Python is a well-known high-level programming language. The Python script is basically a file containing code written in Python. The file containing Python script has the extension ‘.py’ or can also have the extension ‘.pyw’ if it is being run on a Windows machine. In this article, we will learn how to run a Python program. To run a Python script, we need a Python interpreter that needs to be downloaded and installed.

Different ways to run Python Script

Here are the ways using which we can run a Python script.

  1. Interactive Mode
  2. Command Line
  3. Text Editor (VS Code)
  4. IDE (PyCharm)

Here is a simple Python script to print ‘Hello World!’.

print('Hello World!')

Here, the print() function is to print out any text written within the parenthesis. We can write the text that we want to be printed using either a single quote as shown in the above script or a double quote.

If you are coming from any other language then you will also notice that there is no semicolon at the end of the statement as, with Python, you do not need to specify a semicolon at the end of the line. And also we don’t need to include or import any files to run a simple Python script.

There are various ways to run a Python script but before going toward the different ways to run a Python script, we first have to check whether a Python interpreter is installed on the system or not. So in Windows, open ‘cmd’ (Command Prompt) and type the following command.

python -V

This command will give the version number of the Python interpreter installed or will display an error if otherwise.

How to Run Python Script Interactively

In Python Interactive Mode, you can run your script line by line in a sequence. To enter an interactive mode, you will have to open Command Prompt on your Windows machine and type ‘python’ and press Enter.

Example1: Run the following line in the interactive mode:

print('Hello World !')


Example 2: Run the following lines one by one in the interactive mode.

name = "Aakash"
print("My name is " + name)


Example 3: Run the following line one by one in the interactive mode.

a = 1
b = 3
if a > b:
    print("a is Greater") 
    print("b is Greater")


Note: To exit from this mode, press ‘Ctrl+Z’ and then press ‘Enter’ or type ‘exit()’ and then press Enter.

How to Run Python Script by the Command Line

To run a Python script store in a ‘.py’ file in the command line, we have to write ‘python’ keyword before the file name in the command prompt.


You can write your own file name in place of ‘’.


Running Python Scripts using a Text Editor

To run Python script on a text editor like VS Code (Visual Studio Code) then you will have to do the following:

  • Go to the extension section or press Ctrl+Shift+X on Windows, then search and install the extension named ‘Python’ and ‘Code Runner’. Restart your vs code after that.
  • Now, create a new file with the name ‘’ and write the below code in it:
    print('Hello World!')
  • Then, right-click anywhere in the text area and select the option that says ‘Run Code’ or press Ctrl+Alt+N to run the code.


Running Python Scripts using an IDE

To run Python script on an IDE (Integrated Development Environment) like PyCharm, you will have to do the following:

  • Create a new project.
  • Give a name to that project as ‘GfG’ and click on Create.
  • Select the root directory with the project name we specified in the last step. Right-click on it, go to New, anto, and click on the ‘Python file’ option. Then give the name of the file as ‘hello’ (you can specify any name as per your project requirement). This will create a ‘’ file in the project root directory.

Note: You don’t have to specify the extension as it will take it automatically.

  • Now write the below Python script to print the message:
print('Hello World !')
  • To run this Python script, Right click and select the ‘Run File in Python Console’ option. This will open a console box at the bottom and show the output there. We can also run using the Green Play Button at the top right corner of the IDE.
