Error "variable is not defined", but the variable can be called in the console

Question

I use python on Spyder. My script uses a variable called imgs. I have the following error : name 'imgs' is not defined. But when I try to call imgs in the console, it works, I don't have any error.

Then, I tried to write x=2 in the console of Spyder. Then, I executed a script on spyder (white juste 1 line : print(x)), and I still have the same error : name 'x' is not defined.

I never had this error before

Answer 1

That's because the console can remember recent variables defined in a script, but the script cannot once their gone.

Let me put it this way:

You run a script that imports the math module. Then you go to your script and delete the 'import math' statement.

You will still be able to use the math module without importing it again in the console, as long as you haven't closed the console after you ran the original working script.

Answer 2

You should try running in consoles's namespace Run Preferences
