Dictionaries in python

Interesting code found in some python Scrabble programs:

word = input("Enter a four letter word ")
word = word.upper()
letterNum = {'A':1,'E':1,'D':2,'R':2,'B':3,'M':3,'V':4,'Y':4,'J':8,'X':8}

What does the following line print?

print(letterNum['A'])

How was it used in the scrabble program?
One possible answer:

value = 0
for i in word:
    value += letterNum[i]

print(value)

Another possible answer:

letterValue = [0,0,0,0]
for i in range(4):
    letterValue[i] = letterNum[word[i]]

print(letterValue)

Classwork:
Work in python’s shell and copy and paste your work on edmodo.com’s post: Dictionary – Clwk 1/8 – Basic Concepts

Create a dictionary: ‘hello’ is the key and ‘hola’ is the value

spanishDictionary = {'hello':'hola','goodbye':'adios','one':'uno','two':'dos'}

Access a value with the key

word = input("what word would like to translate to spanish? ")
palabra = spanishDictionary[word]

Add a new key and value:

spanishDictionary.update({'blue':'azul'})
print(len(spanishDictionary))

Delete a key and the value:

del(spanishDictionary['blue'])

Replace the value of a key:

spanishDictionary['goodbye'] = 'chau'

Remove all items:

spanishDictionary.clear()

You can have a different type of value:

numbers = {'one':1,'two':2,'three':3,'four':4,'five':5}


print( numbers['two'] * numbers['three'])

You can have a different type of key and a different type of value:

numbers = {90:0,91:1,92:2,93:3}

print(numbers[92] * numbers[93])

Homework:
Add ten more words to the dictionary. Write a sentence in English and then translate it to Spanish or the language you chose. Add this new code to the original post.
