💡 Hint

Common Mistakes

Choosing a higher level like ERROR filters out debug messages.

Setting the level to logging.DEBUG captures all messages including debug, info, warning, error, and critical.

💡 Hint

Common Mistakes

Using default or unrelated logger names.

Using "appLogger" names the logger as required.

Fix the error in the code to add a file handler to the logger.

HLD

file_handler = logging.FileHandler([1])
logger.addHandler(file_handler)

Drag options to blanks, or click blank then click option'

Aapp_log.txt

B"app.log"

Capp.log

D"app_log.txt"

💡 Hint

Common Mistakes

Forgetting quotes around the filename causes a NameError.

The filename must be a string, so it needs quotes like "app_log.txt".

4fill in blank

hard

Fill both blanks to format log messages with time and level.

HLD

formatter = logging.Formatter("[1] - [2] - %(message)s")
file_handler.setFormatter(formatter)

Drag options to blanks, or click blank then click option'

A%(asctime)s

B%(levelname)s

C%(message)s

D%(filename)s

💡 Hint

Common Mistakes

Using message or filename instead of time or level in the blanks.

The format includes the timestamp (%(asctime)s) and the log level (%(levelname)s).

5fill in blank

hard

Fill all three blanks to create a dictionary that filters logs with level ERROR or higher.

HLD

error_logs = {k: v for k, v in logs.items() if v['level'] [1] [2] and v['level'] [3] 'CRITICAL'}

Drag options to blanks, or click blank then click option'

A>=

B'ERROR'

C<=

D'WARNING'

💡 Hint

Common Mistakes

Using wrong operators or levels causing wrong filtering.

The filter keeps logs where level is between ERROR and CRITICAL inclusive, so use >= 'ERROR' and <= 'CRITICAL'.
