1. Variables and Data Types:
   • Variables: Variables are used to store data values. In Python, you don't need to declare the type of a variable; Python infers it automatically. Variable names are case-sensitive.

x = 5  # integer
y = "Hello"  # string
z = 3.14  # float
is_true = True  # boolean

*   **Data Types:** Python has several built-in data types, including:
    *   **Integer (int):** Represents whole numbers (e.g., 5, -10, 0).
    *   **String (str):** Represents a sequence of characters (e.g., "Hello", "Python").
    *   **Float (float):** Represents floating-point numbers (e.g., 3.14, -2.5).
    *   **Boolean (bool):** Represents True or False values.
    *   **List:** Represents an ordered collection of items (e.g., `[1, 2, 3]`, `["apple", "banana", "cherry"]`).
    *   **Tuple:** Represents an ordered, immutable collection of items (e.g., `(1, 2, 3)`, `("apple", "banana", "cherry")`).
    *   **Dictionary:** Represents a collection of key-value pairs (e.g., `{"name": "Alice", "age": 30}`).

2. Operators:
   • Arithmetic Operators: Used to perform mathematical operations.

+  # addition
-  # subtraction
*  # multiplication
/  # division
%  # modulus (remainder)
** # exponentiation
// # floor division (integer division)

*   **Comparison Operators:** Used to compare values.

== # equal to
!= # not equal to
>  # greater than
<  # less than
>= # greater than or equal to
<= # less than or equal to

*   **Logical Operators:** Used to combine or modify boolean expressions.

and # logical AND
or  # logical OR
not # logical NOT

3. Control Flow:
   • If Statements: Used to execute code based on a condition.

x = 5
if x > 0:
    print("x is positive")
elif x < 0:
    print("x is negative")
else:
    print("x is zero")

*   **For Loops:** Used to iterate over a sequence of items.

for i in range(5):
    print(i)

*   **While Loops:** Used to execute code repeatedly as long as a condition is true.

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

4. Functions:
   • Functions are reusable blocks of code that perform a specific task. You can define your own functions using the def keyword.

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

greet("Alice")

5. Input and Output:
   • Input: The input() function is used to get input from the user.

name = input("Enter your name: ")
print("Hello, " + name + "!")

*   **Output:** The `print()` function is used to display output to the console.

print("Hello, world!")
