I can't access IDLE in homebrew or python

I tried these two commands but idle does not respond even though both files exist.

/home/linuxbrew/.linuxbrew/bin/idle3.7/
/home/linuxbrew/.linuxbrew/bin/idle3

I can’t save any txt files in the linuxbrew using nemo (yes I am on linux mint 18.) permission denied. but I can open up the interpreter using command line address:
/home/linuxbrew/.linuxbrew/bin/python3.7

I don’t believe either idle nor nemo are packages that can be installed using Homebrew on Linux, so you may be looking for help in the wrong forum. For future posts, please provide the exact command that you ran and the exact copy-and-pasted error message that you saw.
