Introduction
Template pattern defines a basic algorithm in a base class using the abstract operation where subclasses
override the concrete behavior.
Template patterns help to keep the
algorithm outline in a separate method so this method is known as the template
method.
Some of the different features of the
template pattern-
- Define is the skeleton of an algorithm in an operation.
- Includes subclasses, which help us to the redefine certain steps of an algorithm.
Let’s take an example:
class MakeMeal:
def prepare(self): pass
def cook(self): pass
def eat(self): pass
def go(self):
self.prepare()
self.cook()
self.eat()
class MakePizza(MakeMeal):
def prepare(self):
print("Prepare Pizza")
def cook(self):
print("Cook Pizza")
def eat(self):
print("Eat Pizza")
class MakeTea(MakeMeal):
def prepare(self):
print("Prepare Tea")
def cook(self):
print("Cook Tea")
def eat(self):
print("Eat Tea")
makePizza = MakePizza()
makePizza.go()
print 25*"+"
makeTea = MakeTea()
makeTea.go()
Output
The output of the
above program-
Explanation
The
code creates a template to prepare food. Each parameter represents the
attribute to create a part of food like coffee, Maggi, etc.
The output represents the visualization of attributes.
