====== Python's basic syntax and data types. ======


## Python Basic Syntax:

Python is known for its clean and readable syntax. Here are some fundamental aspects of Python's syntax:

1. **Indentation**: Python uses indentation (whitespace) to define blocks of code, like loops and functions, instead of using braces `{}` as in many other programming languages.

2. **Comments**: You can add comments using the `#` symbol. Comments are ignored by the interpreter and are useful for adding explanations to your code.

 # This is a comment
 
3. **Print Statements**: The `print()` function is used to output text or variables to the console.

 print("Hello, world!")
 
## Python Data Types:

Python supports various data types that allow you to represent and manipulate different kinds of values. Some common data types include:

1. **Numbers**: Python supports integers and floating-point numbers for numerical operations.

integer_num = 10

float_num = 3.14
 
2. **Strings**: Strings are used to represent text. They can be enclosed in either single (`'`) or double (`"`) quotes.

 
my_string = "Hello, Python!"
 

3. **Lists**: Lists are ordered collections of items, and they can contain elements of different types.
 
my_list = [1, 2, "three", 4.0]
 
4. **Tuples**: Tuples are similar to lists, but they are immutable (cannot be modified after creation).


my_tuple = (1, 2, 3)


5. **Dictionaries**: Dictionaries store key-value pairs and are often used to represent mappings.


my_dict = {"name": "John", "age": 30, "city": "New York"}


6. **Sets**: Sets are unordered collections of unique elements.


my_set = {1, 2, 3, 3, 4}


7. **Booleans**: Booleans represent either `True` or `False` values and are used for logical operations.

 
is_true = True

is_false = False
 

## Variables and Assignment:

You can assign values to variables using the `=` operator. Variable names can contain letters, numbers, and underscores, but they cannot start with a number.

 
x = 5

name = "Alice"
 

Remember, Python is dynamically typed, which means you don't need to declare the data type of a variable explicitly.
