A little-known fact about the Python native pickle format is that you can happily concatenate them into a file. That is, simply open a file in append mode and pickle.dump() your dictionary into that file. If you want to be extra fancy, you could do something like timestamped files: def ingest_data(data_dict): filename=”%s.pickles” % date.strftime(‘%Y-%m-%d_%H’) with … Read more
Your problem appears to be only with displaying the results. When selecting from a list, you can either select a certain index, e.g.: print movies_list[0] or a range, e.g.: print movies_list[0:3] print movies_list[3:-1] or you can print the entire list: print movies_list You can’t use commas in the square brackets for lists. solved How do … Read more
This is a math problem, but computers help to solve it using linear forumla (as suggested by @cmgchess in comments): var x1 = 10; var x2 = 100; var y1 = 2; var y2 = 15; var x_inp = 6; // var y_out = ? ? ? var calcY = getLinearFunction(x1, y1, x2, y2); console.log(calcY(6)) … Read more

Try this: for (int i = 1; i <= 14; i++) Console.WriteLine(i – i / 6 – i / 7 – i / 9 + i / 12 – i / 13 + i / 14); At position i = 6, i = 7, i = 9 and i = 13 you want to repeat … Read more
To wrap up this discussion. From @Erresen, “you’re currently catching ALL exceptions with your current catch.” This is fine if you don’t want / need to do something specific based on the specific exception received. However, as @Johny Mopp mentioned, ObjectDisposedException and IOException are potential exceptions. Perhaps, if you have an IOException, you’ll want to … Read more
You could just use explode(“,”,$list_of_emails) and then loop over the resulting array of email addresses to do your sending. You could also probably do this in bash with cut and/or xargs. solved What are C++ arrays in PHP? [closed]
Arrays in C (or C++) are blocks of memory. The compiler needs to know how big the array is in order to allocate the needed amount of memory. They are not expandable. To make an array bigger, you have to allocate a new array with more memory, and copy the old array into it. There … Read more
Try this it will work : function news5($newsarray) { $str=””; foreach($newsarray as $value) { $str.= “<h3>”.$value[‘title’].”</h3>”; } return $str; } echo news5($newsarray); Certain characters have special significance in HTML, and should be represented by HTML entities if they are to preserve their meanings. This function returns a string with these conversions made. If you require … Read more
E_ERROR is defined as 1, so it’s the same as error_reporting(E_ERROR); So basically it tells PHP only to report fatal errors. As Skilldrick says, you should use named constants, as their defined values can and will change through newer versions of PHP. One well-known such example is E_ALL, which had the following values (from the … Read more
Just a quick and dirty script, but this should be what you are looking for… <?php error_reporting(E_ALL | E_STRICT); ini_set(‘display_errors’, 1); /* * Boostrap Magento */ $mageFilename=”../app/Mage.php”; require_once $mageFilename; Mage::setIsDeveloperMode(true); umask(0); $mageRunCode=””; $mageRunType=”store”; Mage::init($mageRunCode, $mageRunType); /* * Set up required data */ $newManufacturers = file(‘manufacturers.txt’, FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES); $newManufacturers = array_unique($newManufacturers); $attribute = Mage::getModel(‘eav/entity_attribute’) ->loadByCode(‘catalog_product’, … Read more
You can define the matrix like so (semicolons can be used for line breaks) A = [1 2 3; 4 5 6; 7 8 0] A = 1 2 3 4 5 6 7 8 0 Then you calculate the determinate by using DET det(A) ans = 27 8 solved MATLAB: how to calculate the … Read more

This program provokes undefined behavior since it does not follow the rules of C. You should give printf one argument per format specifier after the format string. On common C implementations, it prints whatever happens to be on the stack after the pointer to “%d”, interpreted as an integer. On others, it may send demons … Read more
