string bug/oddity?

[Oktay Safak]

Hi everyboby,

I am new to Python (and programming), so after reading
and studying the tutorial by Guido last night, I
decided to do some hands on experiments with the
interpreter and came across a quite strange behavior.

First I constructed a dictionary a. Here it is:

>>> a
{'yas': 23, 'ad': 'veli', 'soyad': 'guzel'}
>>> for x in a.keys():
	if type(a[x])!="string": print x+repr(a[x])
	else: print x, a[x]

yas23
ad'veli'
soyad'guzel'
>>> a
{'yas': 23, 'ad': 'veli', 'soyad': 'guzel'}
>>> for x in a.keys():
	if type(a[x])!="string": print x+repr(a[x])
	else: print x+a[x]

	
yas23
ad'veli'
soyad'guzel'

I just want to concatenate the two strings without the
quotes as in the last line. This works though:

>>> print x+a[x]
soyadguzel

Well, if you try it after getting rid of the first
entry in the dictionary which is a number then
everything is also OK:

>>> a
{'ad': 'veli', 'soyad': 'guzel'}
>>> for x in a.keys():
	print x+a[x]

	
adveli
soyadguzel


I couldn't understand why this happens.(I tried many
other ways to do it but no success) Is this a bug or
what? I searched the newsgroup archives but couldn't
find anything on this topic. Thanks for any help.
