Basic Python Programs

Let us begin with the simplest Python programs. Each program includes the complete source code, expected output and explanation.

Program 1 : Print "Hello World"

This is the first program that every Python programmer writes.

Program 1 : Print "Hello World"

This is the first Python program written by almost every beginner. The print() function is used to display output on the screen.

print("Hello World")

Output

Hello World

Explanation

• print() is a built-in Python function.
• It displays the text written inside double quotes.
• Anything inside quotes is treated as a string.

Program 2 : Print Your Name

Aadarsh Malviya

Explanation

The print() function displays the specified text exactly as written.

Program 3 : Print Multiple Lines

Write a Python program to print multiple lines.

print("Welcome")
print("To")
print("NoidaTut")

Output

Welcome
To
NoidaTut

Explanation

• Each print() statement prints on a new line.
• Python automatically moves the cursor to the next line.

Program 4 : Print Using Escape Character

20

Explanation

• The variable name stores a string.
• The variable age stores an integer.
• print() displays the value stored inside variables.

Program 6 : Print Using Separator

Write a Python program using the sep parameter.

print("Python","Programming","Tutorial",sep="-")

Explanation

The sep parameter specifies the separator placed between multiple values.

Program 7 : Print Using End Parameter

Write a program using the end parameter.

print("Python",end=" ")
print("Programming")

Output

Python Programming

Explanation

• Normally print() ends with a newline.
• The end parameter changes the ending character.
• Here a blank space is printed instead of a new line.

Programs Using User Input

Now let us learn programs that take input from the keyboard using the input() function.

Program 8 : Read and Display User Name

Write a Python program to accept the user's name and display it.

name = input("Enter your name : ")
