Python functions, Parameters, Arguments, args and kwargs

Python functions A function is a construct that helps us perform some action using a block of code (the body of the function), sometime based on input parameters. These functions can take different forms and can do a lot to allow your functional code base to be effective, To define a function, you use the…

List comprehensions, break-continue, exception handling in Python

As we have learned for loop to walk through a sequence, and do something with each item, at least read some value from it. There is a scenario, similar to what we saw with the last example in the for-loop introduction, that involves making a new list from the result of doing an operation on…

This can be tested using special built-in function: id(). We use is as the identity comparison operator, and the result here shows that var and the var3 have the…

Data types in Python

Now let’s discover data types that we can use to manipulate more data and do more things, such as lists, sets, and dictionaries. Lists A list is a sequence of arbitrary objects. You remember we said that strings are a sequence of (text) characters, so some of the things we already seen about strings apply…

Let’s quickly explore the first tools and basic syntax rules for a beginner to start using Python. But before that, know that when needed, you can find documentation on the Python.org site and many online resources, including sites like StackOverflow. Printing things We use the print() function to print stuff in Python. This is essential…
