Possible Duplicate:Python Ternary OperatorPutting a simple if-then statement on one line Is there a way to compress an if/else statement to one line in Python?I oftentimes see all sorts of shortcuts and suspect it can apply here too.
You can use df.loc[i], where the row with index i will be what you specify it to be in the dataframe.
The easiest way I found is this: Just open another (non-running, existing) notebook on the same kernel, and the issue is magically gone; you can again save the notebooks that were previously showing the _xsrf error. If you have already closed the Jupyter home page, you can find a link to it on the terminal … Read more
The problem is that you mapped your servlet to /register.html and it expects POST method, because you implemented only doPost() method. So when you open register.html page, it will not open html page with the form but servlet that handles the form data. Alternatively when you submit POST form to non-existing URL, web container will … Read more
In C, the language itself does not determine the representation of certain datatypes. It can vary from machine to machine, on embedded systems the int can be 16 bit wide, though usually it is 32 bit. The only requirement is that short int <= int <= long int by size. Also, there is a recommendation that int should represent the native capacity of the processor. All types … Read more
means: move a literal decimal-10 long (4-bytes) into a 4-byte memory location that begins at the address pointed to by (the esp register plus decimal 24)–basically it is a local variable.
calloc() gives you a zero-initialized buffer, while malloc() leaves the memory uninitialized. For large allocations, most calloc implementations under mainstream OSes will get known-zeroed pages from the OS (e.g. via POSIX mmap(MAP_ANONYMOUS) or Windows VirtualAlloc) so it doesn’t need to write them in user-space. This is how normal malloc gets more pages from the OS as well; calloc just takes advantage of the OS’s guarantee. This means calloc memory … Read more
You get the error because order[1] is undefined. That error message means that somewhere in your code, an attempt is being made to access a property with some name (here it’s “push”), but instead of an object, the base for the reference is actually undefined. Thus, to find the problem, you’d look for code that … Read more
