Can python file be executed in Command Prompt regardless the drive where you installed Python program?

Question

if I installed Python program in my E drive not C drive, is it the necessary that I must execute python files in the same drive that I installed python program in Command Prompt?

for example, I installed Python Program in my E drive. I can only be allowed to execute python files by following command?

E:\python34\python filename.py

NOT

C:\python34\python filename.py

or

E:\others_direactory\python filename.py

so, I always need to tell computer to use Python program to execute the python.py, otherwise it will alert "XXX is not recognized as an internal or external command, operable program or batch file".

is that right?

Thanks

If you add `E:\python34` to your system path, you could run the command as `python filename.py` — Jake Griffin, May 27 '15 at 22:50
After adding that, so I should be able to run like E:\python filename.py directly? @JakeGriffin — Yu Xiong, May 27 '15 at 23:04
but in my Command Prompt it always start with C:\>User\Xiongyu> @JakeGriffin — Yu Xiong, May 28 '15 at 09:09

This is not an issue with the Python Path, it is an issue with the System Path – Jake Griffin May 27 '15 at 22:55

Yes, you always have to tell the computer to use the python executable to execute python programs. It does not matter if you install to C: or E: drive either, you just always have to start out by specifying python executable. The program you are running is just an argument passed to it.

You can make it less of a pain by doing what @jake-griffin suggested and adding the location to your system Path variable so you only have to type python instead of the whole path to it.
