I am writing a small application for a freind of mine, and it includes a dictionary. I need to have the user input the 'key' value and have the program output the 'value' value. Any ideas on how to do this?
P.S. - A way to inform the user that a key is not in the dictionary would also be nice.

Try this:

myDict = {} # Create your own
userKey = input()
if userKey in myDict:
    myValue = myDict[userKey]
    print('Value is found: {}'.format(myValue))
else:
    print('No such key!')

Or you may prefer this one:

myDict = {}
userKey = input()
myValue = myDict.get(userKey, 'No such key!')
print(myValue)

Try this:

myDict = {} # Create your own
userKey = input()
if userKey in myDict:
    myValue = myDict[userKey]
    print('Value is found: {}'.format(myValue))
else:
    print('No such key!')

Or you may prefer this one:

myDict = {}
userKey = input()
myValue = myDict.get(userKey, 'No such key!')
print(myValue)
