How to perform breakpoint debugging in pycharm

PyCharm provides breakpoint debugging capabilities to effectively debug Python code, allowing execution to be paused at specific lines of code to inspect variable values ​​and step through code. Set breakpoints: Set red dots on lines of code. Manage breakpoints: Edit, delete or disable breakpoints. Temporary breakpoint: only valid in the current debugging session. Conditional breakpoint: Trigger a break based on conditions. Debugging process: run to breakpoints, step through, step into, inspect values ​​and view stack traces. Tip: Use the breakpoint manager, conditional breakpoints, step-through, and variable inspection to gain deeper insight into code behavior.

PyCharm Breakpoint Debugging Guide

In order to effectively debug Python code, PyCharm provides powerful breakpoint debugging Function. Breakpoints allow you to pause execution at specific lines of code to examine variable values, review stack traces, and step through code.

How to set a breakpoint:

• Place the cursor at the line of code where you want to set a breakpoint.
• Press the F9 key or right-click the line of code and select "Toggle Breakpoint".
• A red dot will appear on the left edge of the line of code, indicating that a breakpoint has been set.

Manage breakpoints:

• Edit breakpoints:Click "Edit Breakpoints" in the "Debug" toolbar " button, or press Ctrl Shift F8. This will open the "Breakpoints" window where you can edit, delete, or disable breakpoints.
• Temporary breakpoints: Temporary breakpoints can be set by right-clicking on a line of code and selecting "Add Temporary Breakpoint". It is only valid within the current debugging session.
• Conditional breakpoints: By selecting the "Conditional" tab in the "Breakpoints" window, you can set a conditional breakpoint that only triggers when specific conditions are met.

Debugging process:

• Run to breakpoint: Press F5 key or click The "Run" button on the toolbar runs the code. Execution continues until a breakpoint is encountered.
• Step by step execution: Press the F11 key or click the "Step Into" button on the "Debug" toolbar to execute the code step by step. This will execute the code line by line, allowing you to see changes in variable values.
• Step by step: Press the F7 key or click the "Step Over" button on the "Debug" toolbar to step into the function. This will execute the function without executing it line by line.
• Check the value: At a breakpoint, you can use the "Variables" window to check the value of a variable.
• View Stack Trace: The "Stack" button on the "Debug" toolbar allows you to view the current stack trace. It shows the functions called during execution.

Tips:

• Use the Breakpoint Manager to easily manage multiple breakpoints.
• Set conditional breakpoints to interrupt execution only under specific conditions.
• Use step-by-step and step-in to get a deeper understanding of code behavior.
• View variable values ​​and stack traces to better understand the debugging process.
