In my case, I'm using the requests library to call PayPal's API over HTTPS. Unfortunately, I'm getting an error from PayPal, and PayPal support cannot figure out what the error is or what's causing it. They want me to "Please provide the entire request, h...

So what I'm looking for here is something like PHP's print_r function. This is so I can debug my scripts by seeing what's the state of the object in question.

When debugging in PHP, I frequently find it useful to simply stick a var_dump() in my code to show me what a variable is, what its value is, and the same for anything that it contains. What is a good Python equivalent for this?

In Java/C# you can easily step through code to trace what might be going wrong, and IDE's make this process very user friendly. Can you trace through python code in a similar fashion?

Under flask, I want to include/exclude stuff in the jinja template based upon whether, or not, we are in debug mode. I'm not debating if this is a good, or bad, idea (i'd vote 'bad' but want to do it just for this case nonetheless :-), so how might this ...

Is there a way to print a request in flask as a string for debugging purposes? I'd simply like to print all params of a post request without having to write my own formatter for the request object.

When I run tests with ./manage.py test, whatever I send to the standard output through print doesn't show. When tests fail, I see an "stdout" block per failed test, so I guess Django traps it (but doesn't show it when tests pass).

So I'm starting like Python a bit, but I'm having trouble erm...running it. Lol I'm using IDLE for now, but its no use whatsoever because you can only run a couple of lines at a time. I'm also using Komodo Edit to create the actual .py files. My questi...

So, I started learning to code in Python and later Django. The first times it was hard looking at tracebacks and actually figure out what I did wrong and where the syntax error was. Some time has passed now and some way along the way, I guess I got a rout...

I'm trying to use pdb to debug flask application. Setting break point is easy; I just use b index to break when index() is invoked or b 44 to set a break point at line 44. Breakpoint works with b 44 which is the start of the main, but b index doesn't w...

I know that bash -x script.sh will execute script printing each line before actual execution. How to make Perl and Python interpreters do the same?

Maybe easy question but I don't know how to summarize it that I would find my answer. Is it possible to print out all available fields of model? For example in iPython I can import model and just write model name and tab will show all available fields t...

How are you meant to debug errors in Flask? Print to the console? Flash messages to the page? Or is there a more powerful option available to figure out what's happening when something goes wrong?
