When I first started learning python, I encountered various problems
Cmd command line directory switching instruction:
Open a folder under the current path: cd file name (cd lowercase, there is a space between cd and file name)
Return to the previous directory: cd ..
Return to the root directory: cd/
Opening the python file with the cmd command line window shows that access is denied (the same is true for administrator mode entry) as shown below:
unknown reason
The directory where the file is located->more file name->python file name
