Attribute .context_use_ps1 is False in EditorWindow and Outwin, True in PyShell. It is use to switch code paths in multiple classes. It is equal to isinstance(self/editwin, PyShell) (which requires an import). It has the same truth value as attribute .prompt_last_line, which is '' except in PyShell. This more informative attribute was added in #31858 to consolidate all PS1 handling in PyShell.
A PR for #34055 proposed to remove the setting of .context_use_ps1 and the uses with .prompt_last_line. I will change the title after I submit this. I am not yet sure if this is the change I want to make. |
