Variables and Data Types of Python by Meta Ai | Ballu Python 835430

 Here's the information on variables and data types in Python, along with practical examples:

Variables in Python

In Python, variables are used to store and manipulate data. To assign a value to a variable, use the assignment operator (=).

Example:

x = 5  # x is an integer variable

y = "Hello"  # y is a string variable

print(x)  # Output: 5

print(y)  # Output: Hello

Data Types in Python

Python has several built-in data types:

1. Integers (Int)

Integers are whole numbers.

Example:

x = 5

y = -10

print(x)  # Output: 5

print(y)  # Output: -10

2. Floats (Float)

Floats are decimal numbers.

Example:

x = 3.14

y = -0.5

print(x)  # Output: 3.14

print(y)  # Output: -0.5

3. Strings (Str)

Strings are sequences of characters.

Example:

x = "Hello"

y = 'World'

print(x)  # Output: Hello

print(y)  # Output: World

4. Boolean (Bool)

Booleans represent true or false values.

Example:

x = True

y = False

print(x)  # Output: True

print(y)  # Output: False

5. Lists (List)

Lists are ordered collections of items.

Example:

x = [1, 2, 3, "Hello", True]

print(x)  # Output: [1, 2, 3, 'Hello', True]

print(x[0])  # Output: 1

print(x[4])  # Output: True

6. Tuples (Tuple)

Tuples are ordered, immutable collections of items.

Example:

x = (1, 2, 3, "Hello", True)

print(x)  # Output: (1, 2, 3, 'Hello', True)

print(x[0])  # Output: 1

print(x[4])  # Output: True

7. Dictionaries (Dict)

Dictionaries are unordered collections of key-value pairs.

Example:

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

print(x)  # Output: {'name': 'John', 'age': 30, 'city': 'New York'}

print(x["name"])  # Output: John

print(x["age"])  # Output: 30

8. Sets (Set)

Sets are unordered, mutable collections of unique items.

Example:

x = {1, 2, 3, "Hello", True}

print(x)  # Output: {1, 2, 3, 'Hello', True}
