Now, the valid value entered is converted into integer value.
float(): It is used to change the input value into floating-point value. For example,
a = float(input("Enter a number "))
Now, the valid value entered is converted into floating-point value.
The print() Function
The print() function prints or sends the output to the standard output device, which is usually a
monitor. This function auto converts the items to strings, i.e., if you try printing a numeric value,
the print() function will automatically convert it into equivalent string and print it. The print()
function also introduces spaces between items automatically.
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.

print( ) functions.
age = input ("Enter your age:") Enter your age: 12
name = input ("Enter your name: ") Enter your name: Ankit
print (name, "your age is," age) Ankit your age is 12
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.
name = "John" # name variable is of type str
age = 10 # age variable is of type num
print(name)
print(age)
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)
