The general syntax of the print() function is as follows:
print (<expression 1> , <expression 2>...)
For example:
print ("Python is easy").
Let's create a program to use the input( ) and print( ) functions.
Using input() and print() functions
VARIABLES IN PYTHON
Variables are memory reference points where we store values which can be accessed or changed
later. The names given to the variables are known as identifiers. In Python, we do not need to
specify the type of variable because Python is a dynamically typed language and it identifies the
variable type automatically. Let’s understand this with the help of the given examples.
num = 0.4
_price = 30.3
TOTAL = round(_price * num,2)
print(TOTAL)
Declaring and Initializing a Variable
In Python, variables are declared and initialized at the same time in the following way:
a = 10
b = 20
print ("a=", a)
print ("b=", b)
On the output screen, a = 20 and b = 40 will be printed. You can also assign the same value
to multiple variables at the 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.
