for-loop

问题 hi folks i want to access a string variable outside for loop, so that i can use it for further coding. Here i am trying to get the values from Jtable and store it in string, to create a database table. The Whole Code is here: http://textuploader.com/?p=6&id=zVEWY Coding : int row = table.getRowCount(); int column = table.getColumnCount(); for (int j = 0; j < row; j++) { for (int i = 0; i < column; i++) { //System.out.println(table.getValueAt(j, i)); String readstr = (String) table.getValueAt

问题 I am trying to create a list of URLs using a for loop. It prints all the correct URLs, but is not saving them in a list. Ultimately I want to download multiple files using urlretrieve. for i, j in zip(range(0, 17), range(1, 18)): if i < 8 or j < 10: url = "https://Here is a URL/P200{}".format(i) + "-0{}".format(j) + ".xls" print(url) if i == 9 and j == 10: url = "https://Here is a URL/P200{}".format(i) + "-{}".format(j) + ".xls" print(url) if i > 9: if i > 9 or j < 8: url = "https://Here is a

问题 When I use for-loop in my source file, I get a unexpend result. Here is the minimum source file (I hide the head of file and the function of print_set ): // the main function int main(void) { set<int> test{3, 5}; print_set(test); for (auto it = test.begin(); it != test.end();) { auto node = test.extract(it); ++it; } print_set(test); } Then I use command to compile and run: $ g++ --version g++ (Dedian 8.3.0-6) 8.3.0 ... (not very important infomation for this question) $ g++ -std=c++17 temp

问题 I have 10 trials and two conditions (randomized across the trials) that consist of playing either an optic flow mp4 movie or a random flow mp4 movie. To load and play the mp4 I used visual.MovieStim3 nBlocks = 4 nTrials = 10 nb_conditions = np.arange(1,3) # We have two conditions : condition 1 is Optic flow and condition 2 is Random flow conditions = nb_conditions.repeat(nTrials/2) # 5 times condition1 and 5 times condition2 conditions_rand = np.random.permutation(nb_conditions) # Randomize

问题 I'm a super noob, and I'm trying to make a Caesar cipher in p5js, so far I manage to code the UI, but now I'm stuck and don't really know how to move forward can someone please help? I know I need to use for loops, but I can't figure out how? I really appreciate all the help Thanks let inp; let button; let alphabet = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']; function setup() { createCanvas(600, 600); //

问题 I have a data frame with a column of start dates and a column of end dates. I want to check the integrity of the dates by ensuring that the start date is before the end date (i.e. start_date < end_date).I have over 14,000 observations to run through. I have data in the form of: Start End 0 2008-10-01 2008-10-31 1 2006-07-01 2006-12-31 2 2000-05-01 2002-12-31 3 1971-08-01 1973-12-31 4 1969-01-01 1969-12-31 I have added a column to write the result to, even though I just want to highlight

问题 I have 2 tensors, my prediction tensor pred is of shape [batch, rows, cols, depth, vals] or [32, 40, 60, 2, 2] . My ground truth tensor y is shape [batch, num_objs, vals] or [32, 4, 10] . The y tensor has values that correspond to a slice of the pred tensor. I get the indexes using true_grid_coords = (y[:,:,:2] // params.grid_stride) Now I want to create a mask with the same shape as my pred tensor using the vals from true_grid_coords . I want something like [batch, rows, cols, depth, vals] =
