I have to set environmental variable in my windows PC as follows:
variable name: GISBASE

Is it possible to set it from python?
Which Python? I'll have to assume 3.x
import sys
sys.path.append("C:\\GRASS-64")
But how to give variable name? I have to set both the variable name and
value.
sys.path has nothing to do with an environment variable of GISBASE.
Instead you could look up os.environ at:
https://docs.python.org/3/library/os.html
Also see os.getenv and os.setenv.
Note that it's not necessarily supported. But I believe it is for a
standard build on Windows.
Next question is what you hope to achieve by setting such a variable.
You do realize that it will vanish again when your python process ends?
So if you're just planning to use it in your own code, I'd recommend
finding another method of saving the name & value.
The only value I can see is if you plan to create a subprocess from your
Python code.
