Explanation for runs logic specifically:

# since the list is sorted and reduced to unique values, this means adjacent values will all be the same value after offset

z = []
for i,j in enumerate(d):

# group the values by unique value
# then add the length of the groups to the list
# ex: [2, 2, 2, 7] -> [2:[2,2,2], 7:[7]]
#     [2:[2,2,2], 7:[7]] -> [[3], [1]]
w = []
for i,e in groupby(z):

z = []
for x in w:
    for i,j in enumerate(x):
        if j>2:
            # if the group length is larger than 2
            # slice the list of unique card values to obtain only run values
            # since the run can be anywhere in the list, sum the preceding lengths to find the start and end index
            a = d[ sum(x[:i]) : sum(x[:i])+j ]
            z.append(a)

w = []
for m in z:
    # get the number of times the value is in the entire hand
