In shell scripts, the shebang line (#!) specifies the path to the interpreter that should execute the file. You can place it at the top of your Python file to tell the shell how to run your script, allowing you to execute the script directly without typing python before the script name. The shebang is essential for Unix-like systems but ignored on Windows unless using specific compatibility layers. By the end of this video course, you’ll understand that: A shebang […]

You may have begun your Python journey interactively, exploring ideas within Jupyter Notebooks or through the Python REPL. While that’s great for quick experimentation and immediate feedback, you’ll likely find yourself saving code into .py files. However, as your codebase grows, your Python script structure efficiency becomes increasingly important. Transitioning from interactive environments to structured scripts helps promote readability, enabling better collaboration and more robust development practices. This tutorial transforms messy scripts into well-organized, shareable code. Along the way, you’ll […]

Interactive Quiz ⋅ 11 QuestionsBy Leodanis Pozo Ramos Share In this quiz, you’ll test your understanding of control flow structures in Python. Control flow dictates the order in which your code executes, letting you make choices, repeat work, and handle exceptions to build more flexible, reliable programs. For hands-on examples and a deeper dive, check out the tutorial Control Flow Structures in Python. The quiz contains 11 questions and there is no time limit. You’ll get 1 point for each […]

Python’s control flow structures allow you to dictate the order in which statements execute in your program. You can do this by using structures like conditionals, loops, and others. Normally, your code executes sequentially. You can modify this behavior using control flow structures that let you make decisions, run specific pieces of code in response to certain conditions, repeat a code block several times, and more. Knowing about control flow structures is a fundamental skill for you as a Python […]

The concept of scope rules how variables and names are looked up in your code. It determines the visibility of a variable within the code. The scope of a name or variable depends on the place in your code where you create that variable. The Python scope concept is generally presented using a rule known as the LEGB rule. The letters in the acronym LEGB stand for Local, Enclosing, Global, and Built-in scopes. This summarizes not only the Python scope […]
