  • Python is a high-level programming language that is widely used for: 
    • Software development 
    • Web applications
    • Data analysis 
    • Machine learning
    • Automation
Feature Explanation
Easy to read Python uses simple English-like syntax making it more beginner-friendly.
High-level No need to worry about low-level details like memory management.
Interpreted Python code runs line by line, making it easier to test and debug.
Versatile Can be used for web development, game creation, data science, AI, etc.
Large community Lots of tutorials, libraries, and support available online.

Python uses indentation to define blocks of code (e.g. loops and selection).

  • Incorrect indentation causes syntax errors.
  • Statements are usually written one per line. Semicolons are not needed.
  • Variables and data types:
    • A variable stores data and is created using the assignment operator =.
    • Common data types: 
      • int – whole numbers
      • float – decimal numbers
      • str – text (strings)
      • bool – Boolean values (True or False) 
  • Iteration (loops):
    • for loops are used when the number of repetitions is known. 
    • while loops repeat while a condition is true.
    • break can stop a loop early; continue skips to the next iteration.
