title: My VSCode is unable to run py file with the 'not recognized as the name of a cmdlet' problem
body: <p>I tried to print the &quot;Hello World&quot; in VSCode Terminal and received this message
  <em>&quot;The term 'python' 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.   &quot;</em></p>
  <p>I've already installed python interpreter, adding evironment variables and <strong>WHEN I ATTEMPTED TO RUN MY PYTHON FILE VIA THE COMMAND PROMPT it printed without any problem (including printing lists or performing functions)</strong>.</p>
  <p>I've also checked python in the command and it replies version 3.8.5, however <strong>PowerShell</strong> keeps denying and appear the &quot;not recognized&quot; issue, no matter restarting the computer.</p>
  <p>Can anyone help me with this problem?
  P/s: not only Python files, but my cpp files with C++ programming also have similar problems. I've installed MinGW and the program still can't run.</p>
