How to use PyCharm breakpoints for debugging

Breakpoints are a debugging technique that allow programmers to pause a program during code execution and inspect it at specific points. PyCharm provides powerful debugging capabilities, allowing users to easily set and manage breakpoints.

Set a breakpoint

To set a breakpoint:

1. Click to the left of the line number of the line where you want to pause the code.
2. The line will be highlighted blue, indicating that the breakpoint has been set.

Activate breakpoint

After setting a breakpoint, it will be inactive. To activate a breakpoint, click the breakpoint marker or press Alt F9 (Option F9 for macOS).

Disable Breakpoint

To disable a breakpoint, click the breakpoint marker or select Run > Toggle Breakpoint. This will cause PyCharm to ignore the breakpoint and continue program execution.

Conditional Breakpoints

PyCharm allows the creation of conditional breakpoints, which only trigger when specific conditions are met. To create a conditional breakpoint:

1. Set a regular breakpoint.
2. Right-click the breakpoint marker and select Edit Breakpoint.
3. Under the Conditions tab, enter the conditions that trigger the breakpoint.

Advanced breakpoint options

PyCharm provides the following advanced breakpoint options:

• Line breakpoints: Pause the program at a specific line.
• Function breakpoint: Pause the program while the function is executing.
• Exception breakpoints: Pause the program when a specific exception is thrown.
• Data breakpoints: Pause the program when a variable or expression changes.
• Smart breakpoint: Pause the program when the program state changes.
• Tag breakpoints: Allows filtering breakpoints based on tags.

Debugging with breakpoints

After setting breakpoints, you can use PyCharm’s debugger to:

• Check variables: View the value of the variable at the breakpoint and modify it.
• Step-by-step execution: Execute the code line by line and observe its behavior.
• Call stack: View the currently executed function calls.
• Exception handling: Diagnose and repair exceptions.

By using PyCharm's breakpoint debugging feature, you can easily identify and solve problems in your code, speeding up the development process and improving code quality.
