To reset the fill value of the ma, use the ma.MaskedArray.fill_value() method in Python Numpy and set it to None.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or not.NumPy offers comprehensive mathematical functions, random number generators, linear algebra routines, Fourier transforms, and more. It supports a wide range of hardware and computing platforms, and plays well with distributed, GPU, and sparse ... Read More

We can use the locator xpath to identify elements having search text with   or spaces. Let us first examine the html code of a web element having trailing and leading spaces. In the below image, the text JAVA BASICS with tagname strong has spaces as reflected in the html code.If an element has spaces in its text or in the value of any attribute, then to create an xpath for such an element we have to use the normalize-space function. It removes all the trailing and leading spaces from the string. It also removes every new tab or lines ... Read More

To force the mask to hard, use the ma.MaskedArray.soften_mask() method. Whether the mask of a masked array is hard or soft is determined by its hardmask property. The soften_mask() sets hardmask to False.A masked array is the combination of a standard numpy.ndarray and a mask.

After the execution of tests, there are logs generated because of Firefox logging in with geckodriver. This log generation by Firefox can be disabled by certain parameters setting.We can stop these logs from being recorded in the console and capture them in a different file. This is achieved with the help of the System.setProperty method. In the above image, we can see the geckodriver logs generated in the console.SyntaxSystem.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true"); // turning off logs System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, ""); // record logs in another fileExampleimport org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; public class LogsDisable{    public static void main(String[] ...

To compute the differences between consecutive elements of a masked array, use the MaskedArray.ediff1d() method in Python Numpy. The "to_begin" parameter sets the number(s) to prepend at the beginning of the returned differences.This function is the equivalent of numpy.ediff1d that takes masked values into account, see numpy.ediff1d for details.A masked array is the combination of a standard numpy.ndarray and a mask. A mask is either nomask, indicating that no value of the associated array is invalid, or an array of booleans that determines for each element of the associated array whether the value is valid or notStepsAt first, import the ...

A new array from the set of choices is constructed using the np.ma.choose() method. The mode parameter is set to 'wrap'. If mode='wrap', values greater than n-1 are mapped to n-1; and then the new array is constructed.Given an array of integers and a list of n choice arrays, this method will create a new array that merges each of the choice arrays. Where a value in index is i, the new array will have the value that choices[i] contains in the same place.The choices parameter is the choice arrays. The index array and all of the choices should be ... Read More
