Variable not defined even though it is - CoderMerv - Mar-28-2024

Hi! Just started my coding journey and I am immediately running into an error. I am currently reading the book "Python Crash Course: A Hands-on, Project based Introduction to Programming" and am mimicking the examples on VSCode as I read along.

I am currently trying out this example from the book:

message = "hello world"
print(message)
Upon running this in VSCode, I keep getting this error:

Output:
>>> print(message)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'message' is not defined
What am I doing wrong?

Looks like you running python from a cmd line in shell and not the script itself.
either do python script.py or if in the interpreter do message = 'my message' then print(message)

Thank you for this. I figured that I just needed to highlight the entire code, then press shift + enter to run it. Previously, I was only pressing shift + enter without highlighting any line of code. This was effectively running just the last line of code.

you should be able to right click code, select python, and run in terminal
first you need to (one time) press ctrl-P in code window and select interpreter to be used.
