P. 102
On the output screen, a=10 and b=20 will be printed. You can also assign the same value to
multiple variables at the same time in the following way:
a = b = 20
print ("a=", a)
print ("b=", b)
On the output screen, a = 20 and b = 20 will be printed.
You can also assign multiple values to multiple variables in the same line in the following
way:
name, age, grade="Deepak", 12, ‘VII’
print ("Name is", name)
print ("Age is", age)
print ("Grade is", grade)
On the output screen, Name is Deepak, Age is 12 and Grade is VII will be printed.
You must follow the given rules while creating and naming the variables:
A variable name must start with a letter or underscore character.
A variable name cannot start with a number.
A variable name can only contain alphanumeric characters (all the letters and numbers) and
underscores (_).
Variable names are case-sensitive.
Variable names cannot contain any special character or symbol.
A keyword cannot be used as a variable name.
DATA TYPES
A data type specifies the type of value a variable contains. For example, a person’s name must
be stored as a string value whereas the person’s age must be stored as an integer. Data types
in Python are:
int: Positive or negative whole numbers (without any fractions). Example: a = 3, b= -5
float: Any positive or negative real number in which a fraction is denoted by a decimal
number. Example: a = 3.5
string: A string value is a collection of one or more characters put in single or double quotes.
Example: a="hello"
COMMENTS IN PYTHON
Comments in Python can be used to explain parts of the code. It can also be used to hide the code
as well. Comments enable us to understand the way a program works. In python, any statement
starting with # symbol is known as a comment. Python does not execute comments. Comments
are not a part of the program, but they do enhance the interactivity of the program and make it
readable. Python supports two types of comments: Single line comment and Multiline comment.
