In this example we look for all the “getters” in a program. Programmers moving to Python from Java are often tempted to write lots of getter and setter methods, rather than use properties. We might want to find those methods. Using the member predicateFunction.getName(), we can list al...
Explore Program Advantages of Using Functions in Python Code Reusability: Write once and reuse many times without typing the same logic. Organizing the code: The bigger program is divided into multiple parts using a function that helps in the easy handling of the program. Better Readability: It...

TYPES OF ARGUMENTS IN PYTHON DEFAULT An argument can have a default value and this is done by using (=), assignment operator. In case, we do not pass any argument then the default value is returned. KEYWORD Sometimes we are not aware of the order in which arguments were passed, so Pyt...

As in other programming languages, it's often essential in Python to break your program into reusable chunks. A primary means of doing that is by usingfunctions. For example, we could rewrite thewhileloop code example in the previous unit as a formal function: ...
If you have usedhelp()in Python, then you have already seen the usage of docstrings! What it does is just fetch the__doc__attribute of that function and displays it in a neat manner for you. You can try it out on the function above - just includehelp(print_max)in your program. Re...
Functions in Python You use functions in programming to bundle a set of instructions that you want to use repeatedly or that, because of their complexity, are better self-contained in a sub-program and called when needed. That means that a function is a piece of code written to carry out...
