如何檢查一個陣列有卡的升序或兩張相同的卡或三張相同的卡

Question

我正在做一個撲克模擬，當我被困在如何使python檢查數組的對，直道，三個種類等等。我已經制作了我的代碼，因此每個卡片陣列都會爲每張卡片生成第二個陣列的商店值。 例如

a=[1,3,4,2,5,8,1] b=[2,2,4,7,10] c=[5,6,5,5,5] 

我將如何檢查是否有至少5點連續的數字（直）如果B具有至少2個數字彼此相等（一對），並且如果C具有4

Answer 1

排序的手。這樣可以輕鬆檢查直線，因爲您需要依次輸入五個數字。

對於某種類型的N，請遍歷列表並查看每件物品的數量。例如：

for pos in range(len(hand)): 
    card_count = hand.count(hand[pos]) 
    if card_count >= 2: 
     print "Hand has", card_count, hand[pos], "'s" 

我沒有送人這裏所有的細節 - 這將打印兩次，每次對，3次，3-的一類等等。我認爲你問大部分是你需要的基本列表方法。

Answer 2

這應該足以讓你開始。

def check_hand(_hand_): 
    last_c = '' 
    straight = 0 
    # This is illustrative, you can use this to return 
    # the greatest hand one could have 
    for card_value, number_of_occurences in _hand_.iteritems(): 
     if number_of_occurences == 2: 
      print("We have a 2 of a kind") 
     elif number_of_occurences == 3: 
      print("We have a 3 of a kind") 
     elif number_of_occurences == 4: 
      print("We have a 4 of a kind") 

     if last_c == '': 
      last_c = card_value 
     else: 
      if card_value - last_c == 1: 
       straight += 1 
      last_c = card_value 

    if straight >= 4: 
     print("we have a straight") 

a = [1, 3, 4, 2, 5, 8, 1] 
b = [2, 2, 4, 7, 10] 
c = [5, 6, 5, 5, 5] 

# nifty way of assigning a dictionary with how many 
# occurrences of a number in a list, and sorting it 
check = { 
    'a': dict((i, a.count(i)) for i in sorted(a)), 
    'b': dict((i, b.count(i)) for i in sorted(b)), 
    'c': dict((i, c.count(i)) for i in sorted(c)), 
} 

for which, hand in check.iteritems(): 
    print "Hand: " + which 
    check_hand(hand)
