To return the next floating-point value after a value towards another value, element-wise., use the numpy.nextafter() method in Python Numpy. The 1st parameter is the value to find the next representable value of. The 2nd parameter is the direction where to look for the next representable value.The function returns the next representable values of x1 in the direction of x2. This is a scalar if both x1 and x2 are scalars.The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated ... Read More
To change the sign of a value to that of another, use the numpy.copysign() method in Python Numpy. The 1st parameter of the copysign() is the value to change the sign of. The 2nd parameter is the sign to be copied to 1st parameter value.The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.The condition is broadcast over the input. ... Read More
To reduce array’s dimension by one, use the np.ufunc.reduce() method in Python Numpy. Here, we have used add.reduce() to reduce it to the addition of all the elements. To initialize the reduction with a different value, use the "initials" parameter.A universal function (or ufunc for short) is a function that operates on ndarrays in an element-byelement fashion, supporting array broadcasting, type casting, and several other standard features. That is, a ufunc is a "vectorized" wrapper for a function that takes a fixed number of specific inputs and produces a fixed number of specific outputsStepsAt first, import the required library −import ...

To compute the truth value of an array OR another array element-wise, use the numpy.logical_or() method in Python Numpy. Return value is either True or False. We have set conditions here as a parameter. Return value is the boolean result of the logical OR operation applied to the elements of x1 and x2; the shape is determined by broadcasting. This is a scalar if both x1 and x2 are scalars.The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array ... Read More
To return the element-wise remainder of division, use the numpy.fmod() method in Python Numpy. For fmod, the sign of result is the sign of the dividend. The fmod() function is equivalent to the Matlab(TM) rem function. Here, the 1st parameter is the Dividend array. The 2nd parameter is the Divisor array.This is the NumPy implementation of the C library function fmod, the remainder has the same sign as the dividend x1. It is equivalent to the Matlab(TM) rem function and should not be confused with the Python modulus operator x1 % x2.The condition is broadcast over the input. At locations ... Read More
Selenium can perform mouse movements, keypress, hovering on an element, drag and drop actions, and so on with the help of the ActionsChains class. We have to create an instance of the ActionChains class which shall hold all actions in a queue.Then the method - perform is invoked which actually performs the tasks in the order in which they are queued. We have to add the statement from selenium.webdriver import ActionChains to work with the ActionChains class.Syntax#Method 1 - chained pattern e =driver.find_element_by_css_selector(".txt") a = ActionChains(driver) a.move_to_element(e).click().perform() #Method 2 - queued actions one after another ...

To compute the truth value of an array AND another array element-wise, use the numpy.logical_and() method in Python Numpy. Return value is either True or False. We have set conditions here.Return value is the Boolean result of the logical AND operation applied to the elements of x1 and x2; the shape is determined by broadcasting. This is a scalar if both x1 and x2 are scalars.The condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that ... Read More
We can locate elements with locator CSS Selector in Selenium webdriver. The general expression to create a CSS expression is tagname[attribute='value']. We can utilize the id and class attributes to create a CSS.With id, the syntax of a CSS expression is tagname#id. For instance, for a CSS expression - input#txt-loc, input is the tagname and the txt-loc is the value of the id attribute.With class name, the syntax of a CSS expression is tagname.class. For instance, for a CSS expression - input.txt-cls, input is the tagname and the txt-cls is the value of the class attribute.If there are n sub-elements(children) ... Read More
