Quick Recap of Essential Python Concepts 😄👇 Python is a versatile and beginner-friendly programming language widely used in data science, web development, and automation. Here's a quick overview of some fundamental concepts: 1.  Variables:     *   Variables are used to store data values. They are assigned using the = operator.  Example: x = 10, name = "Alice" 2.  Data Types:     *   Python has several built-in data types:         *   Integer (int): Whole numbers (e.g., 1, -5).         *   Float (float): Decimal numbers (e.g., 3.14, -2.5).         *   String (str): Textual data (e.g., "Hello", 'Python').         *   Boolean (bool): True or False values.         *   List: Ordered collection of items (e.g., [1, 2, "apple"]).         *   Tuple: Ordered, immutable collection (e.g., (1, 2, "apple")).         *   Dictionary: Key-value pairs (e.g., {"name": "Alice", "age": 30}). 3.  Operators:     *   Python supports various operators for performing operations:         *   Arithmetic Operators: +, -, *, /, // (floor division), % (modulus), * (exponentiation).         *   Comparison Operators: ==, !=, >, <, >=, <=.         *   Logical Operators: and, or, not.         *   Assignment Operators: =, +=, -=, *=, /=, etc. 4.  Control Flow:     *   Control flow statements determine the order in which code is executed:         *   if, elif, else: Conditional execution.         *   for loop: Iterating over a sequence (list, string, etc.).         *   while loop: Repeating a block of code as long as a condition is true. 5.  Functions:     *   Functions are reusable blocks of code defined using the def keyword.

        def greet(name):
            print("Hello, " + name + "!")
        greet("Bob")  # Output: Hello, Bob!
        

6.  Lists:     *   Lists are ordered, mutable (changeable) collections.     *   Create: my_list = [1, 2, 3, "a"]     *   Access: my_list[0] (first element)     *   Modify: my_list.append(4), my_list.remove(2) 7.  Dictionaries:     *   Dictionaries store key-value pairs.     *   Create: my_dict = {"name": "Alice", "age": 30}     *   Access: my_dict["name"] (gets "Alice")     *   Modify: my_dict["city"] = "New York" 8.  Loops:     *  For Loops:

        my_list = [1, 2, 3]
        for item in my_list:
            print(item)
        

*   While Loops:

        count = 0
        while count < 5:
            print(count)
            count += 1
        

9.  String Manipulation:     *   Slicing: my_string[1:4] (extracts a portion of the string)     *   Concatenation: "Hello" + " " + "World"     *   Useful Methods: .upper(), .lower(), .strip(), .replace(), .split() 10. Modules and Libraries:     *   import statement is used to include code from external modules (libraries).     *   Example:

        import math
        print(math.sqrt(16))  # Output: 4.0

There's a floating-point number in Python and you need to output it as a percentage - use the % format in the f-string

x = .023
print(f'{x:.2%}')  # 2.30%

x = .02375
print(f'{x:.2%}')  # 2.38% -- rounded off!

x = 1.02375
print(f'{x:.2%}')  # 102.38%
