The HTML Window moveTo() method moves a window’s left and top edges to the specified coordinates.SyntaxFollowing is the syntax −window.moveTo(x, y)Here, x and y define the value of moving the window horizontally and vertically in pixels respectively.Let us see an example of HTML Window moveTo() Method −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%) no-repeat; text-align: center; } .btn { background: #db133a; border: none; ...

The HTML Window moveBy() method moves the window relative to its current coordinates.SyntaxFollowing is the syntax −window.moveBy(x, y)Here, x and y define the value of moving the window horizontally and vertically in pixels respectively.Let us see an example of HTML Window moveBy() Method −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%) no-repeat; text-align: center; } .btn { background: #db133a; border: none; height: 2rem; ...

The function close() closes an open file. For example: f = open('my_file', 'r+') my_file_data = f.read() f.close() The above code opens 'my_file'in read mode then stores the data it reads from my_file in my_file_data and closes the file. When you open a file, the operating system gives a file handle to read/write the file. You need to close it once you are done using the file. If your program encounters an error and doesn't call f.close(), you didn't release the file. To make sure it doesn't happen, you can use with open(...) as syntax as it automatically closes files regardless of whether ... Read More
The HTML Window pageYOffset property returns the value in pixel the current document has been scrolled vertically from the left corner.SyntaxFollowing is the syntax −window.pageYOffsetLet us see an example of HTML Window pageYOffset Property −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%) no-repeat; text-align: center; } .btn { background: #db133a; border: none; height: 2rem; border-radius: 2px; width: ...

Globals in Python are global to a module, not across all modules. (Unlike C, where a global is the same across all implementation files unless you explicitly make it static.). If you need truly global variables from imported modules, you can set those at an attribute of the module where you're importing it.import module1 module1.a=3On the other hand, if a is shared by a whole lot of modules, put it somewhere else, and have everyone import it:global_module.py module1.py: import global_module def fun(): print global_module.var Other files: import global_module import module1 global_module.var = 3 module1.fun()Read More
The HTML Window screenY property returns the horizontal coordinates of the window relative to the screen. It is supported by all browsers.SyntaxFollowing is the syntax −window.screenYLet us see an example of HTML Window screenY Property −Example Live Demo body { color: #000; height: 100vh; background-color: #8BC6EC; background-image: linear-gradient(135deg, #8BC6EC 0%, #9599E2 100%); text-align: center; } .btn { background: #db133a; border: none; height: 2rem; border-radius: 2px; width: ...

To check if you can import something in Python 2, you can use imp module with try...except. For example, import imp try: imp.find_module('eggs') found = True except ImportError: found = False print foundThis will give you the output:FalseYou can also use iter_modules from the pkgutil module to iterate over all modules to find if specified module exists. For example, from pkgutil import iter_modules def module_exists(module_name): return module_name in (name for loader, name, ispkg in iter_modules()) print module_exists('scrapy')This will give the output:TrueThis is because this module is installed on my PC.Or if you ...

You can use pip to install packages at runtime and importlib.import_module(moduleName) to import module by using its name as a string. For example,import pip import importlib def import_with_auto_install(package): try: return importlib.import_module(package) except ImportError: pip.main(['install', package]) return importlib.import_module(package) # Example if __name__ == '__main__': scrapy = import_with_auto_install('scrapy') print(scrapy)The above script installs the scrapy module and imports it when installation of the module completes.
