First you need to install virtualenv library:

pip3 install virtualenv

After installing virtualenv, now create virtual environment directory with any name:

virtualenv myvenv

Now you can see, myvenv folder. now you can activate the virtual environment using that folder location:

.\myvenv\Scripts\activate.bat

Now you can see the virtual environment activated and you can see (myvenv) on your command prompt.
I wish to use Django to create a Web app, but first I need to create an virtual environment.
Since I have a Windows system, I have used Win+R and cmd to open the teriminal, then the system shows C:\Users\HP>, I tried to create a datalog named learning_log and use terminal to switch to this datalog, so I typed in learning_log$ python -m venv 11_env, but the system shows 'learning_log$' is not recognized as an internal or external command,
operable program or batch file.
May I know how to create a datalog and how to create an virtual working environment?
