Its 6:50PM in the evening. I started Django yesterday, and as expected problem arrived while I'm in PowerShell for preparing Django. However, I solved it using commands like pip install Django & pip install Django --upgrade(tutorial by code with harry youtube videos), and after that error occurred: pip is not recognized and I again download python from its official website and the error was solved hopefully. After that, I created a folder djangoproject and go to vs code terminal and run a command "django-admin startproject <newfoldername>",  but showed me "django-admin startproject hello django-admin : the term 'django-admin' is not recognized as the name of a cmdlet function script file or operable program. check the spelling of the name or if a path was included verify that the path is correct and try again."   Reason of this error is because of the file path/directory in Powershell.
