for mac (others add your respective path for python) at the top of your python program and from your terminal you can run it just by filename (if it has executable permissions). The next line does exactly that, runs the echo command in our shell through Python.
By default, the process will display all processes by CPU usage, with the process id or PID displayed alongside each entry. if you add a shebang at the start of the python file then you can run a python file by just its name from terminal. To see a list of currently running processes and how much CPU and memory they’re currently using, execute top. which will also run the executable file with its specified shell (if specified in the shebang /bin/ (shell) Right-click on the. Faster is to type sh and a space and then drag the file to the window and release the icon anywhere on the window. This is especially useful for printing a path that you can later copy and paste.

For example, if the helloworld.py file was located in the directory C:/temp, you would type python C. For example, use -C to get a multi-column output, -S to sort by size, -lt to sort by date modified, -la for detailed contents including hidden files, or -lh to create a list with readable file sizes.
