pls use python do this

Problem 3. Valid words

At this point, we have written code to generate a random hand and display that hand to the user. We can also ask the user for a word (Pythons input) and score the word (using your get_word_score). However, at this point we have not written any code to verify that a word given by a player obeys the rules of the game.

A valid word is in the word list and it is composed entirely of letters from the current hand.

Implement the is_valid_word function.

def is_valid_word(word, hand, word_list):

"""

Returns True if word is in the word_list and is entirely

composed of letters in the hand. Otherwise, returns False.

Does not mutate hand or word_list.

word: string

hand: dictionary (string -> int)

word_list: list of lowercase strings

"""

# TO DO...

Testing: Make sure the test_is_valid_word tests pass. In particular, you may want to test your implementation by calling it multiple times on the same hand what should the correct behavior be?

Problem 4. Playing a hand

We are now ready to begin writing the code that interacts with the player.

Implement the play_hand function. This function allows the user to play out a single hand.

def play_hand(hand, word_list):

"""

Allows the user to play the given hand, as follows:

* The hand is displayed.

* The user may input a word.

* An invalid word is rejected, and a message is displayed asking

the user to choose another word.

* When a valid word is entered, it uses up letters from the hand.

* After every valid word: the score for that word is displayed,

the remaining letters in the hand are displayed, and the user

is asked to input another word.

* The sum of the word scores is displayed when the hand finishes.

* The hand finishes when there are no more unused letters.

The user can also finish playing the hand by inputing a single

period (the string '.') instead of a word.

hand: dictionary (string -> int)

word_list: list of lowercase strings

"""

# TO DO ...

Testing: Try out your implementation as if you were playing the game.

Note: Do not assume that there will always be 7 letters in a hand! The global variable HAND_SIZE represents this value. Here is some example output of play_hand (your output may differ, depending on what messages you print out):

Case #1

Current Hand: a c i h m m z

Enter word, or a "." to indicate that you are finished: him

"him" earned 24 points. Total: 24 points

Current Hand: a c m z

Enter word, or a "." to indicate that you are finished: cam

"cam" earned 21 points. Total: 45 points

Current Hand: z

Enter word, or a "." to indicate that you are finished: .

Total score: 45 points.

Case #2

Current Hand: a s t t w f o

Enter word, or a "." to indicate that you are finished: tow

"tow" earned 18 points. Total: 18 points

Current Hand: a s t f

Enter word, or a "." to indicate that you are finished: tasf

Invalid word, please try again.

Current Hand: a s t f

Enter word, or a "." to indicate that you are finished: fast

"fast" earned 28 points. Total: 46 points.

Total score: 46 points.
