Why this reverse lookup function not working

[Emekadavid]

Please, can someone help me explain why this reverse lookup is not working. If I input any of the values in the dictionary, it says not found. Baffled.

mydict = {'a':2, 'b':4, 'c': 5, 'u':98}
#do reverse lookup
v = input('enter a key >')
def reverse_lookup(d, v):
    for keys in d :
        if d[keys] == v :
            print('found')
            return keys
        else :
            print('not found')
            
print(reverse_lookup(mydict, v))

Thanks

Thanks. But the reference is very old. I am using python 3. The reference is for python 2. I tried out using mydict.values() and received a dict_values types and not a list which was the implementation in python 2. I don't know how to traverse a dict_values type. If you can show me, then I would be happy.

input returns str and the values in the dict are int, so the user input and [any] value from the dict will never be equal.
Do you really want to print 'not found' for each not equal value? Also there are better ways to iterate over dict:

for key, value in some_dict.items():
    # do something with key and value

Thanks. This solution is more intuitive and it worked.
