Program to print hello world in python

Python Hello World

Summary: in this tutorial, you’ll learn how to develop the first program in Python called “Hello, World!”.

If you can write “hello world” you can change the world.

Creating a new Python project

First, create a new folder called helloworld .

Second, launch the VS code and open the helloworld folder.

Third, create a new app.py file and enter the following code and save the file:

print('Hello, World!')Code language: Python (python)

The print() is a built-in function that displays a message on the screen. In this example, it’ll show the message ‘Hello, Word!’ .

What is a function

When you sum two numbers, that’s a function. And when you multiply two numbers, that’s also a function.

Each function takes your inputs, applies some rules, and returns a result.

In the above example, the print() is a function. It accepts a string and shows it on the screen.

Python has many built-in functions like the print() function to use them out of the box in your program.

In addition, Python allows you to define your functions, which you’ll learn how to do it later.

Executing the Python Hello World program

To execute the app.py file, you first launch the Command Prompt on Windows or Terminal on macOS or Linux.

Then, navigate to the helloworld folder.

After that, type the following command to execute the app.py file:

python app.pyCode language: Python (python)

If you use macOS or Linux, you use python3 command instead:

python3 app.pyCode language: CSS (css)

If everything is fine, you’ll see the following message on the screen:

Hello, World!Code language: Python (python)

If you use VS Code, you can also launch the Terminal within the VS code by:

• Accessing the menu Terminal > New Terminal
• Or using the keyboard shortcut Ctrl+Shift+` .

Typically, the backtick key ( ` ) locates under the Esc key on the keyboard.

Python IDLE

Python IDLE is the Python Integration Development Environment (IDE) that comes with the Python distribution by default.

The Python IDLE is also known as an interactive interpreter. It has many features such as:

In short, the Python IDLE helps you experiment with Python quickly in a trial-and-error manner.

The following shows you step by step how to launch the Python IDLE and use it to execute the Python code:

First, launch the Python IDLE program:

A new Python Shell window will display as follows:

Now, you can enter the Python code after the cursor >>> and press Enter to execute it.

For example, you can type the code print(‘Hello, World!’) and press Enter , you’ll see the message Hello, World! immediately on the screen:

Summary

• Use the python app.py command from the Command Prompt on Windows or Terminal on macOS or Linux to execute the app.py file.
• Use the print() function to show a message on the screen.
• Use the Python IDLE to type Python code and execute it immediately.

Python is a high-level, interpreted programming language that has become one of the most popular languages in the world. It’s known for its simplicity, readability, and ease of use, which makes it a perfect language for beginners. One of the first things you’ll learn in Python is how to print “Hello, World!” to the console. In this article, we’ll walk you through the simplest and most effective ways to print “Hello, World!” in Python.

The Simplest Way to Print “Hello, World!”

Printing “Hello, World!” in Python is as simple as using the built-in print() function. This function is used to display output to the console. To print “Hello, World!”, all you need to do is use the following code:

This code will print “Hello, World!” to the console. It’s important to note that the print() function automatically adds a newline character at the end of the string, so you don’t need to add it manually.

To execute this code, you can create a new Python file, write the code, and then run the program from the console. Here’s an example of how to do this on a Windows machine:

1. Create a new file called hello_world.py and add the code above to it.
2. Open the command prompt and navigate to the directory where the file is saved.
3. Type python hello_world.py and press enter.
4. The console should display “Hello, World!”.

Various Methods to Print “Hello, World!”

While the print() function is the simplest way to print “Hello, World!” in Python, there are other ways to achieve the same result. One of the most common ways is to use the sys library. This library provides access to some variables used or maintained by the interpreter and to functions that interact strongly with the interpreter. Here’s an example of how to print “Hello, World!” using the sys library:

import syssys.stdout.write("Hello, World!\n") 

Another way to print “Hello, World!” is to concatenate strings and pass them to the print() function. Here’s an example:

This code will also print “Hello, World!” to the console.

Python Features for the “Hello, World!” Program

While printing “Hello, World!” is a simple task, it’s a great way to learn some of the features of Python. One of the most important features is string manipulation. In Python, you can easily manipulate strings using built-in functions and operators. Here’s an example of how to print “Hello, World!” three times using string manipulation:

This code will print “Hello, Hello, Hello, World!” to the console.

Another important feature of Python is writing functions. Functions are blocks of code that can be reused throughout your program. Here’s an example of how to write a function to print “Hello, World!»:

def hello_world(): print("Hello, World!")hello_world() 

This code will print “Hello, World!” to the console when the hello_world() function is called.

PyCharm IDE for Python

PyCharm is an Integrated Development Environment (IDE) for Python programming language . It provides a lot of features that help you write, debug, and test your Python code. Here’s how to set up PyCharm and create a new Python file:

1. Download and install PyCharm from the official website.
2. Open PyCharm and click on “Create New Project”.
3. Choose a location to save your project.
4. Select the Python interpreter you want to use.
5. Click on “Create”.
6. Right-click on the project folder and select “New” > “Python File”.
7. Name the file hello_world.py .
8. Add the code to print “Hello, World!” to the file.
9. Run the program by right-clicking on the file and selecting “Run” > “hello_world”.
