Ranking Poker Hands

A famous casino is suddenly faced with a sharp decline of their revenues. They decide to offer Texas hold'em also online. Can you help them by writing an algorithm that can rank poker hands?

Task:

Create a poker hand that has a method to compare itself to another poker hand:

    compare_with(self, other_hand)

A poker hand has a constructor that accepts a string containing 5 cards:

    PokerHand(hand)

The characteristics of the string of cards are:
A space is used as card seperator
Each card consists of two characters
The first character is the value of the card, valid characters are:

2, 3, 4, 5, 6, 7, 8, 9, T(en), J(ack), Q(ueen), K(ing), A(ce)
The second character represents the suit, valid characters are: 
S(pades), H(earts), D(iamonds), C(lubs)

The result of your poker hand compare can be one of these 3 options:

    RESULT = ["Loss", "Tie", "Win"]

Apply the Texas Hold'em rules for ranking the cards.
There is no ranking for the suits.

知识点

• 这个题目比较有意思，算德州扑克中两个人五张牌谁大谁小，每张牌有两个字母表示，第一个为牌面大小，第二个为花色，可以先对五张牌的牌面大小做一个排序，然后看是否是23456这种连续的，如果是则牌很大，然后再判断是否为同一花色，最后再判断是否有对。
