Python Was Not Found Windows 10

Python is a widely used programming language known for its versatility and ease of use. However, some users encounter the frustrating issue of Python not being found on their Windows 10 system. This unexpected hiccup can hinder productivity and leave users searching for solutions.

To understand the root cause of Python not being found on Windows 10, let's delve into its history. Python was first released in 1991 by Guido van Rossum and has since gained popularity due to its simplicity and extensive libraries. Today, Python is used for various applications ranging from web development to scientific computing. Despite its widespread usage, Windows 10 users sometimes face the perplexing situation of Python not being found, which can be attributed to several factors like incorrect installation or misconfiguration.

Troubleshooting Python Not Found Error on Windows 10

Python is a popular programming language used for a wide range of applications. However, sometimes users encounter an error message stating "Python was not found" on their Windows 10 systems. This error can be frustrating and may prevent users from running Python scripts or executing Python-related commands. In this article, we will explore the possible causes of this error and provide troubleshooting steps to resolve it.

Cause 1: Python Not Installed

The most common cause of the "Python was not found" error on Windows 10 is that Python is not installed on the system. Python needs to be installed before it can be used to run scripts or execute commands. To check if Python is installed, follow these steps:

• Open the Command Prompt by searching for "cmd" in the Windows Start menu.
• Type "python" and press Enter.
• If Python is installed, the version information will be displayed. If Python is not installed, you will see an error message stating that "python" is not recognized as an internal or external command.

If Python is not installed, you will need to download and install Python on your Windows 10 system. Visit the official Python website at python.org/downloads and download the latest version of Python for Windows. Run the installer and follow the on-screen instructions to complete the installation.

After installing Python, open the Command Prompt again and type "python" to verify that Python is now recognized as a command.

Cause 2: Incorrect Path Environment Variable

The second common cause of the "Python was not found" error is an incorrect or missing entry in the system's Path environment variable. The Path variable is a system variable that specifies the directories where executable files are located.

To check the Path variable for Python, follow these steps:

• Right-click on the Windows Start button and select "System".
• In the System window, click on "Advanced system settings" on the left-hand side.
• In the System Properties window, click on the "Environment Variables" button.
• In the Environment Variables window, scroll down to the "System variables" section and look for the "Path" variable.
• Click on the "Path" variable and then click on the "Edit" button.

In the Edit Environment Variable window, you should see a list of directories separated by semicolons. One of these directories should be the location of the Python executable (e.g., C:\PythonXX\). If the Python directory is missing, you will need to add it:

Click on the "New" button and enter the path to the Python directory. Make sure to use the correct version number in the path.

After adding the Python directory to the Path variable, click "OK" on all the windows to save the changes. Open a new Command Prompt window and type "python" to check if the error has been resolved.

Cause 3: Python Installation Directory Name

In some cases, the "Python was not found" error may occur if the installation directory name contains spaces or special characters. The installation directory should be a simple path without any special characters or spaces.

To resolve this issue:

• Uninstall Python from your Windows 10 system
• Download the Python installer again from the official website
• During the installation, choose a simple and straightforward directory name without spaces or special characters
• Complete the installation and check if the error message persists

Additional Tips

If you encounter the "Python was not found" error even after following the troubleshooting steps mentioned above, consider the following additional tips:

• Restart your computer after making any changes to the system's environment variables.
• Ensure that you have the necessary permissions to modify the Path variable and install software on your Windows 10 system.
• If using a Python distribution such as Anaconda or Miniconda, refer to their documentation for specific troubleshooting steps.

Troubleshooting Python Not Found Error on Windows 10 (Continued)

Continuing from the previous section, let's explore some additional causes and troubleshooting steps for the "Python was not found" error on Windows 10.

Cause 4: Incorrect Python Version

Another potential cause of the "Python was not found" error is using an incorrect version of Python. If you installed multiple versions of Python on your Windows 10 system, there might be a conflict.

To check the installed Python versions, follow these steps:

• Open the Command Prompt by searching for "cmd" in the Windows Start menu.
• Type "python --version" and press Enter.
• The output will show the currently installed Python version.

If you have multiple Python versions installed, you can specify the desired version in the command by using the version number or the full path to the executable. For example:

• Type "python3 --version" or "python3" to use Python 3.x.
• Type "python2 --version" or "python2" to use Python 2.x.
• Type the full path to the Python executable (e.g., "C:\Python37\python.exe") to use a specific version.

Make sure to update your scripts and commands accordingly to use the correct Python version.

Cause 5: Anti-virus or Security Software

In some cases, anti-virus or security software can interfere with the execution of Python scripts and commands, leading to the "Python was not found" error. Anti-virus software may flag certain Python files as potentially harmful or block their execution.

To troubleshoot this issue:

• Temporarily disable your anti-virus or security software.
• Run your Python scripts or commands.
• If the error does not occur while the software is disabled, you may need to add exceptions or exclusions to your anti-virus or security software to allow Python to run.

Refer to your anti-virus or security software documentation for instructions on adding exceptions.

Cause 6: Corrupted Python Installation

In rare cases, the "Python was not found" error may be caused by a corrupted Python installation. If none of the previous troubleshooting steps resolve the issue, it might be necessary to uninstall Python completely and reinstall it.

To uninstall Python:

• Open the Control Panel on your Windows 10 system.
• Click on "Programs" or "Programs and Features".
• Locate Python in the list of installed programs.
• Right-click on Python and select "Uninstall" or "Remove".
• Follow the on-screen prompts to uninstall Python.

After uninstalling Python, restart your computer and perform a fresh installation of Python by following the steps outlined in the first section of this article. This should resolve any issues related to a corrupted installation.

In conclusion, encountering the "Python was not found" error on Windows 10 can be frustrating, but with the troubleshooting steps provided in this article, you should be able to identify and resolve the underlying causes. Remember to check if Python is installed, verify the Path environment variable, ensure a correct installation directory name, check for incorrect Python versions, consider anti-virus or security software interference, and address any potential issues with a corrupted Python installation. By following these steps, you can overcome the "Python was not found" error and continue using Python for your programming needs.
