Transcrypt is a powerful tool that allows developers to compile Python code into JavaScript. It’s an excellent resource because it enables you to use Python syntax and libraries to write client-side code for a web application. In this tutorial, you will learn how to use it with your Python code.
Step 1: Ensure You Have the Necessary Software
Before we start, you will need to have Python 3.x and pip (Python package manager) installed on your machine. If you do not have these installed, you can check out this link to download Python and this link for pip installation guidelines.
Step 2: Install Transcrypt
Now you can install Transcrypt. Use pip to install it by typing the command:
|
1 |
pip install transcrypt |
Step 3: Create a Python File
The next step is to create a Python file. You can name it ‘test.py’. For testing purposes, we are writing a simple print statement in the Python file:
|
1 |
print('Hello, World!') |
Step 4: Compile Python to JavaScript
Open your terminal, navigate to the directory where you’ve saved your ‘test.py’ file, and compile it to JavaScript with Transcrypt by typing the command:
|
1 |
transcrypt -b -m -n test.py |
This command generates several files. The important one is the JavaScript file named ‘test.js’.
Step 5: Verify the Output
You can navigate to the ‘__target__’ directory. There, you will find the ‘test.js’ file. Open it to verify that the transcrypt has compiled your Python code into JavaScript accurately:
|
1 |
console.log ('Hello, World!'); |
Code:
|
1 2 3 |
# create a file test.py print('Hello, World!') #compile to JS |
Write this in the command line:
|
1 |
transcrypt -b -m -n test.py |
This is the “__target__” directory with the contents:
Conclusion
So, there you have it, a step-by-step guide on how to compile Python code into JavaScript using Transcrypt. This tool can be an invaluable addition to your development toolbox, especially if you’re a Python developer eager to venture into the world of web development.
