Shell script not able to access KM folder?

I have Keyboard Maestro save the synced file to (……)/Dropbox/Apps/Keyboard Maestro. (This probably was a bad idea. The "Apps" folder is not good to mess up with).

I have other folders in this folder as well, such as HTML codes, AppleScript, shell script files, etc, that I use with Keyboard Maestro.

Today, I created another folder here named "Python Script" when I run python3 (……)/Dropbox/Apps/Keyboard Maestro/Python Script/abc.py, It says "No such file or directory".

When I move the py file to other folders, such as the Download folder, I was able to execute it successfully.

I'm wondering what the problem is?

Looks like the problem is not with the folder, but with the space in the folder names. If I get rid of the spaces, I can execute the script file.

Using quotation marks has solved the problem.
