   To set a breakpoint, merely click on within the gutter (the world to the left of the road numbers) of the Python file the place you need the execution to pause. A pink circle will seem, indicating the breakpoint.

   For instance, if in case you have a line like: consequence = calculate_sum(a, b), and you believe you studied a problem within the calculate_sum operate, you would set a breakpoint on that line to examine the values of a and b earlier than the operate is known as.

2. Beginning the Debugger:

   After setting your breakpoints, begin the debugger by right-clicking in your Python script within the mission view and choosing “Debug” or by clicking the debug icon within the toolbar (often a bug icon). It’s also possible to configure a debug configuration to specify the script to run and any arguments.

3. Stepping By Code:

   As soon as the debugger hits a breakpoint, the execution will pause. You may then use the step controls to maneuver via your code:

   • Step Over (F8): Executes the present line and strikes to the subsequent line within the present operate. If the present line calls one other operate, your complete operate name is executed as a single step.
   • Step Into (F7): If the present line calls a operate, this command steps into the operate, permitting you to look at the code inside that operate.
   • Step Out (Shift + F8): Executes the remaining code within the present operate and returns to the calling operate.

   Through the use of these step controls along side breakpoints, you possibly can fastidiously hint the execution of your code, analyzing the values of variables at every step.

   As an illustration, think about you’re debugging a loop that calculates the sum of an inventory of numbers. You may set a breakpoint contained in the loop, step via every iteration utilizing “Step Over,” and observe how the sum variable adjustments with every step. This lets you establish if the loop is performing the calculations as anticipated or if there are any points with the loop situation or the calculation itself.
