Creator Guido van Rossum named the language 'Python', after the popular
BBC comedy series "Monty Python's Flying Circus”. He wanted to select a
name that was a little bit mysterious and unpredictable.
Input Statement in Python
In python, to take input from the user we use input() function. This input() function prompts the
user to enter data.
Syntax:
input([prompt])
This input() considers everything as string. Whether the user enters a number or a string but the
input() treats them as strings only. So, in order to consider the input value as other than string, we
have to convert it into other datatype.
For example:
A=input("Enter your Name") #Here the input entered is String
B=input("Enter your marks") ' ' 'Here the input is again String, but we
cannot do calculations on String. So it is converted into other data types.' ' '
Thus, the changed statement will be:
B=int(input("Enter your Marks") ) #To enter integer data values.
C=float(input("Enter your Price of the item")) #To input decimal values.
Output Statement in Python
The print() outputs a complete line and then moves to the next line for subsequent output.
Syntax:
print(value1, value2,....., valueN)
For example:
a=10
print("value of a",a)
Example 1: Input and Output statements in Python
Program: Output:
#Python program to swap two variable values
enter first number 23
num1=int(input("enter first number"))
enter second number 45
num2=int(input("enter second number"))
Now the value of num1 45
temp=num1
Now the value of num2 23
num1=num2
num2=temp
print("Now the value of num1",num1)
print("Now the value of num2",num2)
