This notation is closer to os.path.join(), which you may have used in the past. It can feel more familiar than a forward slash if you’re used to backslashed paths.After you’ve instantiated Path, you probably want to do something with your path. For example, maybe you’re aiming ...
In addition, in Python the definition line of an if/else/elif statement, a for or while loop, a function, or a class is ended by a colon. In MATLAB, the colon is not used to end the line. Consider this code example: Python 1num = 10 2 3if num == 10: 4 print("num is eq...
Similarly to global names, nonlocal names can be accessed from inner functions, but not assigned or updated. If you want to modify them, then you need to use a nonlocal statement. With a nonlocal statement, you can define a list of names that are going to be treated as nonlocal....

The error message does a pretty good job here: WebDriver.get_screenshot_as_file() does not have a keyword argument called 'full'. Here is a method I have used in the past: def save_screenshot(): original_size = driver.get_window_size() required_width = driver.execute_script('return...
Implicit conversion of byte sequences to Unicode text is a thing of the past. This chapter deals with Unicode strings, binary sequences, and the encodings used to convert between them.Depending on your Python programming context, a deeper understanding of Unicode may or may not be of vital ...
