To understand what yield does, you must understand what generators are. And before you can understand generators, you must understand iterables. Iterables When you create a list, you can read its items one by one. Reading its items one by one is called iteration: >>> mylist = [1, 2, 3] >>> for i in mylist: … Read more
You did char * response. This makes a pointer variable to a character. Right now it is not pointing to any memory(it is some garbage value). scanf stores user input in consecutive memory addresses starting from the one pointed by response. as response is uninitialised, the input may not necessarily be stored on the stack(Don’t … Read more
Some languages, you showed a python example, support generators that don’t have a return statement, they yield a value on each iteration. In Python, the statement: result = someFunc() makes result refer to a generator object, which you can then use the next() builtin to get the next value. In the Python for loop the … Read more
When asking for code to be reviewed, you should post it here. But regardless of that, there are much more efficient ways to generate a random character. One such way would be to generate a random character between 65 and 90, the decimal values for A-Z on the ASCII table. And then, just cast the … Read more
Well, one reason is that the assignment operator = must have an expression on the right, not a (series of) statement(s). You might then ask why this is so, and I guess it is chosen to limit the complexity of the parser, and to disallow what one might consider confusing code. Note that your toto … Read more
Yes, a generator can’t be equal to a string. When your call your function: get_objects(“anything”), it returns a generator object you can iterate over to get the values. If you want to check if the ith element returned is equal to something, do: for i, elem in enumerate(get_objects(“bla bla”)): if i == 3: return self.assertEqual(elem, … Read more
How does one generate a random number in Apple’s Swift language? check this answer, you can then write an easy function to check your array or data structure for duplicate numbers. 0 solved How to randomly generate numbers that don’t repeat?
You can do this with this code: def generate_matrix(size): “””Generate lists which form an eye matrix””” for i in range(size): # First, we create a new list with size 0s. l = [0] * size # At the specified position, we place a 1. l[i] = 1 # We yield this new list. yield l … Read more
Using php and javascript I created 2 files. call.php – Retrieves a sentence from a database and prints one of them (Random) index.html – A page with a button that runs a function which retrieves a sentence from call.php call.php: <?php $db_host = “localhost”; //Host address (most likely localhost) $db_name = “DATABASE_NAME”; //Name of Database … Read more
I think you need to do something like this # Print out predictions y = regressor.predict(input_fn=lambda: input_fn(prediction_set)) # .predict() returns an iterator; convert to a list and print predictions predictions = list(itertools.islice(y, 6)) print(“Predictions: {}”.format(str(predictions))) I found it from the boston tutorial: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/tutorials/input_fn/boston.py 0 solved Race Condition when reading from generator
//… generate(apple,i); //… you have to specify the arguments in the signature of your function ‘generate’ like: void generate( string apple, int it ) { And the error: size_t i; //… for(i=0; i <= pear.length(); i++) { //logic here?! } you add an element to a string using: string.push_back( ‘a’ ); solved C++ Error: ‘no … Read more
