[Tutor] Problem in terminal

[ayesha narang]

Hello, I am a beginner currently learning how to use python.
I am using Atom- the editor (atom.io <http://atom.io/>), where I have written some programs and saved in a folder.
However, when I try to find this folder in my terminal, it isn’t visible, as seen in the screenshot below. 
Please help me out with this and tell me what the problem is.
Looking forward toy our response.
