PyCharm 2016.1 Help

Debug Tool Window. Watches

In the Watches pane you can evaluate any number of variables or expressions in the context of the current stack frame. The values are updated with each step through the application, and become visible every time the application is suspended.

The Watches pane shows multiple expressions that persist from one debug session to another, until you remove them.

Watch expressions are always evaluated in the context of a stack frame that is currently inspected in the Frames pane. If an expression cannot be evaluated, it is displayed with a question mark.

InspectAvailable for fields, local variables and reference expressions. Choose this command to open the Inspect window for the node, which allows you to perform the same operations as those available in the stack frame, with the only difference that the root node is the one you have selected. You can recursively call the new Inspect windows from within each other. Each window is not modal and immediately reflects all changes in its subtree.
