Get particular value from dictionary

How to get a particular key from dictionary in python?

I have a dictionary as : 

dict = {'redorange':'1', 'blackhawak':'2', 'garlicbread':'3'}

I want to get value of that key which contains garlic in its key name.
How I can achieve it?

Let's call your dictionary d:

print [v for k,v in d.iteritems() if 'garlic' in k]

prints a list of all corresponding values:

['3']

If you know you want a single value:

print next(v for k,v in d.iteritems() if 'garlic' in k)

prints

'3'

This raises StopIterationError if no such key/value is found. Add the default value:

print next((v for k,v in d.iteritems() if 'garlic' in k), None)

to get None if such a key is not found (or use another default value).
