Well, I had as well. Honestly, this is not bad. Some print go knock, run the code and see what happens. You definitely need to go rummaging inside output, but you can find the results you want. At least, when you know what you want. But usually not the case, if you know what to test, you may not want to print those exported. Instead, you put some print code to throw you think might have problem areas, then repeated the movement of these statements, you know find the real bug. Is a binary search it! Thankfully, there is a better way. Starting from the Nike Air Jordan 5 Women C language, Nike Air Jordan 5 Women there is a class tool is called the debugger in each language have emerged. Python is no exception, which will have a default debugger. There are some cool community development debugger. In the following pages, I will talk about some of the more popular debugging tools. First, it was built Pdb Python debugger, pdb. It uses a simple command-line interface, there are many when you need them with the debugger functions. Help system can point out to you that you can run a command, such as single-stepping through code, set breakpoints, and call stack manipulation. It lacks some of the features: Press tab allows local variables and let auto-complete code and stack trace look better color and layout. No matter what you finally decide to use a debugger, pdb is worth your time to understand it, there are two reasons: 1) 2) Many other debugger features that are always available in Python is pdb superset pdb allows you to learn faster and learn other debugger. In short, if there is a better or use other debuggers it. Pydbgr followed pydbgr (supports Python 3.2+ version), this project is a rewrite of pydb debugger. It provides a very similar set of pdb command, however, there are some useful aliases such as 'u' represented 'up' is not. The debugger that is capable of doing well for the implementation of fine-grained flow control. You can enter the command and specify the number of times to repeat the command. You can also tell the debugger when certain events Ladies Nike Blazers High Tops Leopard Print Nike Zoom Kobe YellowB trigger stop, such as Air Max 2011 Dark Black Nike Blazers Blue function calls and returns, which allows you to reduce the number of steps for debugging. Another feature of the debugger is the debugger does not Nike Blazers provide additional functionality, such as examine and disassemble it through this very low-level commands Nike Air Max to sign checks. To be honest, I'm not sure this feature proved useful in web development, but it can make your work is very different. In short: I pdb added features I do not think very useful for web development. pudb The debugger highlights the most obvious is that it is in a terminal that incorporates a mini graphical interface. This is correct, this is not a separate window, which is inside the terminal. In addition to a set of default colors used for emphasis (which can Lebron Slide 2 Elite be customized, or select a default set of topics), which is a new attempt on the interactive debugger. The left panel displays the current code file (or you move up and down in a stack of other files). Navigation bar is great, including the arrow keys (and 'hjkl' favorite vim to the masses), search and fuzzy search can open other modules. These simple acts can use a shortcut to combine the implementation of the code at the cursor position, and has a very intuitive and friendly way Air Max 2011 Dark Black Blue to single-step debugger. Of course, pudb still provide normal breakpoints and single-step commands so that you can own way to control the execution of the code. On the right, there are several panels to track the current local variables, stack, and the presence of Nike Mens Nike Free 3.0 V2 Shoes Grey Orange Air Max 2011 Men breakpoints. This is when you type in locals (), whereh or use tab completion to reflect the current framework and a typical terminal debugger is very different, another advantage of this debugger is that it supports post-mortem analysis. When you hit an exception, the debugger will use a quick key to prompt you this exception. It Nike Blazers also allows you to jump directly to the line the exception occurred, while allowing the stack and variable remains intact. Summary: This heap the debugger has the best user experience; especially useful for stack trace. Ipdb last one is iPython Lane ipdb. * Pdb like its brothers, it's interface is a simple command-line help system and it is a very worthy of further study place. Let 2015 Nike Free 5.0 these goods apart is that it uses a iPython shell, so all the tab completion and reflected by the object function are used, can help you discover what happened. These and a great syntax highlighting and formatting where have the best command combined, form the perfect tool to get rid of the bug. Summary: This is the best one is my favorite. I will mention, under the circumstances, I switched to pudb. It really is how to run the code in the browser is the best of terms (such as when you have to study a fault in addition to third-party libraries). And why most tend ipdb, because most of the time I was very familiar with the code, do not need a big picture. I need to know in a specified function in what state. Put them together, something that is super super NB it!like a boss, like debugging Python
