not on my side, modifying this dict with the missing key-value apparently does what you want also :

Python 2.7.6 (default, Mar 22 2014, 22:59:56) 
[GCC 4.8.2] on linux2

>>> 
>>> import email.charset
>>> email.charset.ALIASES
{'latin-8': 'iso-8859-14', 'latin-9': 'iso-8859-15', 'latin-2': 'iso-8859-2', 'latin-3': 'iso-8859-3', 'latin-1': 'iso-8859-1', 'latin-6': 'iso-8859-10', 'latin-7': 'iso-8859-13', 'latin-4': 'iso-8859-4', 'latin-5': 'iso-8859-9', 'euc_jp': 'euc-jp', 'latin-10': 'iso-8859-16', 'ascii': 'us-ascii', 'latin_10': 'iso-8859-16', 'latin_1': 'iso-8859-1', 'latin_2': 'iso-8859-2', 'latin_3': 'iso-8859-3', 'latin_4': 'iso-8859-4', 'latin_5': 'iso-8859-9', 'latin_6': 'iso-8859-10', 'latin_7': 'iso-8859-13', 'latin_8': 'iso-8859-14', 'latin_9': 'iso-8859-15', 'cp949': 'ks_c_5601-1987', 'euc_kr': 'euc-kr'}
>>> 
>>> for i in range(1, 16):
	c = 'iso-8859-' + str(i)
	email.charset.ALIASES[c] = c

	
>>> 
>>> iso7 = email.charset.Charset('iso-8859-7')
>>> iso7
iso-8859-7
>>> str(iso7)
'iso-8859-7'
>>>
