As Python is one of the most popular high-level programming languages, it’s of utmost importance to know how to run a python script. A python script is nothing but a code written in python & structured into a file. The file contains an extension ‘.py’ or ‘.pyw’ if it’s for windows.

Let’s start by downloading & installing a python interpreter to run a python script.

Here is a basic python script to print ‘Hello World!

print('Hello World!')

From the above example, we can see a ‘print()’ function is used to print a written text within the parenthesis. The text can be written within a single quote or a double quote if the text contains a paragraph.

If you are no beginner & belong to other programming languages fundamentals, you may have noticed that there’s no semicolon is used at the end of a statement in python. Also, no need for any exclusive file inclusion to run a basic python script, unlike the C language.

Assuming you’ve installed the python interpreter, let’s check if the interpreter is working properly or not by opening the command prompt on your desktop & typing the following command.

python -v

Typing this command will give us the python interpreter version installed on your desktop.

Let’s Explore the Four Optional Ways to Run a Python Script.

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

Interactive Mode:

Here, you can run your python script line by line in a linear sequence. Interactive mode can be activated by opening the command prompt on your desktop & typing ‘python‘ & hitting Enter.

name = "Arjun"
print("Hello, my name is " + name)

Command Line

A ‘python‘ code is written before the file name in command prompt to run a Python script in a ‘.py‘ file in a command-line prompt. In the following code, you can write your own filename instead of ‘hello.py

python hello.py
Hello World!

print('Hello World!')
  • Now, right click in open space & select the option ‘Run Code’ to run the program.
Hello World!

IDE (PyCharm)

The following steps can be accounted to run a Python script on an Integrated Development Environment such as (PyCharm)

  • Create a new project.
  • Name the project as ‘TechsTricks‘ & click on Create.
  • Select to open the root directory with the project name associated with the last step & open it.
  • Navigate to New & select the ‘Python.file‘ option. Now, Rename the file as ‘hello’ (you can change the name as per your convinience.)
