Légèrement plus court que grc la réponse , et prend un itinéraire différent pour y arriver.
Explication:

# function f which takes the hand+up card+crib string as its argument
def f(a):
# convert space-separated string into list of items.
a=a.split()
# remove the 4th index, which is always "|".
a.pop(4)
# change golfed by Jo King
# if the final item in the list is a "!" (if it is <"$"), remove it from the list and assign it to variable "e".
# otherwise, assign 0 to variable "e".
# a non-empty string will evaluate to True and 0 will evaluate to False in IF checks later.
e=a.pop(5)if a[-1]<"$"else 0
# for each card in the list, split the identifiers into the value(i) and the suit(j).
# return the value's index in the string "A23456789TJQK".
# so, ["5S", "5H", "5D", "JS", "KS"] will return [4, 4, 4, 10, 12].
# using the aliased built-in function sorted(), sort the list numerically ascending.
b=S("A23456789TJQK".index(i)for i,j in a)
# get the unique items in b, then sort the result numerically ascending.

# for each card in the list, split the identifiers into the value(i) and the suit(j).
# return the suits.

# get all unique combinations of cards for 5 cards, 4 cards, 3 cards, 2 cards, and 1 card
# add the values of all unique combinations, and return any that equal 15

Explication de la logique d'exécution spécifiquement:
# for each index and value in the list, add the value minus the index
# since the list is sorted and reduced to unique values, this means adjacent values will all be the same value after offset
# ex: "JD 3C 4H 5H | 5S" -> [2, 3, 4, 10] - > [2, 2, 2, 7]
z = []
for i,j in enumerate(d):
z.append(j-i)
# 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
# ex: "JD 3C 4H 5H | 5S" -> [2,3,4,4,10] and (2,3,4) -> [1, 1, 2]
a = [b.count(k)for k in m]
