Running Brackets code

[Jojogeno]

I am new to python, just installed today and have been playing around with brackets and Python. I am confused on how to get my code from brackets to run in python. My code in brackets was saved as print("happy to be here") and I saved it as happy.py. any help is greatly appreciated! Thank you!

Well, get started right!

First look up: Setting up a Python Virtual Environment. Lots of info out there. Profis will set up a Virtual Environment for each new project, I believe.

snippsat, a moderator and very experienced programmer here recommends a tool called uv for this task.

The uv docs. Read this, then you will know how to set up your Virtual Environment.

I don't know if you use Windows or Linux. In Linux we have a terminal called bash, you can do things from the command line.

To run a Python programme in bash, not in an IDE, you must have the shebang as the first line, like this: #! /usr/bin/python3 Not sure what that looks like in Windows, I almost never use Win.

#! /usr/bin/python3
print("Hello cruel world!")

If I save this as happy.py in my Virtual Environment, I can run it in a bash terminal like this:

(This is what I see in my bash terminal. GPE is my Python Virtual Environment)

Output:
(GPE) peterr@peterr-Modern-15-B7M:~/PVE$ python happy.py
Hello cruel world!
(GPE) peterr@peterr-Modern-15-B7M:~/PVE$ 

Once you have your Virtual Environment, you can start it like this in a bash terminal:

peterr@peterr-Modern-15-B7M:~/PVE$ cd PVE && source GPE/bin/activate && python3 -m idlelib.idle

My Virtual Environment is in a folder called PVE and is called GPE. You need to put your own Virtual Environment path and name in this.

This will start Idle, which is a free IDE that comes with Python. At least for beginners, Idle is OK. The profis here prefer other IDEs I think!

If you run into problems getting set up, ask here, I'm sure people will be glad to help. don't forget to read the docs!

A couple of things:
1. Don't post images, copy/paste as text and format using proper BBCode tags
2. Learn about different ways to execute python code.
Basically:

Output:
>>>

means you are in Python interactive shell, i.e. execute python code line by line as you enter it.
You cannot execute shell/OS commands. They are executed in cmd/shell (that is when you have something lile C:\>
to exit from python interactive mode use exit()
e.g.

Output:
C:\Users\JohnDoe>python  <--here you are in cmd shell and start python in interactive mode
Python 3.12.0 (tags/v3.12.0:0fb18b0, Oct  2 2023, 12:49:59) [MSC v.1935 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> name = input("what is your name? ")
what is your name? John
>>> print(f'hello {name}')
hello John
>>> exit() <--exit from python back to cmd shell

C:\Users\JohnDoe>cd C:\Users  <-- execute OS command
C:\Users>python happy.py <--run your happy.py, assuming it is located in c:\Users folder
