How to make Python 3 as your default “Python Version” on Windows 10/7

Python is a well-known programming language when it comes to solving Data Science related problems. It helps in easing down the work of Data Science with the help of its fast execution of codes because of its built on Object-Oriented Programming but, there is a problem with this language as well. Many Pythonists find it difficult to access the correct Python version because of too many Python versions present in their computer system. Due to this, they face problems in downloading the necessary packages in the correct Python version they want. This leads to many problems in code executions as well as creates confusion for the computer to throw which version at what time.

Now, the question arises on how to resolve this issue and how to add the desired Python version say 3 as the default version on Windows 10/7??

The answer to this question is simple and given below. Just make sure that you have 2 or more than 2 Python versions downloaded in the system to follow these steps of fixing the issue.

Steps to Change the Default Python Version on Windows 10 to Python 3

  • Open your command prompt and check the current Python version the system is using. This will help you get to know which version you are using right now and with which version you want to replace the same.

  • Also, copy the path of the Program Files being present in C Drive.
  • Once the paths are copied the next step is to locate your Environment Variables for the computer. This can be done by right-clicking on the “This PC” option of your computer and clicking on the Properties option. After clicking on the same click on Advanced System Settings under the Properties option.

  • After clicking on the Path option make sure to put the Scripts and Program Files path of different Python versions that you currently want to use and work in, and where you want to store all your necessary packages should be put first followed by others. Simply, click on the Browse button and select the path of the Script folder and the Python3 itself.
  • Note: Remove any other Python Version available in the System variables, for example, Python2. Select its path and click on the Delete button.
  • Press the OK button to save the changes in the Windows’ Environmental Variables.

Add Python 3 directory path in Windows 10 or 7

  • Once this is done, restart your Command prompt and again type python –version. Now you will find the desired version there on the system and ready to be usable by the coder.

Conclusion

This is how a user can get his/her Python version when there are multiple versions on the computer. Try this out and start coding with your desired version.
