Python Input and Output(input() & print())

 Python Input and Output(input() & print())

Introduction

Just like we need clear instructions in real life to complete a task, Python programs need input from users to work correctly. In Python, we take input using the input() function, and after processing that input, we display the result as output using the print() function.

In this blog, you'll learn Python Input and Output with easy examples.

What is Output in Python?

 Output means showing something on the screen. Python uses the print() function to display output.

Example:

print("Hello, world!")

Output:

Hello, world!

Printing Multiple Values

You can print multiple values in one line.

Code:

name = "Sundeep"
age = 21

Output:

Sundeep 21

Print Text with Variable

Code:

name = "Python"
print("I am learning", name)

Output:
I am learning Python

What is Input in Python?

Input means taking data from the user. Python uses the input() function to take user input.

Example:
name = input("Enter your name:")
print("Welcome", name)

But remember, by default, the input() function always takes input as a string.

Example:

a= input("Enter the number1: ")
b=input("Enter the number2:")

print("result by adding a and b:", a + b )

Output:
Enter the number1: 10
Enter the number2: 20
result by adding a and b: 1020
 
Here, even if you enter a number, Python will return the value as text(string), that's why, instead of adding two numbers, Python concatenated them. So to take integer or decimal numbers, we need to convert input using the int() function for integer type and the float() function for decimal numbers.

Example:

a= int(input("Enter the number1: "))
b=int(input("Enter the number2:"))

print("result by adding a and b:", a + b )

Output:
Enter the number1: 10
Enter the number2: 20
result by adding a and b: 30

Conclusion

  • input() used to take input.
  • print()  used to display output.
  • input() has string as default type.

Practice Questions (Must Try)

  1. Take a number and print a welcome message.
  2. Take two numbers and print their sum.
  3. Take length and breadth and calculate the area of a rectangle.
  4. Take marks and Display percentage.
  5. Ask the user's age and print whether they can vote.

Python Conditional Statements(if, elif, else)

 Python Conditional Statements(if, elif, else)   Introduction In real life, we take decision every day like if rain then take an umbrella, if phone battery is low then charge it, etc. Similarly, in python, conditional statement are used for decision making. In this blog, you'll learn: What conditional statements are if, elif and else What Are Conditional statements? Conditional statements allow a program to perform different action based on whether a certain condition is true or false.  Suppose if we have to find the given number is divisible from 2 or not. Python mainly uses : if  elif else   Let's take above example: Code: #find numbers divisible by two and which are not. b=13 if b%2==0:     print("b is divisible by 2") else:     print("b is not divisible by 2") Output: b is not divisible by 2 The if  Statement The if statement runs code only when the condition is true. if statement can not be written without condition....

Introduction To Database Management System

  Introduction to Database Management System In engineering and computer science, DBMS (Database Management System) is one of the most important subjects. It is not only useful for exams like GATE and placement, but also essential for real-world software development. In this blog, we will cover: What is DBMS Why DBMS is needed Advantages of DBMS Application of DBMS Everything is explained in a simple and beginner-friendly way. What Is DBMS? A database-management system (DBMS) is a collection of interrelated data and a set of programs to access those data. The primary goal of a DBMS is to provide a way to store, manage and retrieve data easily. Some other operation can also be performed on database such as adding, updating and deleting data.  Instead of storing data in files, DBMS  stores data in structured format (tables). Examples of DBMS MySQL Oracle PostgreSQL SQL Server Why Do We Need DBMS? Earlier, data was stored using file systems, which caused many problems s...
