![]() Once the post-mortem debugger kicks in, we can inspect all of the variables in the current frame and even run new code to help us figure out what's wrong and attempt to make a fix. Running 'cont' or 'step' will restart the program Let's try post-mortem debugging this error: $ python3 -mpdb script.pyįile "/usr/lib/python3.4/pdb.py", line 1661, in mainįile "/usr/lib/python3.4/pdb.py", line 1542, in _runscriptįile "/usr/lib/python3.4/bdb.py", line 431, in run Try running it normally and you will see one of the bugs: $ python3 script.py We're expecting the program to do some basic math operations on random numbers in a loop and print the result. To see how these basic debugging steps work, I'll be using this (buggy) program: import random From here, you can run Python code and debugger commands at the prompt to inspect the current program state. If the program throws an unhandled exception, you'll also see a (Pdb) prompt, but with the program execution stopped at the line that threw the exception. At this point, you can use quit / q or Ctrl+D to exit the debugger. If the program executes successfully, you will be taken back to the (Pdb) prompt where you can restart the execution again. To start execution, you use the continue or c command. ![]() ![]() You can run an existing script with the post-mortem debugger by using Python's -mpdb option: python3 -mpdb path/to/script.pyįrom here, you are dropped into a (Pdb) prompt. After that, you attempt to make a fix and repeat the process until the problem is resolved. This is where you run your program as usual, but whenever an unhandled exception is thrown, you drop down into the debugger to poke around in the program state. The first workflow I used after moving away from print debugging was pdb's "post-mortem debugging" mode. modules installed from PyPI) and the standard library. Once you get good at this, it means more time spent diving into issues and less time context switching back and forth between your editor and the command line.Īlso, by not touching the underlying source code, you will have the ability to step into third party code (e.g. With pdb, you have a lot more flexibility to run, resume, and alter the execution of your program without touching the underlying source. interactive debuggingįirst, why would you want to use an interactive debugger instead of inserting print or logging statements into your code? In this post I will show you a few tips I've picked up over the years to level up my interactive debugging skills. For a long time, I stuck to basic print-debugging and used pdb on a limited basis, which meant I missed out on a lot of features that would have made debugging faster and easier. Python's built-in pdb module is extremely useful for interactive debugging, but has a bit of a learning curve.

Reverse the movement by bending your elbows and slowly pulling the dumbbells back to hover just above your pecs.Squeeze your chest muscles to extend your arms until the dumbbells are directly above your upper chest. Retract your shoulder blades and brace your abdominals by taking a deep inhale. Hold the dumbbells with an overhand grip just above your chest.Lay down on the bench and firmly plant your feet for support and stability. Adjust a bench so that it is at a 30-degree incline.When pressing with dumbbells, the weight moves up and inward, moving the chest muscles through a fuller range of motion. They activate the same muscle groups but are more comfortable for some lifters as they allow more natural wrist and shoulder movement. Incline dumbbell presses are the closest alternative to standard incline barbell bench presses.

TikTok – an app for sharing short videos – is used by 21% of Americans, while 13% say they use the neighborhood-focused platform Nextdoor.Įven as other platforms do not nearly match the overall reach of YouTube or Facebook, there are certain sites or apps, most notably Instagram, Snapchat and TikTok, that have an especially strong following among young adults. One-quarter say they use Snapchat, and similar shares report being users of Twitter or WhatsApp. When it comes to the other platforms in the survey, 40% of adults say they ever use Instagram and about three-in-ten report using Pinterest or LinkedIn. And YouTube and Reddit were the only two platforms measured that saw statistically significant growth since 2019, when the Center last polled on this topic via a phone survey. YouTube and Facebook continue to dominate the online landscape, with 81% and 69%, respectively, reporting ever using these sites. adults.īeyond the general question of overall social media use, the survey also covers use of individual sites and apps. ![]() Here are the questions used for this report, along with responses, and its methodology.ĭespite a string of controversies and the public’s relatively negative sentiments about aspects of social media, roughly seven-in-ten Americans say they ever use any kind of social media site – a share that has remained relatively stable over the past five years, according to a new Pew Research Center survey of U.S. adult population by gender, race, ethnicity, education and other categories.
