Differentiate between the following:

1. f = open(‘diary.txt’, ‘r’)
2. f = open(‘diary.txt’, ‘w’)

Write a method in python to read the content from a text file diary.txt line by line and display the same on screen.

Consider the following definition of class Member, write a method in python to write the content in a pickled file member.dat.

class Member:
	def_init_(self,Mno,N) :
	self.Memno=Mno
	self.Name=N
	def Show(self):
		Display (self.Memno, '#',self.Name)
	def store_data(self):
		piFile = open('member.dat','wb')
		pickle.dump(self, piFile)
		piFile.close()
