Using Python 2.6 or higher: Is there a way to configure
string.Template() to ignore the case of matched identifiers?
In other words, given the following Template string and
dictionary where all keys are lowercase, is there a way to have
my identifiers expanded based on their lowercase values?
import string
values = dict( name='John Doe', phone='999-555-1212' )
output = string.Template( 'My name is $NAME and my phone is
$Phone.' ).safe_substitute( values )
If you can guarantee the identifiers are all lowercase inside the
dictionary:
class lowercase_dict(dict):
def __getitem__(self, name):
return dict.__getitem__(self, name.lower())
import string
values = lowercase_dict( name='John Doe', phone='999-555-1212' )
output = string.Template( 'My name is $NAME and my phone is $Phone.'
).safe_substitute( values )
py> output
'My name is John Doe and my phone is 999-555-1212.'
If you cannot guarantee that, subclass string.Template:
class lowercase_template(string.Template):
def safe_substitute(self, mapping=None, **kws):
if mapping is None:
mapping = {}
m = lowercase_dict((k.lower(),v) for k,v in mapping.items())
m.update(lowercase_dict((k.lower(),v) for k,v in kws.items()))
return string.Template.safe_substitute(self, m)
