print does not open console in Linux Mint [Solved]

[Tycho_2025]

Dear forum members,

I use Linux Mint Cinnamon 22.2 with Python 3.12.3
I have this simple script myscripy.py:

#!/usr/bin/python
print('Hello World!')
input('press enter to exit')

The file is executable.

I would like to run the scrip by double clicking, like I would in windows.
What I would like to happen if I double click the file:
a console opens and the text 'Hello World!' and 'press enter to exit' appears.

The program runs, but the console does not open, so I can't see the ouput of a print command.

I tried several things:

If I create a launcher with the command
$ python3 ./myscript.py
the console does not open.

If I run the script from the terminal
$ python3 ./myscript.py
the console opens with the text.

If I run the script from Visual Studio Code, the console also opens showing the text.

But I prefer to double click.

When I googled I found posts suggesting the st.out buffer needs to be flushed.
So I tried to use header

 #!/usr/bin/python -u

And I also tried to use

print('Hello World!', flush=True)

but still the console does not open.

Does anyone has a suggestion?

Why should your code open a console?

run it with

gnome-terminal -- /path/to/myscript.py

or to start with double click, create a launcher

#!/bin/sh
gnome-terminal -- /path/to/myscript.py

Or like this in bash: First write python3, then space, then your programme name. In my case, the file hello_world.py is in my cwd, general_things

peterr@peterr-Modern-15-B7M:~/PVE/general_things$ python3 hello_world.py
Hi cruel world!

Thank you Axel.

If the console or terminal does not open, I can't see the ouput of a print command.

Meanwhile I found a similar solution as you posted:
-right click on my_script.py
-open with --> other application
-in the open field give the command
gnome-terminal -e '/usr/bin/python3 %F'
-click 'Set as Default'
-click 'Ok'

In this way a .py file always runs AND you can see the output of a print command
(and without having to create a launcher or a separate bash file).

-e is deprecated

--command, -e=COMMAND
Split the argument to this option into a program and arguments in the same way a shell would, and
execute the resulting command-line inside the terminal.

This option is deprecated. Instead, use -- to terminate the options, and put the program and
arguments to execute after it: for example, instead of gnome-terminal -e "python3 -q", prefer to use
gnome-terminal -- python3 -q.

Note that the COMMAND is not run via a shell: it is split into words and executed as a program. If
shell syntax is required, use the form gnome-terminal -- sh -c '...'.

Thank you, Axel, I also noticed the warning that -e is deprecated.
I will try your solution.
I also did some research and found:
gnome-terminal -- bash -c "/usr/bin/python3 %F; bash"
