logging vs print

[snippsat]

but I still don't understand the difference. can anyone explain the difference with a real example?

Logging is important in our life.
When you transfer money, there will be logs for the transaction.
When an airplane is flying, the black box will record flight data.
If something goes wrong, people can read the log and get a chance to figure out what happened.
Likewise, logging is also essential for software development.
When a program crashes, if there is no logging record, you have little chance to understand what happened.

Personal many years ago i had a bigger project which had GUI interface and did interactive with web/parsing stuff and several 3 party program.
I had no logging and people send me like 50 lines error message when GUI crash.
Because i had no logging i had to ask them what they did do to get that error message,this is not ideal at all.

Loguru is more enjoyable and it has little boilerplate,and in general much more straight forward to use.
I never use logging in standard library anymore.
Example:

from loguru import logger

logger.remove() # Only info to file
logger.add("file.log", rotation="2 day")

@logger.catch
def user_input(ipt):
    user = int(input("> "))
    logger.info(user)
    while user != ipt:
        print("wrong number!")
        logger.info("wrong number!")
        user = int(input("> "))
        logger.info(user)
    return user

def play():
    user_input(99)

play()

So now also catch Exception(as any string input will break it),just bye adding the decorator.
