import os
import sys
os.execv(sys.executable, ['python'] + sys.argv)

Here is what the above code is Doing:
1. It’s importing the os module.
2. It’s storing the name of the current Python interpreter path in the os.executable variable.
3. It’s constructing a command line using the list data type. The first element in the list is the path to the Python interpreter. The rest of the elements in the list are the arguments to the Python interpreter.
4. It’s executing the command line using the os.execv() function.
5. The Python interpreter exits.
