What does the `try` block do in error handling?

The try block in error handling is used to contain code that might potentially raise an exception during execution. This allows the program to attempt to run the code while being prepared to handle any errors that may occur. By placing code within a try block, a developer can manage exceptions gracefully, enabling the program to continue running or to handle the error in a user-defined manner if an exception does indeed occur.

When an exception is raised within the try block, control is transferred to the corresponding except block (if one is provided). This mechanism allows for enhanced robustness in the code, enabling developers to anticipate potential problems and respond to them appropriately, rather than allowing the application to crash or produce unexpected behavior.

The other options refer to different aspects of error handling: one suggests an always-raise condition, another implies guaranteed execution without a focus on exceptions, and the last points to exception capturing without handling—all of which do not accurately describe the primary function of the try block itself.
