That's a console alias [1], which gets evaluated by the console host process (conhost.exe) when the target process does a normal read via ReadConsoleW or ReadFile. By default doskey.exe creates an alias for "cmd.exe" processes. In the above case, if you enter a line in CMD's prompt that starts with "python3" (ignoring initial whitespace), CMD will instead read "f:\ProgramFiles\Python36\python.exe" from the console input buffer. There are obvious limitations. Since it matches at the start of a line of input, we can't pipe to an alias; or run it on the right-hand side of the &, &&, or || operators; or use it as a command in a `FOR /f` loop; or control how it executes via the START command. Also, since it's only implemented for reads from the current console, it can't be used as a command in a batch script, i.e. CMD will read "python3" from the batch file, not "f:\ProgramFiles\Python36\python.exe".
