Components Of the Program : The components often considered as Tokens
 
1. The parts of the program made out of the Basic Character Set(A-Z,a-z,0-9,%^&*...) are known as tokens
2. The various tokens are

    a. Comments: 1. The comments are the componentsof the the program that give the un interpreted information starting with 
                    #Followed by a comment
                 2. The comment is made in a single line

    b. Keywords : 1. A keyword is aword that is used in the program for a specific use.
                     if,else,and...etc


    c. Whitespace characters :   
	   1.  Using  ' '  ,Enter key --> Line space, tab key --> tabspace
       2.Indentation refers to spacing and it is one of the most important components of a python program

    d. Literals or Constant :  
	   1. A constant or a literal is a fixed value in the program that do not change
	   2. In Python we have the following four types of constant
		 1. Numeric Literal or Constant
		 2. String Literal or Constant
		 3. Boolean Literal or Constant
		 4. None Literal Constant
							 
	   1. Numeric Literal or Constant :
		  1. These are nothing but the numbers that we use in the daily life
		  2. These are divided in to 3 categories
			 1. Integer    2. Floatpoint   3. Complex    

			 1. Integer :1.  Integer means positive numbers, negative numbers and even zero    	
			   Ex:. 9,-69,0	
			 2. These are the countable quantities
			   Ex: There are 15 people in the seminar 
			 3. They come up in one part i.e., IntegerPart  only 
			 
	   2. Floatpoint:  1. Floatpoint   means positive numbers, negative numbers and even zero with a decimal point  	
							 Ex: 32.25,14.21
					   2. These are the measurable quantities	
							  Ex: The temperature is -11.23 degrees
					   3. They come up in three part i.e., IntegerPart  only ,decimalpoint,fractionalpart 
					   
	   3. complex: These numbers have two parts  1. Real part 2. Imagainary Part
				Ex: 6-8j --> 6--> Real Part ,8 --> Imaginary part  

	  Under Integers we can have  4 types of Integers
	  1. Decimal Integer :1.  The integer formed by 0-9 digits(General or default format) 
						  2. These are the numbers with base10  
                                                       
                   
		a = 10
		b =  5
		c = a*b
		print(c)


		#This Program is for addition
		a = 10
		b =  5
		c = a*b
		print(c)


		z = 11/5
		print(z)

		d = 11/5
		print(d)

		e = 1 1/5
		print(e)

		#Syntax error

		   e = 1 1/5
				  ^
		SyntaxError: invalid syntax


		e = 1+(1/5)
		print(e)


		6-8j
