Python Mastery for Beginners

Discover why Python is simple by writing your first code in VS Code, adding two numbers, and printing the result to see a, b, and a+b.

Explore what Python is and why to choose it. Python is a simple, dynamic, high-level, object-oriented, general-purpose language with English-like syntax for web, data science, machine learning, testing, cloud computing.

Install python and Visual Studio Code on Windows, using python.org downloads, run the setup, add path, and verify installation with cmd, then install and open VS Code.

Learn how to create variables in Python by assigning values to named containers with syntax like name = value, and print them using print statements, noting Python is dynamic.

Explore the three essential inbuilt Python functions: print, type, and id, and learn how to print variables, inspect data types, and view memory locations.

Explore the input function in Python, which captures data from the user via a console message, stores it in a variable, and demonstrates with an example of two numbers.

learn how the eval function evaluates expressions and converts string input from the input function into original data types like integers, floats, and booleans.

explore python's print function, a built-in tool for printing messages and variable values; manage line breaks and spacing using end and separator attributes for flexible output.

Explore what an identifier is in Python and apply rules to define identifiers for variables, functions, classes, and methods, including alphanumeric characters, no leading digits, underscores, and case sensitivity.

Explore Python keywords, learn why reserved words can't be identifiers, and print the full keyword list using import keyword and keyword.kwlist in VSCode.

Explore Python data types, including integers, floats, strings, booleans, complex, and common collections like lists, tuples, sets, dictionaries, range, and frozen set; learn with examples and detailed explanations.

Learn how the integer data type in Python stores whole numbers, both positive and negative, with examples like a equals ten and number two equals -89.

Master the float data type in Python, representing floating point values with decimals. Learn to create and test numbers like 10.5 and -20.5 using type() to identify float values.

Explain the boolean data type and its use for true or false outcomes. Show Python examples like 20 > 21 yields false and age less than zero yields true.

Explore the string data type in Python, defined by text inside single or double quotes. Learn how Python treats quoted content as strings and prints a variable's type.

Learn how Python stores string data as memory arrays and assigns forward (positive) and reverse (negative) indexing to each character, with zero-based positions from left to right.

Learn to slice strings using start and end indices in Python, extracting multiple elements with zero-based indexing, and understand how end indices subtract one.

Explore string slicing in Python using a step value to print alternate elements, with start and end indices and positive or negative steps, illustrated by examples.

Learn to reverse strings by using negative step values in Python slicing. Explore how start points, end points, and negative indexing control slices from right to left.

Explore Python's list data type as an ordered, mutable, heterogeneous collection that preserves insertion order, allows duplicates, and supports creation with brackets and manipulation via append, indexing, and slicing.
