sure is:

In [97]: mydict = {'knights':'say ni', 'death':'pointy teeth'}

In [98]: mydict.get('spam')

In [99]: mydict.get('knights')
Out[99]: 'say ni'

In [100]: if mydict.get(3):
   .....:     print 'Hi'
   .....:
   .....:

In [101]: if mydict.get('death'):
   .....:     print mydict['death']
   .....:
   .....:
pointy teeth
