• 1.
  Python Basics: DataTypes, Expressions, Operators, Variables Fundamentals of Python programming Covers core building blocks of writing Python code
• 2.
  Python Data Types int– Integer (e.g., 10, -5) float – Floating-point number (e.g., 3.14, -0.001) str – String (e.g., 'hello', "Python") bool – Boolean (True or False) list, tuple, set, dict – Collection types
• 3.
  Expressions in Python Anexpression is a combination of values, variables, and operators Examples: 3 + 5, a * b, (x + y) / 2 Can evaluate to a single value
• 4.
  Python Operators Arithmetic: +,-, *, /, %, **, // Comparison: ==, !=, >, <, >=, <= Logical: and, or, not Assignment: =, +=, -=, *=, /=
• 5.
  Variables in Python Usedto store data values No need to declare type explicitly Examples: x = 10, name = 'Alice' Variable names must start with a letter or underscore
• 6.
  Assignment Statements Assigns valueto a variable using '=' Example: total = price * quantity Can also use multiple assignments: a, b = 5, 10
• 7.
  Best Practices Use meaningfulvariable names (e.g., score, age) Follow snake_case for variable naming Avoid using Python keywords as variable names
• 8.
  Conclusion Data types andvariables are foundational in Python Expressions and operators help build logic Assignments allow manipulation and storage of data
