Run Python script online

I'd be happy to help you with that!

To run a Python script online, we can use platforms like Repl.it, Google Colab, or CodePen. These platforms provide an environment for us to write and execute our code in the cloud.

Let's go with Repl.it, as it's free, easy to use, and has a vast library of languages including Python!

Here's how you can get started:

Go to Repl.it (www.repl.it) and sign up for an account. Click on the "New Repl" button and select Python from the list of available languages. You'll be taken to a code editor where you can start writing your Python script!

Here's a simple example:

# This is a comment - anything after the "#" symbol is ignored

print("Hello, World!")

name = input("What's your name? ")

age = int(input("How old are you? "))

print(f"Hi {name}, you're {age} years old!")

for i in range(5):

print(i)

In this example, we:

Print a message saying "Hello, World!". Ask the user for their name and age using input functions. Print out a personalized greeting based on the user's inputs. Loop 5 times using a for loop.

When you run this script, it'll ask you to enter your name and age. It will then print out your personalized greeting and execute the loop!

Some popular Repl.it features include:

Automatic code completion: Repl.it will suggest possible completions based on your code. Real-time error detection: If there's an error in your code, Repl.it will highlight it for you! Collaborative editing: You can invite others to edit your repls and work together.

Repl.it also has a vast library of pre-made templates and examples that you can use as starting points. It's perfect for beginners or those looking to quickly prototype ideas!

How do I run Python from command prompt?

I'll respond in English, but don't worry, grandma won't get too upset .

To run Python from the Command Prompt (or Terminal on Mac/Linux), follow these steps:

Check if Python is installed: Open your Command Prompt or Terminal window and type python --version. If you see a version number printed out, it means Python is already installed on your system. If not installed: Download and install Python from the official website https://www.python.org/downloads/. Follow the installation instructions to set up Python on your machine.

Running Python from the Command Prompt

Open your Command Prompt or Terminal window. Type python (without quotes) to start a new Python session. You'll see a (Pdb) prompt, which indicates you're in interactive mode. If you want to run a specific Python script or program, type the name of the file followed by .py, and press Enter. For example: myprogram.py. This will execute the Python code contained in that file.

Some basic commands to get started

To exit Python and return to the Command Prompt, type exit() (without quotes) and press Enter. To enter into an interactive Python session again, just type python (without quotes) and press Enter. To run a specific Python script without entering the interactive mode, use the -c option followed by the name of the file. For example: python -c myprogram.py.

Tips and Variations

Shebang: If you're on a Unix-based system (like Linux or Mac), you can add a shebang line (#!/usr/bin/env python) at the top of your Python script to make it executable. This way, you can run your Python script directly from the Command Prompt using ./myprogram.py (assuming the file is in the current directory). Python interpreter: When running Python from the Command Prompt, you can also specify a specific interpreter version by providing the full path to the Python executable. For example: C:Python39binpython.exe myprogram.py. Command-line arguments: You can pass command-line arguments to your Python script using the - option followed by the argument name and value. For example: python -a 1234 myprogram.py.

That's it! With these steps, you should be able to run Python from the Command Prompt or Terminal on Mac/Linux. Happy coding !
