If you would rather not download any additional software, there’s a good chance that some of the apps you have laying around can indeed record your screen, even if that’s not their primary purpose. Here are several apps that you probably have access to right now, and how they can record for you. PowerPoint Didn’t know you can record your screen with PowerPoint, the presentation software included with Microsoft Office 365? It’s true! The latest versions of PowerPoint include the capability. Start by heading over to the  Insert  tab, and select  Screen Recording , with an icon of a recorder and a screen. You can then select the specific area of your screen y ou want to record, and start the recording process whenever you want. When you’re done you can save the video as a separate file to access or embed as you see fit. Editing and control options are very limited after that, but it’s a great option for quick-and-dirty recording — especially if you’re doing it for a lo...

To set a breakpoint in your code use the native Python  import   pdb;pdb.set_trace()  call in your code

Proved to be a very useful resource for me ! http://www.tutorialspoint.com/python/python_reg_expressions.htm PYTHON REGULAR EXPRESSIONS http://www.tutorialspoint.com/python/python_reg_expressions.htm Copyright © tutorialspoint.com A  regular expression  is a special sequence of characters that helps you match or find other strings or sets of strings, using a specialized syntax held in a pattern. Regular expressions are widely used in UNIX world. The module  re  provides full support for Perl-like regular expressions in Python. The re module raises the exception re.error if an error occurs while compiling or using a regular expression. We would cover two important functions, which would be used to handle regular expressions. But a small thing first: There are various characters, which would have special meaning when they are used in regular expression. To avoid any confusion while dealing with regular expressions, we would use Raw Strings as  r'e...

This is a very important concept in Python where the behavior of pass by value & pass by reference varies with lists compared to immutable data types like strings. Source  http://www.python-course.eu/passing_arguments.php Parameter Passing "call by value" and "call by name" The most common evaluation strategy when passing arguments to a function has been call by value and call by reference: Call by Value The most common strategy is the call-by-value evaluation, sometimes also called pass-by-value. This strategy is used in C and C++ for example. In call-by-value, the argument expression is evaluated, and the result of this evaluation is bound to the corresponding variable in the function. So, if the expression is a variable, a local copy of its value will be used, i.e. the variable in the caller's scope will be unchanged when the function returns. Call by Reference In call-by-reference evaluation, which is also known as pass-by-reference, a fun...
