How to Create an Array in Python In Python, arrays are generally used to store multiple values of the same type in a single variable. The array module in Python allows you to create and initialize an array and for that, you first need to import it first. Now, let’s look at the exa...

Activating a virtual environment modifies the PATH and shell variables to point to the specific isolated Python set-up you created. PATH is an environmental variable in Linux and other Unix-like operating systems that tells the shell which directories to search for executable files (i.e., ready-...

Declaring a variable says a variable exists with this name, but itdoesn't have a value yet. After you've declared the variable, you then have toinitializeit with a value. Pythondoesn't have the concept of declaring a variable or initializing variables. Other programming languages sometimes do...

We can tell the type of the variable using this and not initialize it with any value. The new PEP 526 introduced the syntax for annotating variables of the required type (including class variables and instance variables) without comments. ...
A small tip, if you aim to lower your program's memory footprint: don't delete instance attributes, and make sure to initialize all attributes in your __init__!▶ Minor Ones *join() is a string operation instead of list operation. (sort of counter-intuitive at first usage) 💡 Expl...
Functions as First-Class Objects Functions in Python are first class citizens. This means that they support operations such as being passed as an argument, returned from a function, modified, and assigned to a variable. This property is crucial as it allows functions to be treated like any oth...
In this tutorial, you'll learn how to leverage other apps and programs that aren't Python, wrapping them or launching them from your Python scripts using the subprocess module. You'll learn about processes all the way up to interacting with a process as
