Python Temp

Dictionaries / Maps

Definition (a unique key for every value stored):

{ Key1 : Value1, Key2 : Value2, Key3 : Value3, ...}

Classes / Objects

Definition:

class Class_name:
    __variable1 = variable1_value #private variable
    ...
    \#encapsulation
    def set_name(self, parameter1, ...)
        self.__variable1 = parameter1
    def get_name(self, parameter1, ...)
        return self.__variable1

Constructor:

def __init__(self, variable1, variable2, variable3,...):
    self.__variable1 = variable1
    self.__variable2 = variable2
    ...9

def get_type(self):
      print("Class_name")

def toString(self):
      return "{} is {} cm 
      tall".format(self.__variable1,self.__variable2) #{} to format output

Creating an object:

Object_name = Class_name(Value1, Value2, Value3,...)

Inheritance:

class Daughter_class_name(Mother_class_name):
    __Variable5 =  Value5
    ...
    def __init__(self, Variable1,..., Variable5)
        self.__Variable5 = Variable5
        super(Daughter_class_name, self).__init(Variable1,...) #superclass

    def set_Variable1(self, Variable1)
        self.__Variable1 = Variable1

    def get_Variable1(self)
        return self.__Variable1

    def to String(self):
        return "{}...{}...".format(self.__variable1,...,self.__variable5)

Method Overloading:

def Func_name(self,Var1=None) #no exception if no value for Var1 passed
    if Var1 is None:
        <Expression>
    else:
        <Expression>

Polymorphism:

Allows to refer to objects as their superclass and then have the correct functions called automatically.

class Test_class:
    def get_type(self, Mother_class_name):
        Mother_class_name.get_type()

Object_of_Test_class = Test_class()
Object_of_Test_class.get_type(Object_of_Mother_class)
Object_of_Test_class.get_type(Object_of_Daughter_class)

\#the correct get_type() function is called from each class definiton for each object

Write to a file:

file_variable.write(bytes(String+\n,'UTF-8'))

Open file, Read & Append mode:

file_variable = open("Directory_path", "ab+")
