By default in Spyder4 Scripts run scripts in a new empty namespace and append the results to the console namespace. This was done to prevent difficult to detect bugs among new Spyder users. There is an option on the run configuration per file dialog to run a file in the current namespace. This option can also be set universally in the general preferences.
I think that using code cells is a great way to use this type of work flow where you want to run a longer subroutine and run code against it later. This plays nicely with the code error checking as well. https://docs.spyder-ide.org/editor.html#defining-code-cells On Thursday, November 7, 2019 at 3:28:46 PM UTC-7, Rational-IM wrote: > > > This is a fantastic upgrade - the new dark format is a great addition.
