What Are Scripts and Modules?
Before we start running Python scripts, let's understand what exactly we're working with. In Python Programming,
- A script is a file containing a series of instructions that tells Python what steps to follow to execute a specific outcome you want. These instructions can be anything from simple arithmetic operations to complex algorithms.
- Modules in Python are like toolkits that have pre-made functions and variables that can be used in your scripts. They help in organizing the code and make it easier to reuse certain functions across different scripts.
Running Python Scripts in Terminal: The Basics
Now, let's talk about how to actually run those Python scripts using the terminal. Think of the terminal as a command center for your computer – it's where you can type in commands to make things happen. Running a Python script in the terminal is like giving your computer a set of instructions written in Python code and asking it to execute them. Below are the steps discussed to run your Python script in a Terminal:
- To start, open up your terminal window. If you're using Windows, you can find it by searching for "Command Prompt" or "PowerShell" in the Start menu. If you're on macOS or Linux, you can usually find it by searching for "Terminal" in your applications.
- Once you've got your terminal open, navigate to the directory where your Python script is located using the cd command. For example, if your script is in a folder called "my_scripts" on your desktop, you'd type cd Desktop/my_scripts and press Enter.
- Now that you're in the right directory, you can run your Python script by typing python script_name.py and pressing Enter. Replace "script_name.py" with the name of your actual Python script file.
And that's it! Your Python script should now run in the terminal, and you'll see any output or results right there in front of you. Easy, right?
How to run a Python script in Linux?
If you're using Linux, running a Python script in Python 3 is quite straightforward. First, open your terminal. Navigate to the directory where your script is located using the cd command. For example:
cd path/to/your/script
python3 script_name.py
Running Python Scripts as Executables
You can also run Python scripts as executables on Unix-like systems. First, add the shebang line at the top of your script:#!/usr/bin/env python3
