Python Basics


In this section, you’ll learn the basic Python. If you’re completely new to Python programming, this Python basics section is perfect for you.

After completing the tutorials, you’ll be familiar with Python programming.

Section 1. Fundamentals

  • Syntax – introduce you to the basic Python programming syntax.
  • Variables – explain to you what variables are and how to create concise and meaningful variables.
  • Strings – learn about the string data and some basic string operations.
  • Numbers – introduce to you the commonly-used number types including integers and floating-point numbers.
  • Booleans – explain the Boolean data type, falsy and truthy values in Python.
  • Constants – show you how to define constants in Python.
  • Comments – learn how to make notes in your code.
  • Type conversion – learn how to convert a value of one type to another e.g., converting a string to a number.

Section 2. Operators

  • Comparison operators – introduce you to the comparison operators and how to use them to compare two values.
  • Logical operators – show you how to use logical operators to combine multiple conditions.

Section 3. Control flow

  • if…else statement – learn how to execute a code block based on a condition.
  • Ternary operator – introduce you to the Python ternary operator that makes your code more concise.
  • for loop with range() – show you how to execute a code block for a fixed number of times by using the for loop with range() function.
  • while– show you how to execute a code block as long as a condition is True.
  • break – learn how to exit a loop prematurely.
  • continue – show you how to skip the current loop iteration and start the next one.
  • pass – show you how to use the pass statement as a placeholder.

Section 4. Functions

  • Python functions – introduce you to functions in Python, how to define functions, and reuse them in the program.
  • Default parameters – show you how to specify the default values for function parameters.
  • Keyword arguments – learn how to use the keyword arguments to make the function call more obvious.
  • Recursive functions – learn how to define recursive functions in Python.
  • Lambda Expressions – show you how to define anonymous functions in Python using lambda expressions.
  • Docstrings – show you how to use docstrings to document a function.

Section 5. Lists

Section 6. Dictionaries

  • Dictionary – introduce you to the dictionary type.
  • Dictionary comprehension – show you how to use dictionary comprehension to create a new dictionary from an existing one.

Section 7. Sets

  • Set – explain to you the Set type and show you how to manipulate set elements effectively.
  • Set comprehension – explain to you the set comprehension so that you can create a new set based on an existing set with a more concise and elegant syntax.
  • Union of Sets – show you how to union two or more sets using the union() method or set union operator (&).
  • Intersection of Sets – show you how to intersect two or more sets using the intersection() method or set intersection operator (|).
  • Difference of sets – learn how to find the difference of sets using the set difference() method or set difference operator (-)
  • Symmetric Difference of sets – guide you on how to find the symmetric difference of sets using the symmetric_difference() method or the symmetric difference operator (^).
  • Subset – check if a set is a subset of another set.
  • Superset – check if a set is a superset of another set.
  • Disjoint sets – check if two sets are disjoint.

Section 8. Exception handling

  • try…except – show you how to handle exception more gracefully using the try…except statement.
  • try…except…finally – learn how to execute a code block whether an exception occurs or not.
  • try…except…else – explain to you how to use the try…except…else statement to control the follow of the program in case of exceptions.

Section 9. More on Python Loops

  • for…else – explain to you the for else statement.
  • while…else – discuss the while else statement.
  • do…while loop emulation – show you how to emulate the do…while loop in Python by using the while loop statement.

Section 10. More on Python functions

  • Unpacking tuples – show you how to unpack a tuple that assigns individual elements of a tuple to multiple variables.
  • *args Parameters – learn how to pass a variable number of arguments to a function.
  • **kwargs Parameters – show you how to pass a variable number of keyword arguments to a function.
  • Partial functions – learn how to define partial functions.
  • Type hints – show you how to add type hints to parameters and return value of a function and how to use the static type checker (mypy) to check the type statically.

Section 11. Modules & Packages

  • Modules – introduce you to the Python modules and show you how to write your own modules.
  • Module search path – explain to you how the Python module search path works when you import a module.
  • __name__ variable – show you how to use the __name__ variable to control the execution of a Python file as a script or as a module.
  • Packages – learn how to use packages to organize modules in more structured ways.

Section 12. Working with files

Section 13. Working Directories

Section 14. Third-party Packages, PIP, and Virtual Environments

Section 15. Strings

  • F-strings – learn how to use the f-strings to format text strings in a clear syntax.
  • Raw strings – use raw strings to handle strings that contains the backslashes.
  • Backslash – explain how Python uses the backslashes (\) in string literals.
