converting dictionaries

this is my dictionary

dict = {'apple':'der Apfel', 'ant':'die Ameise', 'asparagus':'der Spargel'}

i would like to get an output:

dictionary for a
apple: der Apfel
ant:die Ameise
asparagus:der Spargel

I am new to dictionaries please help

i tried doing

def tutorial8_part2():
  dict = {'apple':'der Apfel', 'ant':'die Ameise', 'asparagus':'der Spargel'}
  dictList = dict.items()
  for key, value in dict.iteritems():
    temp = []
    aKey = key
    aValue = value
    temp.append(aKey)
    temp.append(aValue)
    dictList.append(temp)
    print dictList.append(temp)

but its not working

If you just want to print out each key and value pair in a long line, you can do this:

dict = {'apple':'der Apfel', 'ant':'die Ameise', 'asparagus':'der Spargel'}
for key, value in dict.items():
  print key + ':', value,
print

The output will probably not be in the same order as when you created the dictionary. Iterating through a dictionary doesn't guarantee any particular order, unless you specifically sort the keys, for example with the sorted() built-in function:

for key, value in sorted(dict_.items()):  
    print "{0}: {1}".format(key, value)

Will this do what you are trying to do?

(EDIT: updated to the new output format)

my_dict = {'apple':'der Apfel', 'ant':'die Ameise', 'asparagus':'der Spargel'}

print 'dictionary for a'
for k, v in my_dict.iteritems():
     print '%s:%s' % (k, v)

yields:

dictionary for a
ant:die Ameise
asparagus:der Spargel
apple:der Apfel

Note that this order is different from the one you posted, but the question didn't make it clear if order mattered.

As correctly suggested by @wim, it's better not to use dict as a variable name.

If you are just trying to iterate through a dictionary, to print key and value pairs:

>>> dict_ = {'apple':'der Apfel', 'ant':'die Ameise', 'asparagus':'der Spargel'}
>>> for k,v in dict_.iteritems():
...   print k, ':', v
... 
ant : die Ameise
asparagus : der Spargel
apple : der Apfel

In one-line using a generator expression:

>>> print '\n'.join('{}: {}'.format(k,v) for k,v in dict_.iteritems())
ant: die Ameise
asparagus: der Spargel
apple: der Apfel

As a side note, avoid using dict as a variable name because it shadows the built-in.
