How to use a different delimiter for Python Template?
Python template is a super powerful feature that can help you to fill the placeholders on the fly. But by default, the delimiter used by python for the template is a dollar
$ , though this is perfect, at times you might need to use dollar in your final string and that is when it might be handy to overwrite the default delimiter with something uncommon. For example, we shall use
%$% in our case. Since Template is a class that uses delimiter property, so to override the delimiter we have to extend the class to which overrides the delimiter property.
from string import Template class CustomTemplate(Template): delimiter = '%$%' template_string = "This is %$%custom string. This is %$%another string." template = CustomTemplate(template_string) output = template.substitute(custom="first", another="second") print(output) # Output # This is first string. This si second string.
In the above example, we have extended
CustomTemplate which is overriding the
delimiter property with
%$% . In the following lines, you can see the use case of the
substitute to replace the content with the variables passed.
