how to save python file to working directory

[rpdohm]

I am using Bash terminal and my working directory is /home/rpdohm. I am using IDLE to create my python script and when I save my python script (i.e. Test.py) I have no clue where to save it to because it only gives me the standard computer folders such as C:\My Documents, etc. I do not know how to find /home/rpdohm folder to save my python script. I want to run my python script from Bash using the command python3 test.py but of course it cannot find it since it is not in my working directory. I do have the shebang in the first line of python script as well.

I appreciate any help, I recently started learning Python and just in last few weeks have been working with the Bash terminal and have been stuck on this for days....
