Each instantiation for argument. Templates reduce a lot of writers' work. We do not have to implement functions multiple times just because it's a slightly different type. There are different types of templates: Function-templates

to do is to provide and, or, and not class templates that wrap matchers and implement operator() appropriately. The resulting matcher will be an expression template. ## and Matcher 1: template expression template. ## Boolean algebra primer/refresher In upcoming slides you'll see some v B reads "A or B" • means not: ¬A reads "not A" ## OK, now what? We have an expression template representing a combination of matchers that can be run on a message. ![Image](/uploa

Life is wonderful! os.path.join(PROJECT_PATH, "templates") ) Add at least one template to CMS_Templates; for example: CMS_Templates = ( ('template_1.html', 'Template One') The templates you define in CMS_Templates have to exist at runtime and contain at least one {% placeholder %} template tag to be useful for Django CMS. For more details see Creating templates The Creating templates Django CMS uses templates to define how a page should look and what parts of it are editable. Editable areas are called placeholders. These templates are standard Django templates and you
