If you really don't want an array (list, or tuple) of these (i.e.,
var[1], var[2], var[3], ...), then you can get at a dictionary that
contains all the local variables -- names and values -- like this:


>>> var1 = "blah"
>>> var2 = "blahblah"
>>> var3 = "blahblahblah"
>>> var4 = "...."
>>> locals()
{'var4': '....', 'var1': 'blah', 'var3': 'blahblahblah', 'var2':
'blahblah', '__builtins__': <module '__builtin__' (built-in)>,
'__file__': '/home/gherron/.startup.py', '__name__': '__main__',
'__doc__': None}

>>> for v,k in locals().items():
... if v.startswith('var'):
... print k
...
....
blah
blahblahblah
blahblah
>>>
