Members of Template
g
- get_identifiers
- Returns a list of the valid identifiers in the template, in the order they first appear, ignoring any invalid identifiers.
i
- is_valid
- Returns False if the template has invalid placeholders that will cause substitute() to raise ValueError.
s
- safe_substitute
- Like substitute(), except that if placeholders are missing from mapping and kwds, instead of raising a KeyError exception, the original placeholder will appear in the resulting string intact.
- substitute
- Performs the template substitution, returning a new string.
t
- template
- This is the object passed to the constructor’s template argument.

>>> from string import Template >>> s = Template('$who likes $what') >>> s.substitute(who='tim', what='kung pao') 'tim likes kung pao' >>> d = dict(who='tim') >>> Template('Give $who $100').substitute(d) Traceback (most recent call last): ... ValueError: Invalid placeholder in string: line 1, col 11 >>> Template('$who likes $what').substitute(d) Traceback (most recent call last): ... KeyError: 'what' >>> Template('$who likes $what').safe_substitute(d) 'tim likes $what'
