python
name = “Alice”
age = 30

* **Data Types:** Data types define the kind of data a variable can hold. Common data types include:
* **Integer (int):** Whole numbers (e.g., 10, -5, 0).
* **Float (float):** Decimal numbers (e.g., 3.14, -2.5).
* **String (str):** Text (e.g., “Hello”, “World”).
* **Boolean (bool):** True or False values.

* **Operators:** Operators are symbols that perform operations on variables and values. Common operators include:
* **Arithmetic operators:** `+` (addition), `-` (subtraction), `*` (multiplication), `/` (division), `%` (modulo).
* **Comparison operators:** `==` (equal to), `!=` (not equal to), `>` (greater than), `<` (less than), `>=` (greater than or equal to), `<=` (less than or equal to). * **Logical operators:** `and`, `or`, `not`. * **Control Flow:** Control flow statements allow you to control the order in which code is executed. Common control flow statements include: * **If-else statements:** Execute different blocks of code based on a condition. python age = 20 if age >= 18:
print(“You are an adult.”)
else:
print(“You are a minor.”)

* **Loops (for and while loops):** Repeat a block of code multiple times.

python
# For loop
for i in range(5):
print(i)

# While loop
count = 0
while count < 5: print(count) count += 1 * **Functions:** Functions are reusable blocks of code that perform a specific task. python def greet(name): print("Hello, " + name + "!") greet("Alice") # Output: Hello, Alice! * **Data Structures:** Data structures are ways of organizing and storing data. Common data structures include: * **Lists (Arrays):** Ordered collections of items. python my_list = [1, 2, 3, "Hello", True] print(my_list[0]) # Output: 1 * **Dictionaries (Hash Maps):** Collections of key-value pairs. python my_dict = { "name": "Alice", "age": 30 } print(my_dict["name"]) # Output: Alice Learn these concepts through online courses, tutorials, and books.
