I just installed CoolTerm onto my PC. In the command line at the bottom, I typed in

print("Hello World")

And I hit "enter."

It does not execute, and that line of code just disappears. Why is it not printing "Hello World"?

Hitting enter after typing something in the command line will simply send what you typed to the serial port. Unless your serial device sends something back, you won't see any data in the terminal window. If you want to see what you're sending, then you can enable the "Local Echo" option in the Terminal Options in the Connection Options dialog.
