Debugger. Data Views

Select this option if you want the PyCharm debugger to automatically evaluate expressions and show the corresponding values in the Variables pane of the Debug tool window.

The debugger analyzes the context near the breakpoint (the current statement, one statement before, and one after). It does so to find various expressions in the source code (if available) such as, for example, myvar.myfield.

If such expressions don't contain explicit method invocations, the debugger evaluates them and shows the corresponding values in the Variables view.

Select this option to display values of variables and expressions in an editor tooltip on mouse hover.

If this option is disabled, you can press Alt to display a value.
