) of sets, so that their membership can be compared with the | (union) operator. You are currently passing a list of lists, so convert the lists to sets:

venn3([set(A_space), set(B_space), set(C_space)], ('A Space', 'B Space', 'C Space'))
