How to print the name of a list?

[oriana.falco]

Hi!

I was wondering what can I do to print the name of a list that is
inside a list. For example:


exported = ['123','456']
imported = ['789','012']

client1 = ['cl1b','cl1a']
client2 = ['cl2a','cl2b']

host = ['imported','exported']
client = ['client1','client2']

list = ['host', 'client']

My goal is to print a string that reads:
'host imported 789'
...and subsequently print more strings that read:
'host imported 012'
'host exported 123'
'host exported 456'
......


Thanks in advance for the help....

In general, no --- there is no unique mapping between references and
names.

For debugging, however, it is sometimes useful to try this kind of
reverse lookup by iterating over the global dictionary:

def guess_name(thing):
for name, reference in globals.iteritems():
if thing is reference:
return name
else:
return None

# example use:

foo = [1, 2, 3]
bar = [4, 5, 6]
baz = [foo, bar]

for thing in baz:
print guess_name(thing)

# prints "foo" and "bar"


I should emphasize that this is NOT failsafe, and it shouldn't be used
in any way except for debugging IMHO. If you need to associate names
with objects in a guaranteed way, use a dictionary.

def printContents(seq, output=""):
for itemname in seq:
item = globals().get(itemname, None)
if isinstance(item, (list, tuple)):
printContents(item, "%s%s " % (output, itemname))
else:
print "%s%s" % (output, itemname)

exported = ['123','456']
imported = ['789','012']

client1 = ['cl1b','cl1a']
client2 = ['cl2a','cl2b']

host = ['imported','exported']
client = ['client1','client2']

# you shouldn't reassing 'list', so let's call it something else
namelist = ['host', 'client']

printContents(namelist)


Output:
host imported 789
host imported 012
host exported 123
host exported 456
client client1 cl1b
client client1 cl1a
client client2 cl2a
client client2 cl2b


Let me know if this wasn't what you wanted

Wow, thanks.....that's a neat little function....I'll still check out
the dictionary stuff. For now, this helps a lot though...

THANKS!!!
