Simple Dictionary Question

Expand Post »

Hi, I have been learning Python and have a quick dictionary question.

I am trying to make a "vocabulary test" to help myself study, and am trying to do it with a dictionary. So far I have this:

python Syntax (Toggle Plain Text)
testwords = {"uno":"one","dos":"two","tres":"three","cuatro":"four",\
             "cinco":"five"}
 
def vocabtest():
    for value in testwords:
        print "What word does the following definition correspond with?"
        print value
        answer = raw_input("> ")
        if answer == :
            print "Correct!"
 
vocabtest()
testwords = {"uno":"one","dos":"two","tres":"three","cuatro":"four",\
             "cinco":"five"}

def vocabtest():
    for value in testwords:
        print "What word does the following definition correspond with?"
        print value
        answer = raw_input("> ")
        if answer == :
            print "Correct!"

vocabtest()

I need help with line 9, "if answer == :".
I am not sure how I would check to see if the user's answer is equal to the corresponding key.

Any help would be greatly appreciated. Thanks.

Re: Simple Dictionary Question

An appropriate variable name in the for loop would be key instead of value, because you are iterating on the keys of the dictionary.

Python Syntax (Toggle Plain Text)
        if answer == testwords[key]:
        if answer == testwords[key]:

Re: Simple Dictionary Question

I guess you want to write this

Python Syntax (Toggle Plain Text)
def vocabtest():
    for value in testwords:
        print "What word does the following definition correspond with?"
        print value
        answer = raw_input("> ")
        if (answer == testwords[value]):
          print "Correct!"
        else:
          print "No the answer is ",testwords[value]
def vocabtest():
    for value in testwords:
        print "What word does the following definition correspond with?"
        print value
        answer = raw_input("> ")
        if (answer == testwords[value]):
          print "Correct!"
        else:
          print "No the answer is ",testwords[value]
