Run Part of a Script With a Different Version of Python<\/title>\n<\/head>\n<body>\n\n<p>When it comes to running Python scripts, having the right version of Python installed is crucial. However, sometimes you may encounter a situation where you need to run only a specific part of a script with a different version of Python. In this article, we will explore different methods to achieve this.<\/p>\n<div>\n <figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/media.geeksforgeeks.org\/wp-content\/uploads\/20191211200347\/Run-python-script-from-file-GfG.png\" alt=\"Run Part of a Script With a Different Version of Python \"\/><\/figure>\n \n \n <p>Credit: www.geeksforgeeks.org <\/p>\n \n <\/div><div>\n <figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/i0.wp.com\/blog-pantheon-prod.global.ssl.fastly.net\/blog\/wp-content\/uploads\/2020\/07\/Code_Python_Script_Write_Run_Programming.jpg?fit=625%2C391&ssl=1\" alt=\"Run Part of a Script With a Different Version of Python \"\/><\/figure>\n \n \n <p>Credit: generalassemb.ly <\/p>\n \n <\/div><h2>Method 1: Using a Python Version Manager<\/h2>\n<p>One of the easiest ways to run part of a script with a different Python version is by utilizing a version manager such as <a href=\"https:\/\/docs.conda.io\/en\/latest\/\" target=\"_blank\" rel=\"noopener\">conda<\/a> or <a href=\"https:\/\/github.com\/pyenv\/pyenv\" target=\"_blank\" rel=\"noopener\">pyenv<\/a>.<\/p>\n<p>If you have conda installed, you can create a separate environment using the desired Python version with the following command:<\/p>\n<pre><code>conda create -n myenv python=3.7<\/code><\/pre>\n<p>This command will create a new environment named “myenv” with Python version 3.7. You can activate this environment by running:<\/p>\n<pre><code>conda activate myenv<\/code><\/pre>\n<p>Once activated, you can run your script in this specific environment, and it will use the Python version specified.<\/p>\n<p>If you prefer to use pyenv, you can install the desired Python version using the following command:<\/p>\n<pre><code>pyenv install 3.7.0<\/code><\/pre>\n<p>This will install Python version 3.7.0. Then you can create a virtual environment with the specified Python version using:<\/p>\n<pre><code>pyenv virtualenv 3.7.0 myenv<\/code><\/pre>\n<p>Activate the virtual environment:<\/p>\n<pre><code>pyenv activate myenv<\/code><\/pre>\n<p>Now you can run your script within the specified virtual environment, allowing you to utilize the desired Python version.<\/p>\n<div>\n <figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n <iframe loading=\"lazy\" title=\"How to switch Python versions in Windows 10.

You can use this line to specify the desired Python version for a specific part of your script.<\/p>\n<p>For example, if you have Python 3.6 installed and want to run a specific function using Python 3.7, you can add the following Shebang line before the function:<\/p>\n<pre><code>#!\/usr\/bin\/env python3.7<\/code><\/pre>\n<p>By adding this Shebang line, the script will be executed using the specified Python version, even if your default version is different.<\/p>\n<h2>Method 3: Running Part of the Script As a Subprocess<\/h2>\n<p>If you have a more complex scenario where you need to run a specific part of a script with a different Python version and capture or use the output in your main script, you can use the subprocess module.<\/p>\n<p>Here is an example of how you can achieve this:<\/p>\n<pre><code>import subprocess\n\n# Run Python script with a different version\nresult = subprocess.check_output(['python3.7', 'your_script.py'], universal_newlines=True)\n\n# Use the result in your main script\nprint(result)<\/code><\/pre>\n<p>By utilizing the subprocess module, you can execute a separate Python script with a specific version while still capturing and utilizing the output within your main script.<\/p>\n<p>These methods provide you with flexibility when it comes to running part of a script with a different version of Python.
