+
+# Log to console
+dbi.debug(True)
+
+# Log to a file (e.g., log.txt)
+dbi.debug("log.txt")
+
+# stop logging
+dbi.debug(False)
+```
+Calling dbi.debug(True) with boolean True argument will output logs to the console.

+Calling dbi.debug("log.txt") will log messages to the specified file (log.txt in this example).
