The need for logging frameworks

We now know why logs are important. The next question however is how do we integrate logging capabilities in our application? The simplest and most straightforward way to get your application to log events is to have a bunch of print statements sprinkled in code at the required places. This way, we easily get our event logs to the standard output on our Terminal console, which gets our job done, but there's more to be desired. In quite a few cases, we also want our logs to persist for analysis at a later point in time. So, if we want to collect the output from our print statements to a file, we have to look for additional ways such as piping the output to a file using the shell output redirection facility, which is basically plumbing a different set of tools to get to the goal of getting logs from our application to different outputs. As it turns out, there are limitations to this approach.

You don't get to filter or turn off your print statements for cases...
