# Use the default console logger
console.info("Hello World!")
console.success("Task completed")
console.warning("Low disk space")
console.error("Connection failed")
console.debug("Variable x = 42")

# Create a named logger
logger = Logger(name="MyApp")
logger.info("Custom logger message")

2. Error Logging with Exception Details

from xylogger import console

try:
    result = 1 / 0
except Exception as e:
    console.error("Division failed", error=e)

# Output:
# [-(12:30:45)-] [ ● ] ERROR  »  Division failed
#             └──> [ZeroDivisionError] division by zero
