“Building a Strong Foundation: Python Fundamentals Explained”

/Variables: In Python, a variable is a container for storing a value. You can create concise and meaningful variable names to represent data. Remember that Python is not statically typed, which means you don’t need to declare the type explicitly when defining a variable¹.

1. Data Types: Python has several built-in data types:

   • Strings: Used for text data and can be manipulated using various string operations.

   • Integers: Whole numbers without decimal points.

   • Floating-Point Numbers: Represent real numbers with decimal points¹.

2. Operators: Python supports various operators for performing mathematical and logical operations:

   • Arithmetic Operators: +, -, *, /, %, etc.

   • Comparison Operators: ==, !=, <, >, <=, >=, etc.

   • Logical Operators: and, or, not¹.

3. Conditional Statements:

   • Use if, elif, and else to make decisions based on conditions.

4. Loops:

   • for Loop: Iterates over a sequence (e.g., a list, tuple, or string).

   • while Loop: Repeats a block of code while a condition is true.

5. Functions:

   • Define reusable blocks of code using functions.

   • Functions can take parameters and return values.

6. Libraries:

   • Python has a rich ecosystem of libraries and frameworks.

   • For example, NumPy is a library for working with numerical data in Python¹.
