#Adding Method - part of inheritance

#Add a method called welcome to the Student class.

class Person:

  def __init__(self, fname, lname):

    self.firstname = fname

    self.lastname = lname

  def printname(self):

    print(self.firstname, self.lastname)

class Student(Person):

  def __init__(self, fname, lname, year):

    super().__init__(fname, lname)

    self.graduationyear = year

  def welcome(self):

    print("Welcome", self.firstname, self.lastname, "And Your Birth Year=", self.graduationyear)

    self.printname()

x = Student("Rahul", "Shinde", 2000)

x.welcome()

Output:

Welcome Rahul Shinde And Your Birth Year= 2000

Rahul Shinde

#Scope of Variable - Global and Local variable

#Changing value of global variable

x = 300

def myfunc():

  global x

  x = 200

  print("Value of x in myfunc():",x)

print("Value of x in python main script:",x,"Before calling myfunc()")

myfunc()

print("Value of x in python main script:",x,"Afte calling myfunc()")

Output:

Value of x in python main script: 300 Before calling myfunc()

Value of x in myfunc(): 200

Value of x in python main script: 200 Afte calling myfunc()

---

# Global Keyword

# If you need to create a global variable,

# but are stuck in the local scope, you can use the global keyword.

#

# The global keyword makes the variable global.

def myfunc():

  global x

  x = 300

  print("Value of x in the myfunc():",x)

myfunc()

def valueofx():

  print("Value of x in valueofx():",x)

print("Value of x in main python script:",x)

valueofx()

Output:

Value of x in the myfunc(): 300

Value of x in main python script: 300

Value of x in valueofx(): 300

---

# Naming Variables

# If you operate with the same variable name inside and outside of a function,

# Python will treat them as two separate variables,

# one available in the global scope (outside the function)

# and one available in the local scope (inside the function).

x = 300

def myfunc():

  x = 200

  print("Value of x in myfunc():",x)

myfunc()

print("Value of x in python main script:",x)

Output:

Value of x in myfunc(): 200

Value of x in python main script: 300

---

# Global Scope

# A variable created in the main body of the Python code is a global

# variable and belongs to the global scope.

#

# Global variables are available from within any scope, global and local.

#x = 300

#x is global variable

x = 300

def myfunc():

  print("Value of x in myfunc():",x)

def valueofx():

  print("Value of x in valueofx():",x)

myfunc()

print("Value of x from the main python script:",x)

valueofx()

Output:

Value of x in myfunc(): 300

Value of x from the main python script: 300

Value of x in valueofx(): 300

---

# Function Inside Function

#nested function

# As explained in the example above,

# the variable x is not available outside the function,

# but it is available for any function inside the function.

def myfunc():

  x = 300

  print("Value of x in the myfunc:", x)

  def myinnerfunc():

    print("Value of x in the myinnerfunc:",x)

    def partmyinnerfunc():

      print("Value of x in the partmyinnerfunc:", x)

    partmyinnerfunc()

  myinnerfunc()

myfunc()

#print("Value of x in the main script of python:",x)

Output:

Value of x in the myfunc: 300

Value of x in the myinnerfunc: 300

Value of x in the partmyinnerfunc: 300

---

# A variable is only available from inside the region it is created.

# This is called scope.

# Local Scope

# A variable created inside a function belongs to the local scope of that function,

# and can only be used inside that function.

def myfunc():

  x = 300

  print("Value of x:",x)

  print("x is local variable")

  print("x+10=",x+10)

myfunc()

#print(x)

Output:

Value of x: 300

x is local variable

x+10= 310
