Hi all, apologies if this has an obvious fix.

I'm working in Spyder 4 and python 3.7.

If I create a variable in a script (for example a = 5), run it, and then 
type a into the console it will give back the value 5.

If I create a variable in the console in the same way and then reference it 
in a script in the editor I get a NameError saying that it hasn't been 
defined.

The same happens if I run a script from the editor twice, the second run 
through is incapable of seeing the variables created on the first run 
(although it can obviously be recreated/defined).

The reason I am trying to work this way is that I am reading in a dataset 
from a spreadsheet, which takes a while, and then creating plots using the 
library Bokeh. Once I've read the data in once I want to be able to keep 
working on the script, making changes and re-running to get all the plots 
working how I like, without having to import all the raw data again but at 
the moment the only way I can reference the data that is shown in the 
variable explorer is through the console.

I'm sure I used to do this in Spyder 3 before I had to get my pc wiped and 
everything re-installed, but I could be wrong about that.

Is there a setting somewhere that I need to change? I've looked in the 
preferences but couldn't see anything that I understood as being related...

Thanks very much for any help,
Lee
