Python path in command prompt

Question

I had Python3 installed on my computer after Python2. Then I executed "python" in command prompt, Python3 showed up. How does the command prompt find Python without specifying the path? Can I switch it back to Python2 without reinstalling?

What OS do you use?

If you are on windows you need the python27 to be first in your PATH enviroment variable

PATH=c:\python27;otherstuff...;c:\python35;...;

or just write

py -2

To start python2

Please note that there is no mention of Python2.7 in OPs post, nor does python have to be installed in the root of drive C.
